+# Ansible Vault Management Guide
+
+This document describes how to manage encrypted secrets using Ansible Vault in this infrastructure.
+
+## Overview
+
+Ansible Vault is used to encrypt sensitive data such as passwords, API tokens, and private keys. All vault files are stored in `inventories/<environment>/group_vars/all/vault.yml`.

+
+## Quick Start
+
+```bash
+# 1. Create vault file from example
+cp inventories/production/group_vars/all/vault.yml.example \
+   inventories/production/group_vars/all/vault.yml
+
+# 2. Edit and fill in secrets
+vi inventories/production/group_vars/all/vault.yml
+
+# 3. Encrypt the vault file
+ansible-vault encrypt inventories/production/group_vars/all/vault.yml
+
+# 4. Run playbook with vault password
+ansible-playbook site.yml --ask-vault-pass
+```
+
+## Vault File Locations
+
+Vault files are organized by environment:
+
+```
+inventories/
+├── production/
+│   └── group_vars/
+│       └── all/
+│           ├── vault.yml.example  # Template
+│           └── vault.yml          # Encrypted (gitignored)
+├── staging/
+│   └── group_vars/
+│       └── all/
+│           ├── vault.yml.example
+│           └── vault.yml
+└── development/
+    └── group_vars/
+        └── all/
+            ├── vault.yml.example
+            └── vault.yml
+```
+
+**Important**: `vault.yml` files should be added to `.gitignore` to prevent accidental commits.
+
+## Creating Vault Files
+
+### From Example Template
+
+```bash
+# Copy example template
+cp inventories/production/group_vars/all/vault.yml.example \
+   inventories/production/group_vars/all/vault.yml
+
+# Edit and replace CHANGEME placeholders
+vi inventories/production/group_vars/all/vault.yml
+
+# Encrypt the file
+ansible-vault encrypt inventories/production/group_vars/all/vault.yml
+```
+
+### Create New Vault File
+
+```bash
+# Create and encrypt in one step
+ansible-vault create inventories/production/group_vars/all/vault.yml
+```
+
+This opens your editor to add vault contents, then automatically encrypts on save.
+
+## Encrypting and Decrypting
+
+### Encrypt a File
+
+```bash
+ansible-vault encrypt inventories/production/group_vars/all/vault.yml
+```
+
+You'll be prompted to create a vault password.
+
+### Decrypt a File
+
+```bash
+# Decrypt to view/edit (dangerous - creates plaintext file)
+ansible-vault decrypt inventories/production/group_vars/all/vault.yml
+
+# View without decrypting
+ansible-vault view inventories/production/group_vars/all/vault.yml
+```
+
+**Warning**: Decrypting a file leaves it in plaintext. Always re-encrypt after editing.
+
+### Encrypt Multiple Files
+
+```bash
+ansible-vault encrypt inventories/*/group_vars/all/vault.yml
+```
+
+## Editing Vault Files
+
+### Edit Encrypted File
+
+```bash
+# Edit encrypted file directly (recommended)
+ansible-vault edit inventories/production/group_vars/all/vault.yml
+```
+
+This decrypts the file in memory, opens your editor, and re-encrypts on save.
+
+### Change Vault Password
+
+```bash
+ansible-vault rekey inventories/production/group_vars/all/vault.yml
+```
+
+You'll be prompted for the old password, then the new password.
+
+## Using Vault Variables
+
+### In Playbooks
+
+Reference vault variables like normal variables:
+
+```yaml
+---
+- name: Configure database
+  hosts: databases
+  tasks:
+    - name: Set MySQL root password
+      mysql_user:
+        name: root
+        password: "{{ vault_mysql_root_password }}"
+        host: localhost
+```
+
+### In Templates
+
+```jinja2
+# /etc/my.cnf
+[client]
+user = root
+password = {{ vault_mysql_root_password }}
+```
+
+### In Role Defaults
+
+```yaml
+# roles/mysql/defaults/main.yml
+---
+mysql_root_password: "{{ vault_mysql_root_password }}"
+```
+
+## Vault Password Management
+
+### Option 1: Interactive Password Prompt (Most Secure)
+
+```bash
+ansible-playbook site.yml --ask-vault-pass
+```
+
+### Option 2: Password File
+
+Create a password file:
+
+```bash
+# Create password file (gitignored)
+echo "YourVaultPassword123!" > .vault_pass
+chmod 600 .vault_pass
+```
+
+Add to `.gitignore`:
+```
+.vault_pass
+```
+
+Update `ansible.cfg`:
+```ini
+[defaults]
+vault_password_file = .vault_pass
+```
+
+Run playbooks without prompt:
+```bash
+ansible-playbook site.yml
+```
+
+### Option 3: Environment Variable
+
+```bash
+export ANSIBLE_VAULT_PASSWORD_FILE=.vault_pass
+ansible-playbook site.yml
+```
+
+### Option 4: Script-Based Password (Advanced)
+
+Create a script that retrieves the password from a secure source:
+
+```bash
+#!/bin/bash
+# vault-password.sh
+# Retrieve password from AWS Secrets Manager, HashiCorp Vault, etc.
+aws secretsmanager get-secret-value \
+  --secret-id ansible-vault-password \
+  --query SecretString \
+  --output text
+```
+
+Make it executable:
+```bash
+chmod +x vault-password.sh
+```
+
+Use in `ansible.cfg`:
+```ini
+[defaults]
+vault_password_file = ./vault-password.sh
+```
+
+## Best Practices
+
+### Security
+
+1. **Never commit unencrypted vault files** to version control
+2. **Use different vault passwords** for each environment
+3. **Rotate vault passwords** every 90 days
+4. **Restrict access** to vault password files (`chmod 600`)
+5. **Use strong passwords** (minimum 20 characters, mixed case, numbers, symbols)
+6. **Store production passwords** in a secure password manager (1Password, LastPass, etc.)
+
+### Organization
+
+1. **Prefix vault variables** with `vault_` for clarity:
+   ```yaml
+   vault_mysql_root_password: "secret123"
+   vault_api_token: "token456"
+   ```
+
+2. **Use vault variables in role defaults**:
+   ```yaml
+   # roles/mysql/defaults/main.yml
+   mysql_root_password: "{{ vault_mysql_root_password }}"
+   ```
+
+3. **Document all vault variables** in `vault.yml.example`
+
+4. **One vault file per environment** for easier management
+
+### Git Management
+
+Add to `.gitignore`:
+```
+# Vault passwords
+.vault_pass
+vault-password.sh
+
+# Unencrypted vault files
+**/vault.yml
+!**/vault.yml.example
+```
+
+Verify vault files are encrypted before committing:
+```bash
+# Check if file is encrypted
+head -1 inventories/production/group_vars/all/vault.yml
+# Should output: $ANSIBLE_VAULT;1.1;AES256
+```
+
+## Multiple Vault Passwords
+
+For environments with different vault passwords:
+
+### Using Vault IDs
+
+```bash
+# Encrypt with vault ID
+ansible-vault encrypt \
+  --vault-id production@prompt \
+  inventories/production/group_vars/all/vault.yml
+
+ansible-vault encrypt \
+  --vault-id staging@prompt \
+  inventories/staging/group_vars/all/vault.yml
+
+# Run playbook with multiple vault IDs
+ansible-playbook site.yml \
+  --vault-id production@.vault_pass_production \
+  --vault-id staging@.vault_pass_staging
+```
+
+## Common Vault Variables
+
+### User Credentials
+```yaml
+vault_ansible_user_ssh_key: "ssh-rsa AAAA..."
+vault_root_password: "password"
+vault_ansible_become_password: "password"
+```
+
+### API Tokens
+```yaml
+vault_aws_access_key_id: "AKIA..."
+vault_aws_secret_access_key: "secret"
+vault_netbox_api_token: "token"
+```
+
+### Database Credentials
+```yaml
+vault_mysql_root_password: "password"
+vault_postgresql_postgres_password: "password"
+```
+
+### Application Secrets
+```yaml
+vault_app_secret_key: "secret_key"
+vault_app_api_key: "api_key"
+```
+
+## Troubleshooting
+
+### Wrong Vault Password
+
+**Error**: `Decryption failed (no vault secrets were found that could decrypt)`
+
+**Solution**: Verify you're using the correct vault password for that environment.
+
+### Vault File Not Found
+
+**Error**: `ERROR! Attempting to decrypt but no vault secrets found`
+
+**Solution**: Create the vault file or check the path is correct.
+
+### Permission Denied
+
+**Error**: `Permission denied: 'vault.yml'`
+
+**Solution**: Check file permissions:
+```bash
+ls -la inventories/production/group_vars/all/vault.yml
+chmod 600 inventories/production/group_vars/all/vault.yml
+```
+
+### Forgot Vault Password
+
+**Solution**: Unfortunately, there's no way to recover a forgotten vault password. You'll need to:
+1. Re-create the vault file from scratch
+2. Re-enter all secrets
+3. Re-encrypt with a new password
+
+**Prevention**: Store vault passwords in a secure password manager.
+
+### Check Vault File Integrity
+
+```bash
+# Verify file can be decrypted
+ansible-vault view inventories/production/group_vars/all/vault.yml
+
+# Check encryption format
+file inventories/production/group_vars/all/vault.yml
+# Should output: ASCII text (encrypted vault file)
+```
+
+## Emergency Procedures
+
+### Compromised Vault Password
+
+1. **Immediately change the vault password**:
+   ```bash
+   ansible-vault rekey inventories/production/group_vars/all/vault.yml
+   ```
+
+2. **Rotate all secrets** stored in the vault
+
+3. **Audit access logs** to determine scope of compromise
+
+4. **Update vault password** in all secure storage locations
+
+### Lost Access to Production Vault
+
+1. Use backup vault password from secure password manager
+2. If no backup exists, rotate all production credentials
+3. Create new vault file with new credentials
+4. Update all systems with new credentials
