| `deploy_linux_vm_root_password` | (vault variable) | Root password (console access) |
**SECURITY NOTICE**: SSH keys and passwords should be stored in encrypted vault files, not in defaults.
## Security Best Practices
### Secrets Management
This role requires sensitive data (SSH keys, passwords) to be stored securely:
#### Option 1: Ansible Vault (Recommended for Small/Medium Deployments)
1. Create a vault file in your inventory:
```bash
# Create encrypted vault file
ansible-vault create inventories/production/group_vars/all/vault.yml
```
2. Add the required vault variables:
```yaml
---
# SSH public key for ansible user
vault_deploy_linux_vm_ansible_user_ssh_key: "ssh-ed25519 AAAAC3... ansible@automation"
# Root password for emergency console access
vault_deploy_linux_vm_root_password: "YourSecurePassword123!"
```
3. Reference vault variables in your playbook or group_vars:
```yaml
# inventories/production/group_vars/all/vars.yml
deploy_linux_vm_ansible_user_ssh_key: "{{ vault_deploy_linux_vm_ansible_user_ssh_key }}"
deploy_linux_vm_root_password: "{{ vault_deploy_linux_vm_root_password }}"
```
4. Run playbooks with vault password:
```bash
ansible-playbook site.yml --ask-vault-pass
# Or use a password file
ansible-playbook site.yml --vault-password-file ~/.vault_pass
```
#### Option 2: External Secret Managers (Recommended for Enterprise)
- **HashiCorp Vault**: Use `community.hashi_vault.vault_read` lookup plugin
- **AWS Secrets Manager**: Use `amazon.aws.aws_secret` lookup plugin
- **Azure Key Vault**: Use `azure.azcollection.azure_keyvault_secret` lookup plugin
- **CyberArk**: Use CyberArk Ansible plugins
Example with HashiCorp Vault:
```yaml
deploy_linux_vm_ansible_user_ssh_key: "{{ lookup('community.hashi_vault.vault_read', 'secret/data/ansible/ssh_key').data.public_key }}"
```
#### Option 3: Environment Variables
```bash
export ANSIBLE_VAULT_PASSWORD_FILE=~/.vault_pass
export DEPLOY_VM_SSH_KEY="ssh-ed25519 AAAAC3..."
```
```yaml
deploy_linux_vm_ansible_user_ssh_key: "{{ lookup('env', 'DEPLOY_VM_SSH_KEY') }}"
```
### SSH Key Generation
Generate a dedicated SSH key pair for VM deployment:
```bash
# Generate ED25519 key (recommended)
ssh-keygen -t ed25519 -C "ansible-automation" -f ~/.ssh/ansible_deploy
# Or RSA 4096-bit key
ssh-keygen -t rsa -b 4096 -C "ansible-automation" -f ~/.ssh/ansible_deploy
# Use the public key in your vault file
cat ~/.ssh/ansible_deploy.pub
```
### Password Generation
Generate strong root passwords:
```bash
# Using OpenSSL
openssl rand -base64 32
# Using pwgen
pwgen -s 32 1
# Using /dev/urandom
tr -dc 'A-Za-z0-9!@#$%^&*' < /dev/urandom | head -c 32
```
### Security Checklist
- [ ] SSH keys stored in Ansible Vault or external secret manager
- [ ] Root passwords stored in Ansible Vault (different per environment)
- [ ] Vault password file has restricted permissions (0600)
- [ ] Vault password file is NOT committed to version control (in .gitignore)
- [ ] Different passwords used for dev/staging/production
- [ ] SSH keys rotated every 90-180 days
- [ ] Regular security audits performed

# This file shows the structure for vault-encrypted variables.
#
# SECURITY INSTRUCTIONS:
# 1. Copy this file to your secrets directory or group_vars/all/vault.yml
# 2. Update the values with your actual secrets
# 3. Encrypt the file using ansible-vault:
# ansible-vault encrypt group_vars/all/vault.yml
# 4. NEVER commit unencrypted secrets to version control
#
# Alternative: Use external secret managers:
# - HashiCorp Vault
# - AWS Secrets Manager
# - Azure Key Vault
# - CyberArk
