drjmf Mycelia AI Stack Update Guide
This skill ensures that Mycelia AI services are updated safely without losing data or configurations.
Core Principles
- Persistence First: NEVER use 'docker compose down --volumes'. Always preserve volumes.
- Secret Synchronization: Always source credentials from /opt/mycelia-ai-stack/.secrets.
- Service Isolation: Update one service at a time.
- Major Version Safety: For major version jumps (e.g., Postgres 16 -> 18), check for directory structure changes.
Workflow
1. Identify Target
- Determine the service and desired version.
- Verify the management script in /opt/mycelia-ai-stack/scripts/.
2. Update Management Script
- Use sed to update the image tag in the corresponding script.
3. Execute Update
- Run the management script with the 'create' command.
- This command stops the old container and replaces it while preserving volumes.
4. Verification
- Confirm the new version: 'docker inspect --format {{.Config.Image}}'
- Check logs: 'docker logs --tail 50'
