# Azure-init x Afterburn integration 🔥 

1. **Metadata Retrieval**  
   - Implement retrieval of metadata from Azure's Instance Metadata Service (IMDS)
   - Fetch instance details, network settings, SSH keys, and custom data
   - Ensure secure and efficient data handling

2. **SSH Key Management**
   - Support key retrieval from IMDS and proper configuration
   - Implement key injection with correct permissions
   - Add support for key rotation and removal
   - Ensure compatibility with Afterburn's existing SSH key handling

3. **Hostname Configuration**  
   - Implement setting of instance hostname based on Azure metadata
   - Integrate with Afterburn's hostname handling mechanisms
   - Support custom hostname configurations

4. **Network Configuration**  
   - Support Azure's network configuration (DHCP, static IPs, DNS settings)
   - Implement compatibility with Afterburn's network setup strategies
   - Add support for advanced networking features (VNet integration, network security groups)

5. **User Data Execution**  
   - Allow execution of custom user data scripts
   - Support cloud-init formats if needed
   - Ensure execution environment aligns with Afterburn's security policies

6. **Init System Integration**  
   - Implement running as a systemd service for proper boot-time execution
   - Align with Afterburn's existing systemd targets and dependencies
   - Add support for other init systems for broader compatibility

7. **Configurable Options**  
   - Provide configurable parameters (e.g., logging verbosity)
   - Implement management through cloud-init-style settings or Afterburn extensions
   - Ensure flexibility for various use cases

8. **Error Handling and Logging**  
   - Implement robust error handling with clear failure messages
   - Align with Afterburn's logging framework
   - Implement different log levels for debugging and production use

9. **Testing and Validation**  
    - Develop comprehensive unit tests for Azure-Init integration
    - Implement integration tests with Afterburn
    - Create end-to-end tests for Azure environments
    - Establish continuous integration pipeline

10. **Documentation and Examples**  
    - Create detailed documentation for Azure-Init integration
    - Provide usage examples and best practices
    - Develop troubleshooting guides
