We attempted to package this but failed. (First packaging attempt)

If somebody else wants to try, this is what we learned:

# Lessons from Attempting to Package Pelican Panel for Cloudron


## Key Lessons Learned
Here are the top 5 things that caused the most trouble:

- **Health Check Stalls**: Pelican's slow startup (e.g., DB migrations, asset compilation) often times out Cloudron's health checks. Extend the Dockerfile's `HEALTHCHECK --start-period` to 120s+ for real use, or use a temporary dummy (e.g., `CMD true`) to bypass for debugging—revert it later to avoid false "healthy" states.
- **Env Var Management**: Cloudron rejects an "environment" array in the manifest (validation error: "Unknown property"). Hardcode defaults in Dockerfile `ENV` lines, then manually edit `/app/data/.env` via SSH post-install to inject Cloudron placeholders like `${MYSQL_HOST}` (get them from `cloudron inspect --app <fqdn>`).
- **Manifest Validation Issues**: Cloudron is strict—unsupported fields fail installs outright. Stick to the official schema (check [Cloudron docs](https://cloudron.io/documentation/custom-apps/manifest/)), test with JSON validators, and remove extras like custom env sections.
- **Git Merge Conflicts**: Editing files locally vs. directly on GitHub leads to push rejections. Always run `git pull origin main` before changes, and resolve conflicts by manually editing/removing markers (e.g., `<<<<<<< HEAD`, `=======`, `>>>>>>>`).
- **Image Registry Choices**: GHCR (GitHub Container Registry) can have pull/auth issues in Cloudron; Docker Hub is more reliable for public images. Ensure the manifest's "dockerImage" matches your pushed tag, and verify pulls locally before installing.

# Storage symlinks for Cloudron persistence (add in RUN)

Post-Install SSH Commands for Fixes

# SSH to server, then:
cloudron logs --app your-app-fqdn  # Check high-level logs
docker ps | grep pelican  # Get container ID
docker logs <container-id>  # Detailed app logs
docker exec -it <container-id> /bin/sh  # Enter container
# Inside: apk add nano; nano /app/data/.env  # Edit env vars
# Then: php artisan migrate --force; supervisorctl restart all
# Exit and: cloudron restart --app your-app-fqdn

Final Notes

• Testing Tip: Run the image locally (docker run -p 80:80 yourimage) before Cloudron to verify health checks and env vars.
• Why It's Tricky: Pelican (Laravel-based) needs precise env setup and can be slow to boot—manual SSH tweaks were essential.
• Sharing: If you build on this, post updates here or on Pelican's GitHub.
