+
+| Risk | Impact | Probability | Mitigation |
+|------|--------|-------------|------------|
+| LVM migration data loss | CRITICAL | MEDIUM | Comprehensive backups, testing, consider rebuild |
+| Molecule test complexity | HIGH | MEDIUM | Start simple, iterate, use Docker not libvirt |
+| CI/CD pipeline setup delays | HIGH | MEDIUM | Use Gitea Actions (simpler), prioritize basic tests |
+| derp VM unrecoverable | HIGH | LOW | Document rebuild procedure using deploy_linux_vm |
+| Time constraints | MEDIUM | HIGH | Prioritize P0/P1 tasks, defer P3 tasks |
+
+### Medium Risks
+
+| Risk | Impact | Probability | Mitigation |
+|------|--------|-------------|------------|
+| Docker security findings | MEDIUM | HIGH | Plan remediation time, may need container rebuild |
+| Breaking changes during testing | MEDIUM | MEDIUM | Use check mode, test in dev environment first |

+## Host-by-Host Analysis
+
+### pihole (pihole.grokbox) - 192.168.122.12
+
+**Status:** ✅ Operational
+**OS:** Debian
+**Uptime:** 23 days, 11:03
+**Role:** DNS/Ad-blocking service
+
+#### System Resources
+- **CPU:** Load average: 0.27, 0.11, 0.06 (healthy)
+- **Memory:** 1.9GB total, 401MB used, 1.5GB available (healthy)
+- **Swap:** **0B** ❌ CRITICAL
+- **Disk:** /dev/vda1 - 7.7GB total, 1.9GB used (25% utilization)
+
+#### Critical Findings
+
+**1. No Swap Configured** ❌ **CRITICAL**
+- **Finding:** System has 0B swap space
+- **Risk:** High risk of OOM killer activation under memory pressure
+- **CLAUDE.md Requirement:** Minimum 1GB swap (lv_swap)
+- **Impact:** Service interruptions, potential data loss
+- **Remediation:**
+  ```bash
+  # Option 1: Add swap file (quick fix)
+  dd if=/dev/zero of=/swapfile bs=1M count=2048
+  chmod 600 /swapfile
+  mkswap /swapfile
+  swapon /swapfile
+  echo '/swapfile none swap sw 0 0' >> /etc/fstab
+
+  # Option 2: LVM swap (CLAUDE.md compliant)
+  # Requires LVM migration (see below)
+  ```
+
+**2. No LVM Configuration** ⚠️ **HIGH**
+- **Finding:** Using traditional partitioning (/dev/vda1 mounted on /)
+- **CLAUDE.md Violation:** All systems must use LVM
+- **Missing Volumes:**
+  - lv_opt → /opt (3GB)
+  - lv_tmp → /tmp (1GB, noexec)
+  - lv_home → /home (2GB)
+  - lv_var → /var (5GB)
+  - lv_var_log → /var/log (2GB)
+  - lv_var_tmp → /var/tmp (5GB, noexec)
+  - lv_var_audit → /var/log/audit (1GB)
+  - lv_swap → swap (2GB)
+- **Risk:** Cannot dynamically resize partitions, difficult disaster recovery
+- **Remediation:** See "LVM Migration Plan" section below
+
+**3. Docker Running with Unknown Security Posture** ⚠️ **MEDIUM**
+- **Finding:** Docker daemon running (PID 627, consuming 4.0% memory)
+- **Containers:** Multiple overlay mounts detected
+- **Security Concerns:**
+  - Container escape risk
+  - Privileged container usage unknown
+  - Network isolation unknown
+  - Resource limits unknown
+- **Remediation:** Perform Docker security audit (see section below)
+
+#### High Priority Findings
+
+**4. Unattended Upgrades Running** ℹ️ **INFO**
+- **Finding:** `/usr/share/unattended-upgrades/unattended-upgrade-shutdown` active
+- **Status:** This is expected behavior per CLAUDE.md
+- **Action:** Verify configuration aligns with security-only updates
+
+#### Recommendations
+1. **Immediate:** Configure swap space (Option 1: swap file)
+2. **Short-term:** Conduct Docker security audit
+3. **Long-term:** Plan LVM migration or document exception rationale
+

+
+### mymx / cow.mymx.me - 192.168.122.119
+
+**Status:** ✅ Operational (after SSH key deployment)
+**OS:** Debian
+**Hostname:** cow.mymx.me
+**Role:** Mail server (mailcow)
+
+#### System Resources
+- **CPU:** Multi-core, moderate load
+- **Memory:** 16GB total, 6.1GB used, 9.5GB available (healthy)
+- **Swap:** 976MB total, 439MB used (45% utilization) ✅ COMPLIANT
+- **Disk:** LVM configured (/dev/mapper/mymx--vg-root - 48GB, 57% used) ✅ COMPLIANT
+
+#### Critical Findings
+
+**1. SSH Authentication Failure (RESOLVED)** ✅
+- **Initial Finding:** Permission denied (publickey)
+- **Root Cause:** `ansible` user did not exist, SSH key not deployed
+- **Remediation Applied:**
+  - Created `ansible` user
+  - Deployed SSH public key
+  - Configured passwordless sudo
+- **Status:** ✅ RESOLVED - Host now accessible via Ansible
+
+**2. QEMU Guest Agent Not Responding** ⚠️ **HIGH**
+- **Finding:** `libvirt: QEMU Driver error : Guest agent is not connected`
+- **Impact:**
+  - Cannot get accurate VM state from hypervisor
+  - Snapshot filesystem freeze unavailable
+  - Limited VM management capabilities from libvirt
+- **Remediation:**
+  ```bash
+  ansible mymx -b -m apt -a "name=qemu-guest-agent state=present"
+  ansible mymx -b -m systemd -a "name=qemu-guest-agent state=started enabled=yes"
+  ```
+
+#### High Priority Findings
+
+**3. Heavy Service Load** ⚠️ **MEDIUM**
+- **Finding:** Multiple resource-intensive services:
+  - ClamAV clamd: 8.7% memory (1.4GB)
+  - YaCy search: 7.9% memory (1.3GB) + high CPU
+  - OpenWebUI: 4.8% memory (800MB)
+  - MariaDB: 2.0% memory (328MB)
+  - Redis: Running
+- **Concerns:**
+  - Memory pressure (6.1GB / 16GB used)
+  - Swap usage (45%)
+  - CPU contention risk
+- **Recommendations:**
+  - Monitor resource trends
+  - Consider vertical scaling (increase RAM) if swap usage grows
+  - Review YaCy necessity (search engine consuming significant resources)
+  - Implement resource limits for containers
+
+**4. Extensive Docker Usage** ⚠️ **MEDIUM**
+- **Finding:** 24 Docker overlay mounts detected
+- **Services:** Mailcow components running in containers
+- **Security Concerns:** Same as pihole (see Docker audit section)
+
+#### LVM Status
+✅ **COMPLIANT** - LVM is properly configured:
+- Volume Group: `mymx-vg`
+- Root volume: `/dev/mapper/mymx--vg-root` (48GB)
+- Swap: LVM-based (976MB)
+
+#### Recommendations
+1. **Immediate:** Install qemu-guest-agent
+2. **Short-term:** Monitor resource usage trends
+3. **Medium-term:** Conduct Docker security audit
+4. **Long-term:** Plan capacity expansion if memory usage continues growing
+

+
+### derp - 192.168.122.99
+
+**Status:** ❌ UNREACHABLE
+**Error:** `Permission denied (publickey,password)`
+
+#### Critical Findings
+
+**1. SSH Authentication Failure** ❌ **CRITICAL**
+- **Finding:** Cannot connect via SSH with both key and password authentication
+- **Attempted Remediation:** Failed to connect via jump host
+- **Error Detail:** `Connection closed by UNKNOWN port 65535`
+- **Possible Causes:**
+  1. VM is not running
+  2. SSH service not running
+  3. Network connectivity issue
+  4. Firewall blocking connection
+  5. SSH configuration issue
+  6. System compromised or in rescue mode
+
+#### Immediate Actions Required
+1. **Check VM Status:**
+   ```bash
+   ansible grokbox -b -m shell -a "virsh list --all | grep derp"
+   ansible grokbox -b -m shell -a "virsh domstate derp"
+   ```
+
+2. **If VM is running, access via console:**
+   ```bash
+   ssh grokbox "virsh console derp"
+   ```
+
+3. **Verify network:**
+   ```bash
+   ansible grokbox -b -m shell -a "virsh domifaddr derp"
+   ansible grokbox -b -m shell -a "ping -c 3 192.168.122.99"
+   ```
+
+4. **Check SSH service (via console):**
+   ```bash
+   systemctl status sshd
+   journalctl -u sshd -n 50
+   ```
+
+5. **Check firewall (via console):**
+   ```bash
+   ufw status  # Debian/Ubuntu
+   iptables -L  # All systems
+   ```

+
+## Infrastructure-Wide Issues
+
+### Dynamic Inventory Warnings
+
+**Finding:** Invalid characters in group names
+```
+[WARNING]: Invalid characters were found in group names but not replaced
+```
+
+**Root Cause:** Libvirt dynamic inventory creates UUID-based groups with hyphens:
+- `7cd5a220-bea4-49a1-a44e-a247dbdfd085`
+- `6d714c93-16fb-41c8-8ef8-9001f9066b3a`
+- `9ede717f-879b-48aa-add0-2dfd33e10765`
+
+**Impact:** Potential compatibility issues with Ansible group operations
+
+**Remediation:**
+```yaml
+# inventories/development/libvirt_kvm.yml
+# Add group name sanitization
+keyed_groups:
+  - key: info.uuid | regex_replace('-', '_')
+    prefix: uuid
+    separator: "_"
+```
+
+### QEMU Guest Agent Deployment
+
+**Finding:** Guest agent not installed on VMs
+
+**Impact:**
+- Unreliable IP address discovery
+- No filesystem quiescing for snapshots
+- Limited VM management from libvirt
+
+**Remediation Playbook:**
+
+Create `playbooks/install_qemu_agent.yml`:
+```yaml
+---
+- name: Install QEMU Guest Agent on all VMs
+  hosts: kvm_guests
+  become: yes
+  tasks:
+    - name: Install qemu-guest-agent (Debian/Ubuntu)
+      apt:
+        name: qemu-guest-agent
+        state: present
+        update_cache: yes
+      when: ansible_os_family == "Debian"
+
+    - name: Install qemu-guest-agent (RHEL/Rocky/Alma)
+      yum:
+        name: qemu-guest-agent
+        state: present
+      when: ansible_os_family == "RedHat"
+
+    - name: Enable and start qemu-guest-agent
+      systemd:
+        name: qemu-guest-agent
+        state: started
+        enabled: yes
+
+    - name: Verify agent is running
+      systemd:
+        name: qemu-guest-agent
+      register: agent_status
+
+    - name: Display agent status
+      debug:
+        msg: "QEMU Guest Agent status: {{ agent_status.status.ActiveState }}"
+```
+
+---
+
+## Detailed Remediation Plans
+
+### Plan 1: Pihole LVM Migration
+
+**Complexity:** HIGH
+**Downtime:** 2-4 hours
+**Risk:** MEDIUM (data migration required)
+
+#### Prerequisites
+- Full backup of pihole data
+- Maintenance window scheduled
+- Secondary DNS available during migration
+
+#### Migration Steps
+
+**Option A: In-Place Migration (Complex)**
+1. Backup all data
+2. Add second disk to VM
+3. Create LVM on new disk
+4. Copy data to new LVM volumes
+5. Update fstab
+6. Update bootloader
+7. Reboot and verify
+8. Remove old disk
+
+**Option B: Redeploy with deploy_linux_vm role (Recommended)**
+1. Backup pihole configuration and data:
+   ```bash
+   # Backup Pi-hole configuration
+   pihole -a teleporter backup.tar.gz
+
+   # Backup Docker volumes (if used)
+   docker run --rm -v pihole_data:/data -v $(pwd):/backup alpine tar czf /backup/pihole_docker.tar.gz /data
+   ```
+
+2. Deploy new VM with LVM:
+   ```yaml
+   - hosts: grokbox
+     roles:
+       - role: deploy_linux_vm
+         vars:
+           deploy_linux_vm_name: pihole-new
+           deploy_linux_vm_hostname: pihole
+           deploy_linux_vm_os_distribution: debian-12
+           deploy_linux_vm_vcpus: 2
+           deploy_linux_vm_memory_mb: 2048
+           deploy_linux_vm_disk_size_gb: 30
+           deploy_linux_vm_use_lvm: true
+   ```
+
+3. Restore data to new VM
+4. Test functionality
+5. Update DNS records
+6. Decommission old VM
+
+**Option C: Document Exception**
+If pihole is ephemeral or easily replaceable:
+1. Document why LVM is not required
+2. Add to exceptions list in CLAUDE.md
+3. Ensure backup/restore procedures are in place
+
+#### Recommendation
+**Option B (Redeploy)** is recommended because:
+- Clean implementation of CLAUDE.md standards
+- Minimal risk (old VM remains until verified)
+- Opportunity to update to latest OS version
+- Practice for future VM deployments
+
+---
+
+### Plan 2: Docker Security Audit
+
+**Complexity:** MEDIUM
+**Duration:** 2-4 hours
+**Risk:** LOW (read-only analysis)
+
+#### Audit Checklist
+
+Create `playbooks/audit_docker.yml`:

+              - "{{ network_modes.stdout_lines | default(['None']) }}"
+
+      when: docker_installed.rc == 0
+```
+
+#### Security Hardening Recommendations
+
+Based on audit findings, apply these hardening measures:
+
+1. **Restrict Docker Socket Access**
+   ```bash
+   chmod 660 /var/run/docker.sock
+   chown root:docker /var/run/docker.sock
+   ```
+
+2. **Enable User Namespaces**
+   ```json
+   # /etc/docker/daemon.json
+   {
+     "userns-remap": "default"
+   }
+   ```
+
+3. **Configure Resource Limits (Mailcow example)**
+   ```yaml
+   # docker-compose.yml
+   services:
+     postfix:
+       mem_limit: 512m
+       cpus: 0.5
+   ```
+
+4. **Disable Privileged Containers** (review necessity)
+5. **Enable AppArmor/SELinux profiles**
+6. **Configure logging**:
+   ```json

+
+### Plan 3: Swap Configuration for Pihole
+
+**Complexity:** LOW
+**Duration:** 10 minutes
+**Risk:** LOW
+**Downtime:** None (can be done live)
+
+#### Quick Fix: Swap File
+
+Create `playbooks/configure_swap.yml`:
+
+```yaml
+---
+- name: Configure Swap on Systems Without It
+  hosts: kvm_guests
+  become: yes
+  vars:
+    swap_file_path: /swapfile
+    swap_size_mb: 2048  # 2GB
+  tasks:
+    - name: Check current swap
+      command: swapon --show
+      register: current_swap
+      changed_when: false
+      failed_when: false
+
+    - name: Check if swap file exists
+      stat:
+        path: "{{ swap_file_path }}"
+      register: swap_file
+
+    - block:
+        - name: Create swap file
+          command: dd if=/dev/zero of={{ swap_file_path }} bs=1M count={{ swap_size_mb }}
+          args:
+            creates: "{{ swap_file_path }}"
+
+        - name: Set swap file permissions
+          file:
+            path: "{{ swap_file_path }}"
+            mode: '0600'
+            owner: root
+            group: root
+
+        - name: Format swap file
+          command: mkswap {{ swap_file_path }}
+          when: not swap_file.stat.exists
+
+        - name: Enable swap file
+          command: swapon {{ swap_file_path }}
+          when: swap_file_path not in current_swap.stdout
+
+        - name: Add swap to fstab
+          lineinfile:
+            path: /etc/fstab
+            line: "{{ swap_file_path }} none swap sw 0 0"
+            state: present
+            backup: yes
+
+        - name: Verify swap is active
+          command: swapon --show
+          register: new_swap
+          changed_when: false
+
+        - name: Display swap status
+          debug:
+            var: new_swap.stdout_lines
+
+      when: current_swap.stdout | length == 0 or swap_size_mb > 0
+```
+
+Execute:
+```bash
+ansible-playbook playbooks/configure_swap.yml --limit pihole
+```
+
+---
+
+### Plan 4: Derp VM Recovery
+
+**Complexity:** MEDIUM
+**Duration:** 30-60 minutes
+**Risk:** MEDIUM
+
+#### Diagnostic Steps
+
+1. **Verify VM state:**
+   ```bash
+   ansible grokbox -b -m shell -a "virsh list --all"
+   ansible grokbox -b -m shell -a "virsh domstate derp"
+   ```
+
+2. **If VM is shut off, start it:**
+   ```bash
+   ansible grokbox -b -m shell -a "virsh start derp"
+   ```
+
+3. **Check console access:**
+   ```bash
+   ssh grokbox "virsh console derp"
+   # Press Enter to get login prompt
+   # Login as root
+   ```
+
+4. **From console, diagnose:**
+   ```bash
+   # Check network
+   ip addr show
+   ip route show
+   ping -c 3 192.168.122.1  # Test gateway
+
+   # Check SSH
+   systemctl status sshd
+   ss -tlnp | grep :22
+
+   # Check firewall
+   ufw status
+   iptables -L -n
+
+   # Check auth logs
+   tail -50 /var/log/auth.log  # Debian
+   ```
+
+5. **Deploy SSH key (from console):**
+   ```bash
+   # Create ansible user if needed
+   useradd -m -s /bin/bash ansible
+   mkdir -p /home/ansible/.ssh
+   chmod 700 /home/ansible/.ssh
+
+   # Add public key (paste manually via console)
+   cat > /home/ansible/.ssh/authorized_keys << 'EOF'
+   ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAILBrnivsqjhAxWYeuuvnYc3neeRRuHsr2SjeKv+Drtpu user@debian
+   EOF
+
+   chmod 600 /home/ansible/.ssh/authorized_keys
+   chown -R ansible:ansible /home/ansible/.ssh
+
+   # Configure sudo
+   echo "ansible ALL=(ALL) NOPASSWD:ALL" > /etc/sudoers.d/ansible
+   chmod 440 /etc/sudoers.d/ansible
+   ```
+
+6. **Test connectivity:**
+   ```bash
+   ansible derp -m ping
+   ```
+
+---

+

+
+## Overview
+
+User namespace remapping is a Docker security feature that maps container UID/GIDs to different values on the host, preventing container root from being host root.
+
+### Current Status
+
+| Host | User Namespaces | Risk Level | Implementation Priority |
+|------|-----------------|------------|------------------------|
+| pihole | Not configured | MEDIUM | Week 49 (after testing) |
+| mymx | Not configured | HIGH | Week 50 (mailcow complexity) |
+
+### Impact Assessment
+
+**Benefits:**
+- ✅ Container root ≠ host root (major security improvement)
+- ✅ Reduces container escape impact
+- ✅ CIS Docker Benchmark compliance (2.13)
+
+**Risks:**
+- ⚠️ **ALL containers must be recreated**
+- ⚠️ Volume permissions must be remapped
+- ⚠️ Breaking change for existing deployments
+- ⚠️ Mailcow may have specific requirements
+
+**Recommendation:** Test thoroughly in dev, then pihole, then mymx (last)
+
+---
+
+## Security Benefits
+
+### Without User Namespace Remapping (Current State)
+
+```
+Container:     Host:
+UID 0 (root) → UID 0 (root)     ❌ DANGEROUS
+UID 1000     → UID 1000
+```
+
+**Problem:** Container root can potentially escape and has host root privileges.
+
+### With User Namespace Remapping (Target State)
+
+```
+Container:     Host:
+UID 0 (root) → UID 165536       ✅ SAFE
+UID 1000     → UID 166536
+```
+
+**Benefit:** Container root is unprivileged user on host.
+
+---
+
+## Prerequisites
+
+### Before Starting Testing
+
+1. **VM Snapshots Created**
+   ```bash
+   ansible-playbook playbooks/backup_vm_snapshot.yml \
+     -e "target_vms=['pihole', 'mymx']"
+   ```
+
+2. **Rollback Procedures Reviewed**
+   - Read: `docs/runbooks/docker-configuration-rollback.md`
+   - Understand VM snapshot restore process
+   - Have emergency contact information ready
+
+3. **Maintenance Window Scheduled**
+   - Duration: 2-3 hours for testing
+   - Low-traffic period recommended
+   - Second person available for verification
+
+4. **Documentation Ready**
+   - This guide printed or accessible offline
+   - Docker and mailcow documentation available
+   - Notepad for documenting issues
+
+---
+
+## Testing Phase (Week 48-49)
+
+### Phase 1: Test Environment Setup (Week 48)
+
+**Objective:** Validate user namespace remapping with simple container
+
+#### Option A: Use derp VM (Recommended)
+
+```bash
+# 1. Start derp VM (if stopped)
+ssh grokbox "sudo virsh start derp"
+
+# 2. Create ansible user and configure SSH
+# (Use deploy_linux_vm role or manual setup)
+
+# 3. Install Docker
+ansible derp -m apt -a "name=docker.io state=present" -b
+
+# 4. Create snapshot before testing
+ansible-playbook playbooks/backup_vm_snapshot.yml \
+  -e "target_vms=['derp']"
+```
+
+#### Option B: Create temporary test container on existing host
+
+```bash
+# On pihole (low risk - only 1 container)
+# Create test container first
+
+docker run -d --name userns-test \
+  -v test-volume:/data \
+  alpine:latest sleep infinity
+```
+
+### Phase 2: Enable User Namespace Remapping (Week 48)
+
+#### Step 1: Configure Docker Daemon
+
+```bash
+# On test host (derp or pihole)
+sudo tee /etc/docker/daemon.json <<EOF
+{
+  "userns-remap": "default"
+}
+EOF
+
+# Validate syntax
+cat /etc/docker/daemon.json | jq '.'
+```
+
+#### Step 2: Restart Docker
+
+```bash
+# Stop all containers first
+docker stop $(docker ps -q)
+
+# Restart Docker daemon
+sudo systemctl restart docker
+
+# Verify it started
+sudo systemctl status docker
+
+# Check for user namespace in docker info
+docker info | grep -i "userns"
+# Should show: "userns": true
+```
+
+#### Step 3: Verify UID Mapping
+
+```bash
+# Check subuid/subgid configuration
+cat /etc/subuid
+cat /etc/subgid
+
+# Should show something like:
+# dockremap:165536:65536
+
+# Verify Docker is using remapping
+docker info --format '{{.SecurityOptions}}'
+```
+
+#### Step 4: Recreate Test Container
+
+```bash
+# Remove old container (data is in volume)
+docker rm userns-test
+
+# Recreate container
+docker run -d --name userns-test \
+  -v test-volume:/data \
+  alpine:latest sleep infinity
+
+# Verify it's running
+docker ps | grep userns-test
+```
+
+#### Step 5: Test Volume Permissions
+
+```bash
+# Create test file in container
+docker exec userns-test sh -c 'echo "test" > /data/test.txt'
+
+# Check file ownership on host
+# Volume location changed! It's now in:
+sudo ls -la /var/lib/docker/165536.165536/volumes/test-volume/_data/
+
+# UID should be 165536 (remapped root)
+
+# Test read/write in container
+docker exec userns-test cat /data/test.txt
+docker exec userns-test sh -c 'echo "test2" >> /data/test.txt'
+```
+
+### Phase 3: Test with Real Application (Week 48-49)
+
+#### Test Scenario 1: Simple Web Server (pihole preparation)
+
+```bash
+# Deploy nginx with volume
+docker run -d --name test-nginx \
+  -p 8080:80 \
+  -v nginx-data:/usr/share/nginx/html \
+  nginx:alpine
+
+# Test access
+curl http://localhost:8080
+
+# Create content
+docker exec test-nginx sh -c 'echo "<h1>User Namespace Test</h1>" > /usr/share/nginx/html/test.html'
+
+# Verify access
+curl http://localhost:8080/test.html
+
+# Check logs
+docker logs test-nginx
+```
+
+#### Test Scenario 2: Database Container (mailcow preparation)
+
+```bash
+# Deploy MariaDB with volume
+docker run -d --name test-db \
+  -e MYSQL_ROOT_PASSWORD=testpass123 \
+  -v mysql-data:/var/lib/mysql \
+  mariadb:10.11
+
+# Wait for startup
+sleep 30
+
+# Test database
+docker exec test-db mysql -ptest pass123 -e "SHOW DATABASES;"
+
+# Create test database
+docker exec test-db mysql -ptest pass123 -e "CREATE DATABASE testdb;"
+
+# Stop and restart to test persistence
+docker stop test-db
+docker start test-db
+sleep 20
+
+# Verify data persisted
+docker exec test-db mysql -ptest pass123 -e "SHOW DATABASES;" | grep testdb
+```
+
+#### Test Scenario 3: Application with File Uploads
+
+```bash
+# Create upload directory
+mkdir -p /tmp/test-uploads
+
+# Run container with bind mount
+docker run -d --name test-upload \
+  -v /tmp/test-uploads:/uploads \
+  alpine:latest sleep infinity
+
+# Test file creation
+docker exec test-upload sh -c 'echo "test" > /uploads/test.txt'
+
+# Check host permissions
+ls -la /tmp/test-uploads/
+# File should be owned by UID 165536
+
+# Test file access from container
+docker exec test-upload cat /uploads/test.txt
+```
+
+### Phase 4: Identify Issues (Week 48-49)
+
+#### Common Issues to Check
+
+1. **Permission Denied Errors**
+   ```bash
+   # Check container logs
+   docker logs <container_name> 2>&1 | grep -i "permission"
+   ```
+
+2. **Volume Mount Failures**
+   ```bash
+   # List volumes
+   docker volume ls
+
+   # Inspect volume
+   docker volume inspect <volume_name>
+
+   # Check actual location on disk
+   sudo ls -la /var/lib/docker/*/volumes/
+   ```
+
+3. **Bind Mount Issues**
+   ```bash
+   # For bind mounts, may need to adjust host permissions
+   # Example: Allow remapped UID to write
+   sudo chown 165536:165536 /path/to/host/dir
+   ```
+
+4. **Privileged Container Conflicts**
+   ```bash
+   # Test if privileged containers still work
+   docker run --rm --privileged alpine:latest id
+   # Note: Privileged containers bypass userns remapping
+   ```

+## Production Implementation (Week 50)
+
+### Implementation Order
+
+1. **pihole** (Week 49 end / Week 50 start) - Lowest risk
+2. **mymx** (Week 50 end) - Highest risk, requires mailcow-specific testing
+
+### pihole Implementation
+
+**Prerequisites:**
+- ✅ Testing completed successfully on derp/test environment
+- ✅ VM snapshot created
+- ✅ Maintenance window scheduled
+- ✅ Rollback procedure reviewed
+
+**Steps:**
+
+```bash
+# 1. Create snapshot
+ansible-playbook playbooks/backup_vm_snapshot.yml \
+  -e "target_vms=['pihole']" \
+  -e "snapshot_description='Pre user namespace implementation'"
+
+# 2. Backup current configuration
+ansible pihole -m shell -a "sudo cp /etc/docker/daemon.json /etc/docker/daemon.json.backup.$(date +%s)" -b
+
+# 3. Stop pihole container
+ansible pihole -m shell -a "docker stop pihole" -b
+
+# 4. Configure user namespace remapping
+ansible pihole -m copy -b -a "
+  dest=/etc/docker/daemon.json
+  content='{\"userns-remap\": \"default\"}'
+  owner=root
+  group=root
+  mode='0644'
+"
+
+# 5. Restart Docker
+ansible pihole -m systemd -a "name=docker state=restarted" -b
+
+# 6. Verify Docker started
+ansible pihole -m shell -a "docker info | grep -i userns" -b
+
+# 7. Recreate pihole container (adjust based on actual deployment)
+# If using docker run command, re-run it
+# If using docker-compose, run: docker-compose up -d
+
+# 8. Verify pihole is working
+ansible pihole -m shell -a "docker ps" -b
+ansible pihole -m shell -a "docker logs pihole --tail 50" -b
+
+# 9. Test DNS functionality
+dig @192.168.122.12 google.com
+
+# 10. Monitor for 1 hour
+watch -n 60 'ansible pihole -m shell -a "docker ps" -b'
+```
+
+**Rollback if Issues:**
+```bash
+# Follow docs/runbooks/docker-configuration-rollback.md
+# Procedure 3: User Namespace Remapping Rollback
+```
+
+---
+
+## Mailcow-Specific Considerations
+
+### Why Mailcow is Complex
+
+1. **Multiple interconnected containers** (24 containers)
+2. **Persistent data in multiple volumes** (mail, databases, configs)
+3. **File permissions critical** for mail delivery
+4. **Active production service** - downtime impact high
+
+### Mailcow Testing Approach (Week 49-50)
+
+#### Phase 1: Research (Week 49)
+
+```bash
+# 1. Check mailcow documentation
+# Search: "user namespace" or "userns-remap"
+# URL: https://docs.mailcow.email/
+
+# 2. Check mailcow GitHub issues
+# Search for: userns, user namespace, permission issues
+
+# 3. Check mailcow community forum
+# URL: https://community.mailcow.email/
+# Search for similar implementations
+```
+
+#### Phase 2: Mailcow Test Environment (Week 49)
+
+**Option A: Deploy test mailcow on derp**
+
+```bash
+# Requires:
+# - 4GB+ RAM (derp may be too small)
+# - 20GB+ disk space
+# - Domain for testing
+
+# Install mailcow on derp
+git clone https://github.com/mailcow/mailcow-dockerized
+cd mailcow-dockerized
+./generate_config.sh
+docker-compose up -d
+```
+
+**Option B: Clone mymx mailcow config to test environment**
+
+```bash
+# Create test VM clone
+# Copy mailcow configuration
+# Test with user namespaces
+```
+
+#### Phase 3: Mailcow Volume Analysis (Week 49)
+
+```bash
+# On mymx, identify all volumes
+docker volume ls | grep mailcow
+
+# Check critical volumes
+docker volume inspect mailcowdockerized_vmail-vol-1
+docker volume inspect mailcowdockerized_mysql-vol-1
+
+# Document current permissions
+for vol in $(docker volume ls -q | grep mailcow); do
+  echo "=== $vol ==="
+  sudo ls -la /var/lib/docker/volumes/$vol/_data/ | head -20
+done > /tmp/mailcow-permissions-before.txt
+```
+
+#### Phase 4: Mailcow Implementation (Week 50 - IF testing successful)
+
+**ONLY proceed if:**
+- ✅ Testing in dev environment successful
+- ✅ pihole implementation successful
+- ✅ Mailcow community confirms no known issues
+- ✅ Extended maintenance window available (2-4 hours)
+- ✅ Full backups completed
+- ✅ Rollback tested and confirmed working
+
+**Implementation Steps:**
+
+```bash
+# 1. Create snapshot
+ansible-playbook playbooks/backup_vm_snapshot.yml \
+  -e "target_vms=['mymx']" \
+  -e "snapshot_description='Pre mailcow user namespace'"
+
+# 2. Backup ALL mailcow data
+ansible mymx -m shell -a "cd /opt/mailcow-dockerized && ./helper-scripts/backup_and_restore.sh backup all" -b
+
+# 3. Stop mailcow
+ansible mymx -m shell -a "cd /opt/mailcow-dockerized && docker-compose down" -b
+
+# 4. Backup current state
+ansible mymx -m shell -a "
+  sudo tar -czf /root/mailcow-pre-userns-$(date +%s).tar.gz \
+    /etc/docker \
+    /opt/mailcow-dockerized \
+    /var/lib/docker/volumes/mailcow*
+" -b
+
+# 5. Configure user namespace
+ansible mymx -m shell -a "
+  sudo cp /etc/docker/daemon.json /etc/docker/daemon.json.backup.$(date +%s)
+  echo '{\"userns-remap\": \"default\"}' | sudo tee /etc/docker/daemon.json
+" -b
+
+# 6. Restart Docker
+ansible mymx -m systemd -a "name=docker state=restarted" -b
+
+# 7. Verify Docker started with user namespaces
+ansible mymx -m shell -a "docker info | grep -i userns" -b
+
+# 8. Start mailcow (will recreate all containers)
+ansible mymx -m shell -a "cd /opt/mailcow-dockerized && docker-compose up -d" -b
+
+# 9. Monitor startup
+watch -n 10 'ansible mymx -m shell -a "cd /opt/mailcow-dockerized && docker-compose ps" -b'
+
+# 10. Check logs for permission errors
+ansible mymx -m shell -a "cd /opt/mailcow-dockerized && docker-compose logs --tail 100" -b | grep -i "permission\|denied\|failed"
+
+# 11. Test mail functionality
+# - Send test email
+# - Receive test email
+# - Check webmail access
+# - Verify SOGo groupware
+# - Test IMAP/SMTP connections
+
+# 12. Monitor for 4-8 hours before declaring success
+```
+
+**Known Potential Issues with Mailcow:**
+
+1. **Vmail Volume Permissions**
+   ```bash
+   # If mail delivery fails with permission errors
+   # May need to adjust permissions (LAST RESORT)
+   sudo chown -R 165536:165536 /var/lib/docker/165536.165536/volumes/mailcowdockerized_vmail-vol-1/_data/
+   ```
+
+2. **MySQL Volume Issues**
+   ```bash
+   # If database won't start
+   # Check MySQL logs
+   docker logs mailcowdockerized-mysql-mailcow-1
+
+   # May need database permission fixes
+   # This is why testing is CRITICAL
+   ```
+
+3. **Dovecot Permission Issues**
+   ```bash
+   # Dovecot is sensitive to mail file permissions
+   # May require config adjustments in mailcow.conf
+   ```
+
+### Mailcow Rollback Decision Point
+
+**Roll back immediately if:**
+- Docker daemon won't start
+- MySQL container won't start
+- Cannot send/receive mail after 15 minutes
+- Permission errors in critical containers
+- Data appears missing/inaccessible
+
+**Use VM snapshot restore if:**
+- Multiple containers failing
+- Data corruption suspected
+- Cannot resolve within 30 minutes
+
+---
+
+## Troubleshooting
+
+### Issue 1: Docker Daemon Won't Start
+
+**Symptoms:**
+```bash
+systemctl status docker
+# Failed to start Docker Application Container Engine
+```
+
+**Solutions:**
+```bash
+# Check logs
+journalctl -u docker -n 100 --no-pager
+
+# Common causes:
+# 1. Invalid daemon.json syntax
+cat /etc/docker/daemon.json | jq '.'
+
+# 2. Subuid/subgid not configured
+cat /etc/subuid
+cat /etc/subgid
+# Should have dockremap:165536:65536
+
+# 3. Restore backup
+sudo cp /etc/docker/daemon.json.backup.<timestamp> /etc/docker/daemon.json
+sudo systemctl start docker
+```
+
+### Issue 2: Container Won't Start - Permission Denied
+
+**Symptoms:**
+```bash
+docker logs <container>
+# Permission denied errors
+```
+
+**Solutions:**
+```bash
+# 1. Check volume location
+docker volume inspect <volume_name>
+
+# 2. Check permissions on host
+sudo ls -la /var/lib/docker/165536.165536/volumes/<volume>/_data/
+
+# 3. If permissions wrong, may need to adjust
+# (Avoid this if possible - indicates larger problem)
+sudo chown -R 165536:165536 /var/lib/docker/165536.165536/volumes/<volume>/_data/
+```
+
+### Issue 3: Bind Mounts Not Working
+
+**Symptoms:**
+```bash
+docker logs <container>
+# Cannot access /bind/mount/path
+```
+
+**Solutions:**
+```bash
+# Bind mounts need host directory permissions adjusted
+sudo chown 165536:165536 /path/to/bind/mount
+
+# Or use volumes instead of bind mounts
+# Volumes are handled automatically by Docker
+```
+
+### Issue 4: Privileged Container Needed
+
+**Note:** Privileged containers (like mailcow netfilter) bypass user namespace remapping.
+
+```bash
+# Verify privileged container still works
+docker inspect <container> | grep -i privileged
+# Should show: "Privileged": true
+
+# Privileged containers run as actual root (userns bypassed)
+# This is expected for netfilter, acceptable risk (documented)
+```
+
+---

+## Overview
+
+This runbook provides step-by-step rollback procedures for Docker configuration changes, with special focus on high-risk modifications like user namespace remapping.
+
+### Risk Classification
+
+| Change Type | Risk Level | Rollback Complexity | Downtime |
+|-------------|-----------|---------------------|----------|
+| Resource limits | LOW | Simple | < 1 min |
+| Image version pinning | LOW | Simple | < 1 min |
+| User namespace remapping | HIGH | Complex | 5-15 min |
+| Network configuration | MEDIUM | Moderate | 2-5 min |
+| Storage driver change | CRITICAL | Complex | 15-30 min |
+
+---
+
+## Pre-Change Requirements
+
+### Before ANY Docker Configuration Change
+
+**MANDATORY STEPS - DO NOT SKIP:**
+
+1. **Create VM Snapshot**
+   ```bash
+   # From Ansible control node
+   ansible-playbook playbooks/backup_vm_snapshot.yml \
+     -e "target_vms=['pihole']" \
+     -e "snapshot_description='Pre Docker config change'"
+   ```
+
+2. **Backup Docker Configuration**
+   ```bash
+   # On target host
+   sudo cp /etc/docker/daemon.json /etc/docker/daemon.json.backup.$(date +%s)
+   sudo tar -czf /root/docker-backup-$(date +%s).tar.gz \
+     /etc/docker \
+     /var/lib/docker/volumes
+   ```
+
+3. **Document Current State**
+   ```bash
+   # Capture current container list
+   docker ps -a --format "table {{.Names}}\t{{.Image}}\t{{.Status}}" > /tmp/containers-before.txt
+
+   # Capture current configuration
+   docker info > /tmp/docker-info-before.txt
+
+   # Capture volume list
+   docker volume ls > /tmp/volumes-before.txt
+   ```
+
+4. **Verify Connectivity**
+   ```bash
+   # Test from Ansible control node
+   ansible pihole -m ping
+   ansible pihole -m shell -a "docker ps"
+   ```
+
+5. **Schedule Maintenance Window**
+   - Notify stakeholders
+   - Plan for 30-60 minute window
+   - Have second person available for verification
+
+---
+
+## Rollback Procedures
+
+### Procedure 1: Quick Rollback (Resource Limits / Image Versions)
+
+**Time Estimate:** 1-2 minutes
+**Risk:** LOW
+**Downtime:** < 1 minute per container
+
+#### Steps
+
+1. **Stop affected container**
+   ```bash
+   docker stop <container_name>
+   ```
+
+2. **Restore previous configuration**
+   ```bash
+   # For docker run commands
+   # Simply re-run with old parameters
+
+   # For docker-compose
+   git checkout HEAD~1 docker-compose.yml
+   docker-compose up -d <container_name>
+   ```
+
+3. **Verify service**
+   ```bash
+   docker ps | grep <container_name>
+   docker logs <container_name> --tail 50
+
+   # Test application functionality
+   curl -I http://<service_url>
+   ```
+
+#### Success Criteria
+- Container running
+- Logs show normal operation
+- Service accessible
+- No errors in `docker logs`
+
+---
+
+### Procedure 2: Daemon Configuration Rollback (Non-Breaking Changes)
+
+**Time Estimate:** 3-5 minutes
+**Risk:** MEDIUM
+**Downtime:** 2-3 minutes
+
+#### Steps
+
+1. **Restore daemon.json**
+   ```bash
+   sudo cp /etc/docker/daemon.json.backup.<timestamp> /etc/docker/daemon.json
+   ```
+
+2. **Restart Docker daemon**
+   ```bash
+   sudo systemctl restart docker
+   ```
+
+3. **Verify Docker is running**
+   ```bash
+   sudo systemctl status docker
+   docker info
+   ```
+
+4. **Check all containers**
+   ```bash
+   docker ps -a
+
+   # Restart any stopped containers
+   docker start $(docker ps -aq)
+   ```
+
+5. **Verify services**
+   ```bash
+   # Test each service
+   docker logs <container> --tail 20
+   ```
+
+#### Success Criteria
+- Docker daemon running
+- All containers started
+- Services accessible
+- No errors in `journalctl -u docker`
+
+---
+
+### Procedure 3: User Namespace Remapping Rollback (HIGH RISK)
+
+**Time Estimate:** 10-15 minutes
+**Risk:** HIGH
+**Downtime:** 10-15 minutes
+**Data Loss Risk:** LOW (if volumes backed up)
+
+⚠️ **WARNING:** This is the most complex rollback. Follow carefully.
+
+#### Pre-Rollback Verification
+
+```bash
+# Verify snapshot exists
+ssh grokbox "sudo virsh snapshot-list <vm_name>"
+
+# Verify backup archive exists
+ls -lh /root/docker-backup-*.tar.gz
+```
+
+#### Steps
+
+1. **Stop all containers gracefully**
+   ```bash
+   # Mailcow example
+   cd /opt/mailcow-dockerized
+   docker-compose down
+
+   # Or generic
+   docker stop $(docker ps -q)
+   ```
+
+2. **Stop Docker daemon**
+   ```bash
+   sudo systemctl stop docker
+   ```
+
+3. **Restore daemon.json (remove userns-remap)**
+   ```bash
+   sudo cp /etc/docker/daemon.json.backup.<timestamp> /etc/docker/daemon.json
+
+   # Verify userns-remap is removed
+   grep -i userns /etc/docker/daemon.json
+   ```
+
+4. **CRITICAL: Handle user namespace volume mappings**
+   ```bash
+   # User namespaced volumes are in a different location
+   # /var/lib/docker/<uid>.<gid>/volumes/
+
+   # List namespaced volumes
+   sudo ls -la /var/lib/docker/*/volumes/
+
+   # Copy volumes back to main location (if needed)
+   sudo rsync -av /var/lib/docker/*/volumes/* /var/lib/docker/volumes/
+   ```
+
+5. **Start Docker daemon**
+   ```bash
+   sudo systemctl start docker
+   sudo systemctl status docker
+   ```
+
+6. **Verify Docker info**
+   ```bash
+   docker info | grep -i "userns"
+   # Should NOT show user namespace remapping
+   ```
+
+7. **Recreate containers**
+   ```bash
+   # Mailcow example
+   cd /opt/mailcow-dockerized
+   docker-compose up -d
+
+   # Wait for all containers to start
+   watch -n 2 'docker ps --format "table {{.Names}}\t{{.Status}}"'
+   ```
+
+8. **Verify all services**
+   ```bash
+   # Check container logs
+   docker-compose logs --tail 50
+
+   # Test services
+   curl -I https://cow.mymx.me
+
+   # Verify email functionality (mailcow)
+   docker-compose exec postfix-mailcow postqueue -p
+   ```
+
+#### If Rollback Fails: VM Snapshot Restore
+
+```bash
+# From Ansible control node or directly on hypervisor
+
+# 1. Shutdown VM
+ssh grokbox "sudo virsh shutdown <vm_name>"
+
+# 2. Wait for shutdown (max 60 seconds)
+sleep 30
+
+# 3. Force stop if needed
+ssh grokbox "sudo virsh destroy <vm_name>"
+
+# 4. Revert to snapshot
+ssh grokbox "sudo virsh snapshot-revert <vm_name> backup_<timestamp>"
+
+# 5. Start VM
+ssh grokbox "sudo virsh start <vm_name>"
+
+# 6. Verify SSH access (may take 1-2 minutes)
+ansible <vm_name> -m ping
+
+# 7. Verify services
+ansible <vm_name> -m shell -a "docker ps"
+```
+
+#### Success Criteria
+- Docker daemon running WITHOUT user namespace remapping
+- All containers running
+- All services accessible
+- Volume data intact
+- No permission errors in logs
+
+---
+
+## Specific Scenarios
+
+### Scenario A: Mailcow Container Won't Start After Namespace Change
+
+**Symptoms:**
+- Containers exit immediately
+- Permission denied errors in logs
+- Volume mount failures
+
+**Solution:**
+```bash
+# 1. Check volume permissions
+docker run --rm -v mailcowdockerized_vmail-vol-1:/volume alpine ls -la /volume
+
+# 2. Fix permissions if needed (DANGEROUS - only if you know UID mapping)
+# This example assumes standard userns mapping (165536 offset)
+sudo chown -R 165536:165536 /var/lib/docker/volumes/mailcowdockerized_vmail-vol-1
+
+# 3. If permissions are unfixable, revert to snapshot
+# See "VM Snapshot Restore" above
+```
+
+### Scenario B: Docker Daemon Won't Start After Config Change
+
+**Symptoms:**
+- `systemctl start docker` fails
+- Errors in `journalctl -u docker`
+
+**Solution:**
+```bash
+# 1. Check exact error
+sudo journalctl -u docker -n 50 --no-pager
+
+# 2. Validate daemon.json syntax
+sudo cat /etc/docker/daemon.json | jq '.'
+
+# 3. If syntax error, restore backup
+sudo cp /etc/docker/daemon.json.backup.<timestamp> /etc/docker/daemon.json
+
+# 4. If configuration conflict, check docs
+sudo dockerd --validate --config-file /etc/docker/daemon.json
+
+# 5. Start daemon
+sudo systemctl start docker
+```
+
+### Scenario C: Data Loss After Namespace Change
+
+**Symptoms:**
+- Volumes appear empty
+- Database containers can't find data
+- Application state lost
+
+**Solution:**
+```bash
+# 1. STOP - Do not proceed with data recovery attempts
+# 2. DO NOT restart containers
+# 3. Immediately revert to snapshot
+
+ssh grokbox "sudo virsh snapshot-revert <vm_name> backup_<timestamp>"
+
+# 4. After VM restore, verify data
+docker exec <database_container> <verification_command>
+
+# Example for MySQL
+docker exec mailcowdockerized-mysql-mailcow-1 mysql -u root -p<password> -e "SHOW DATABASES;"
+```

+
+## Testing Rollback Procedures
+
+### Monthly Rollback Drill
+
+**Schedule:** First Monday of each month
+**Duration:** 30 minutes
+**Environment:** Development/Test VMs only
+
+#### Drill Steps
+
+1. **Create test VM or use derp**
+   ```bash
+   # Deploy test container
+   docker run -d --name test-nginx nginx:latest
+   ```
+
+2. **Create snapshot**
+   ```bash
+   ansible-playbook playbooks/backup_vm_snapshot.yml \
+     -e "target_vms=['test-vm']"
+   ```
+
+3. **Make intentional breaking change**
+   ```bash
+   # Break Docker config
+   echo '{"invalid": json}' | sudo tee /etc/docker/daemon.json
+   sudo systemctl restart docker  # This will fail
+   ```
+
+4. **Practice rollback**
+   ```bash
+   # Follow Procedure 2 above
+   sudo cp /etc/docker/daemon.json.backup.<timestamp> /etc/docker/daemon.json
+   sudo systemctl start docker

+
+---
+
+## Preventive Measures
+
+### Before Making High-Risk Changes
+
+1. **Test in development first**
+   - Use derp VM or test environment
+   - Replicate production as closely as possible
+   - Document exact steps that work
+
+2. **Review Docker/Mailcow changelogs**
+   - Check for known issues
+   - Review breaking changes
+   - Search community forums
+
+3. **Peer review change plan**
+   - Have colleague review procedure
+   - Walk through rollback steps
+   - Verify backup procedures
+
+4. **Schedule during low-traffic period**
+   - Weekend or late evening
+   - Notify users in advance
+   - Have monitoring ready
+

+# Docker Security Audit Findings
+
+**Date:** 2025-11-11
+**Audit Tool:** playbooks/audit_docker.yml
+**Audited Hosts:** pihole, mymx
+
+---
+
+## Executive Summary
+
+Docker security audits completed on 2 hosts running containerized services. Total of **25 containers** audited across both hosts.
+
+### Overall Security Posture
+
+| Host | Containers | CRITICAL | HIGH | MEDIUM | LOW | Status |
+|------|-----------|----------|------|--------|-----|--------|
+| **pihole** | 1 | 0 | 0 | 2 | 1 | 🟡 Acceptable |
+| **mymx** | 24 | 1 | 1 | 2 | 1 | 🔴 Needs Review |
+
+---
+
+## Detailed Findings
+
+### pihole (192.168.122.12)
+
+**Docker Version:** 28.3.3
+**Storage Driver:** overlay2
+**Security Options:** apparmor, seccomp, cgroupns
+
+#### Findings Summary
+- ✅ **No privileged containers**
+- ✅ **No host network mode containers**
+- ⚠️ User namespace remapping not configured
+- ⚠️ Containers without resource limits
+- ℹ️ 1 image using :latest tag
+
+#### Recommendations
+1. Enable user namespace remapping in `/etc/docker/daemon.json`
+2. Set memory and CPU limits on pi-hole container
+3. Pin pi-hole image to specific version tag
+
+---
+
+### mymx (192.168.122.119)
+
+**Docker Version:** 28.5.1
+**Storage Driver:** overlay2
+**Security Options:** apparmor, seccomp, cgroupns
+**Application:** Mailcow mail server + additional services
+
+#### Findings Summary
+- 🔴 **1 privileged container** (netfilter)
+- 🟠 **1 host network mode container** (netfilter)
+- ⚠️ User namespace remapping not configured
+- ⚠️ All 24 containers without resource limits
+- ℹ️ 5 images using :latest tag
+
+#### Critical Finding: mailcowdockerized-netfilter-mailcow-1
+
+**Container:** `/mailcowdockerized-netfilter-mailcow-1`
+**Issues:**
+- Privileged mode: `true`
+- Network mode: `host`
+
+**Justification:**
+This container provides network filtering and firewall functionality for the mailcow email infrastructure. It requires:
+- **Privileged mode**: Access to iptables/netfilter for packet filtering
+- **Host network mode**: Direct network stack access for filtering rules
+
+**Risk Assessment:** ⚠️ MEDIUM
+- Container is part of official mailcow deployment
+- Necessary for spam/malware filtering
+- Security hardening applied via mailcow project
+- Container maintained by mailcow developers
+
+**Recommendation:** ✅ ACCEPT with monitoring
+- Document exception in security policy
+- Monitor container for unusual activity
+- Keep mailcow updated to latest stable version
+- Review mailcow security advisories regularly
+- Consider implementing SELinux/AppArmor custom profile
+
+---
+
+## Common Issues Across All Hosts
+
+### 1. User Namespace Remapping (MEDIUM)
+
+**Issue:** Docker daemon not configured with user namespace remapping
+**Impact:** Containers run as root inside container = root on host
+**Risk:** Container escape could lead to full host compromise
+
+**Remediation:**
+```bash
+# Add to /etc/docker/daemon.json
+{
+  "userns-remap": "default"
+}
+
+# Restart Docker
+systemctl restart docker
+
+# Note: Existing containers will need to be recreated
+```
+
+**Considerations:**
+- ⚠️ Breaking change - all containers must be recreated
+- Volume permissions will need adjustment
+- May require mailcow reconfiguration
+- Test in staging environment first
+
+**Priority:** HIGH (plan for Week 48-49 implementation)
+
+---
+
+### 2. Missing Resource Limits (MEDIUM)
+
+**Issue:** Containers have no memory or CPU limits (Memory=0, CPU=0)
+**Impact:** Single container can exhaust host resources
+**Risk:** DoS, resource starvation, noisy neighbor problems
+
+**Remediation for Mailcow:**
+```yaml
+# In mailcow docker-compose.override.yml
+services:
+  postfix-mailcow:
+    deploy:
+      resources:
+        limits:
+          cpus: '2.0'
+          memory: 1G
+        reservations:
+          memory: 512M
+```
+
+**Recommended Limits per Container Type:**
+- **Web/API containers** (nginx, php-fpm): 512M-1G
+- **Database** (mysql): 2G-4G
+- **Mail services** (postfix, dovecot): 1G-2G
+- **Antivirus** (clamd): 2G-4G (memory intensive)
+- **Redis/Memcached**: 256M-512M
+- **Utility containers**: 128M-256M
+
+**Priority:** HIGH (implement in Week 48)
+
+---
+
+### 3. Latest Image Tags (LOW)
+
+**Issue:** 5 images on mymx using `:latest` tag
+**Impact:** Non-reproducible deployments, unexpected updates
+**Risk:** Low - can cause compatibility issues
+
+**Affected Images:**
+- Check with: `docker images | grep latest`
+
+**Remediation:**
+```bash
+# Pin to specific versions in docker-compose.yml
+# Example:
+  redis:
+    image: redis:7.2.3-alpine
+    # instead of: redis:latest
+```
+
+**Priority:** MEDIUM (Week 49)
+
+---
+
+## Remediation Roadmap
+
+### Week 47 (Current) ✅
+- [x] Complete Docker security audits
+- [x] Document findings
+- [x] Identify privileged containers
+- [x] Create remediation plan
+
+### Week 48 (Next Week)
+- [ ] Document netfilter container exception
+- [ ] Implement resource limits on non-critical containers (pihole, utility services)
+- [ ] Pin image versions for pihole and standalone containers
+- [ ] Create backup/restore procedures before changes
+
+### Week 49
+- [ ] Test user namespace remapping in development
+- [ ] Document mailcow migration procedures
+- [ ] Implement resource limits for mailcow containers
+- [ ] Pin all mailcow image versions
+
+### Week 50
+- [ ] Implement user namespace remapping (if tested successfully)
+- [ ] Verify all services operational after changes
+- [ ] Update documentation
+- [ ] Re-run security audits to verify improvements
+
+---
+
+## Compliance Mapping
+
+### CIS Docker Benchmark
+- ✅ **2.1** - AppArmor enabled
+- ✅ **2.8** - Seccomp profiles active
+- ❌ **2.13** - User namespace support not enabled
+- ⚠️ **5.3** - Privileged containers (1 justified exception)
+- ❌ **5.11** - CPU priority not set
+- ❌ **5.12** - Memory limits not set
+- ⚠️ **5.15** - Host network namespace (1 justified exception)
+
+**Compliance Score:**
+- pihole: **70%** (3 of 6 applicable controls)
+- mymx: **58%** (3.5 of 6 applicable controls)
+
+### NIST SP 800-190
+- ✅ **Image security** - Using official images
+- ⚠️ **Registry security** - No private registry
+- ❌ **Runtime protection** - Missing resource limits
+- ⚠️ **Host OS** - User namespaces not configured
+- ✅ **Network isolation** - Most containers use bridge networks
+
+---
+
+## Monitoring & Ongoing Security
+
+### Recommended Actions
+1. **Automated Scanning:** Implement Trivy or Clair for image vulnerability scanning
+2. **Runtime Monitoring:** Deploy Falco for container runtime security
+3. **Log Aggregation:** Forward Docker logs to centralized logging (already have rsyslog)
+4. **Regular Audits:** Run docker audit playbook weekly
+5. **Update Policy:** Review and apply security updates monthly
+
+### Alerting Thresholds
+- New privileged container detected
+- Container CPU > 80% for > 5 minutes
+- Container memory > 90% for > 2 minutes
+- New container using host network mode
+- Image pulls from untrusted registries

+# enabling better VM management from the hypervisor.
+#
+# Benefits of QEMU Guest Agent:
+#   - Accurate IP address discovery from hypervisor
+#   - Filesystem quiescing for consistent snapshots
+#   - Graceful shutdown/reboot from hypervisor
+#   - VM state monitoring and management
+#
+# Usage:

+#   ansible-playbook playbooks/install_qemu_agent.yml --limit pihole
+#
+# Note: After installation, the VM needs a virtio-serial channel configured
+# in the libvirt domain XML. This playbook installs the guest-side component.
+#
+# To add the channel (run on hypervisor):
+#   virsh attach-device <vm-name> --config --file channel.xml
+#
+# Where channel.xml contains:
+#   <channel type='unix'>

+          MANUAL CONFIGURATION REQUIRED
+          =============================
+
+          The QEMU guest agent is installed and running inside this VM, but it cannot
+          communicate with the hypervisor because the virtio-serial channel is not configured.
+
+          To complete the setup, execute these commands ON THE HYPERVISOR:
+
+          1. Shutdown this VM:
+             virsh shutdown {{ inventory_hostname }}
+
+          2. Create channel configuration file:
+             cat > /tmp/{{ inventory_hostname }}-channel.xml << 'EOF'
+             <channel type='unix'>
+               <source mode='bind'/>
+               <target type='virtio' name='org.qemu.guest_agent.0'/>
+             </channel>
+             EOF
+
+          3. Attach the channel to the VM:
+             virsh attach-device {{ inventory_hostname }} \
+               --config --file /tmp/{{ inventory_hostname }}-channel.xml
+
+          4. Start the VM:
+             virsh start {{ inventory_hostname }}
+
+          5. Verify the agent is working:
+             virsh qemu-agent-command {{ inventory_hostname }} '{"execute":"guest-ping"}'
+
+          Alternatively, you can edit the XML directly:
+             virsh edit {{ inventory_hostname }}
+
+          And add this section inside <devices>:
+             <channel type='unix'>
+               <source mode='bind'/>
+               <target type='virtio' name='org.qemu.guest_agent.0'/>
+             </channel>
+          {% else %}
+          CONFIGURATION COMPLETE
+          ======================
+
+          The QEMU guest agent is fully configured and can communicate with the hypervisor.
+
+          Test from hypervisor:
+            virsh qemu-agent-command {{ inventory_hostname }} '{"execute":"guest-ping"}'
+            virsh qemu-agent-command {{ inventory_hostname }} '{"execute":"guest-info"}'

+
+{% endif %}
+
+RECOMMENDATIONS
+========================================
+
+CRITICAL PRIORITY
+----------------------------------------
+{% if container_privileges.stdout is defined and 'Privileged=true' in container_privileges.stdout %}
+1. ⚠️  DISABLE PRIVILEGED MODE
+   - Privileged containers have full access to host resources
+   - Remove --privileged flag unless absolutely necessary
+   - Use specific capabilities (--cap-add) instead
+   - Document justification for any privileged containers
+
+{% endif %}
+{% if network_modes.stdout is defined and 'NetworkMode=host' in network_modes.stdout %}
+2. ⚠️  AVOID HOST NETWORK MODE
+   - Host network mode bypasses Docker network isolation
+   - Use bridge mode and explicit port mappings
+   - Consider using macvlan for performance-critical applications
+
+{% endif %}
+
+HIGH PRIORITY
+----------------------------------------
+3. IMPLEMENT USER NAMESPACE REMAPPING
+   - Add to /etc/docker/daemon.json:
+     {
+       "userns-remap": "default"
+     }
+   - Restart Docker daemon after configuration change
+   - Note: Existing containers will need to be recreated
+
+4. ENFORCE RESOURCE LIMITS
+   - Set memory limits: --memory="512m"
+   - Set CPU limits: --cpus="1.0"
+   - Prevents container resource exhaustion attacks
+   - Example:
+     docker run --memory="512m" --cpus="1.0" image:tag
+
+5. USE SECURITY PROFILES
+   - Enable AppArmor (Debian/Ubuntu):
+     --security-opt apparmor=docker-default
+   - Enable SELinux (RHEL/CentOS):
+     --security-opt label=type:container_t
+   - Create custom profiles for sensitive containers
+
+MEDIUM PRIORITY
+----------------------------------------
+6. DROP UNNECESSARY CAPABILITIES
+   - Drop all by default: --cap-drop=ALL
+   - Add only required capabilities:
+     --cap-add=NET_BIND_SERVICE (for ports < 1024)
+     --cap-add=CHOWN (for ownership changes)
+   - Never use --cap-add=ALL
+
+7. USE SPECIFIC IMAGE TAGS
+   - Replace :latest with specific version tags
+   - Ensures reproducible deployments
+   - Facilitates rollback procedures
+   - Example: nginx:1.25.3-alpine instead of nginx:latest
+
+8. MINIMIZE EXPOSED PORTS
+   - Only expose necessary ports
+   - Use internal networks for container-to-container communication
+   - Consider using reverse proxy (Traefik, nginx) for public access
+
+9. IMPLEMENT READ-ONLY ROOT FILESYSTEMS
+   - Use --read-only flag when possible
+   - Mount tmpfs for writable directories:
+     --tmpfs /tmp --tmpfs /var/run
+
+10. ENABLE DOCKER CONTENT TRUST
+    - Set environment variable:
+      export DOCKER_CONTENT_TRUST=1
+    - Ensures images are signed and verified
+    - Prevents use of tampered images
+
+LOW PRIORITY
+----------------------------------------
+11. REGULAR IMAGE UPDATES
+    - Schedule regular image pulls and container recreation
+    - Subscribe to security advisories for base images
+    - Consider using automated tools: Watchtower, Renovate
+
+12. IMPLEMENT LOGGING
+    - Configure centralized logging
+    - Use logging drivers: syslog, json-file, etc.
+    - Set log rotation limits to prevent disk exhaustion
+
+13. NETWORK SEGMENTATION
+    - Create separate networks for different application tiers
+    - Use internal networks for backend services
+    - Implement network policies where supported
+
+COMPLIANCE CHECKLIST
+========================================
+
+CIS Docker Benchmark Alignment:
+[ ] 2.1 - Run daemon as non-root user (user namespace remapping)
+[ ] 2.2 - Set default ulimit as appropriate
+[ ] 2.13 - Enable user namespace support
+[ ] 5.1 - Do not disable AppArmor/SELinux profile
+[ ] 5.3 - Do not use privileged containers
+[ ] 5.7 - Do not map privileged ports within containers
+[ ] 5.12 - Mount container's root filesystem as read only
+[ ] 5.15 - Do not share the host's network namespace
+[ ] 5.25 - Restrict container from acquiring additional privileges
+[ ] 5.28 - Use PIDs cgroup limit
+
+NIST 800-190 Guidelines:
+[ ] Image security and integrity
