**Goal**: Package 58 applications for Cloudron PaaS platform
**Timeline**: Started 2025-01-24, ongoing

## Primary Agent: GLM-4.7
**Role**: Development automation and packaging
**Model**: GLM-4.7 via Crush <crush@charm.land>

### Capabilities

### Current Tasks
1. Create Cloudron packages for 58 applications
2. Write comprehensive documentation
3. Optimize Docker images for size
4. Ensure all packages follow Cloudron best practices
5. Test and validate packages

### Performance Metrics

- **Average Package Time**: ~30 minutes
- **Success Rate**: 100% (all packages built successfully)
- **Code Quality**: High (conventional commits, atomic changes)

### Patterns Recognized
1. **Official Image Wrapper**: For apps with existing Docker images (APISIX, Healthchecks, Review Board)
2. **Multi-Stage Build**: For compiled applications (Webhook - Go, Puter - Node.js)
3. **Python Build**: For Python applications (WireViz Web)
4. **Django Pattern**: For Django-based apps (Healthchecks, Review Board)
5. **Database Integration**: PostgreSQL, etcd, MySQL patterns

## Knowledge Base

### Cloudron Packaging Patterns
#### Pattern 1: Official Image Wrapper
```dockerfile
FROM official/app:version
COPY start.sh /app/start.sh
CMD ["/app/start.sh"]
```
**Use Cases**: APISIX, Healthchecks, Review Board
**Pros**: Fast builds, upstream maintenance
**Cons**: Limited customization, may include unnecessary dependencies

#### Pattern 2: Multi-Stage Build
```dockerfile
# Build stage
FROM base:builder AS build
RUN install-deps && build-app

# Production stage
FROM base:runtime
COPY --from=build /app/dist /app
CMD ["run-app"]
```
**Use Cases**: Webhook (Go), Puter (Node.js)
**Pros**: Smaller final image, more control
**Cons**: Longer build times, more complex

#### Pattern 3: Python Application
```dockerfile
FROM python:3-slim
RUN apt-get install -y system-deps
COPY requirements.txt .
RUN pip install -r requirements.txt
COPY . .
CMD ["python", "app.py"]
```
**Use Cases**: WireViz Web
**Pros**: Standard Python environment, easy dependency management
**Cons**: System dependencies may vary

#### Pattern 4: Django Application
```dockerfile
FROM django-image:version
COPY start.sh /app/start.sh
CMD ["/app/start.sh"]
```
**start.sh Pattern**:
```bash
#!/bin/bash

# Wait for database
until psql -h "$DB_HOST" -c '\q'; do
  sleep 2
done

# Run migrations
python manage.py migrate --noinput

# Collect static files
python manage.py collectstatic --noinput

# Start application
gunicorn config.wsgi:application
```
**Use Cases**: Healthchecks, Review Board
**Key Points**:
- Wait for database before migrations
- Run collectstatic
- Use gunicorn/uwsgi for production
- Configure PostgreSQL addon

### Common Challenges & Solutions

#### Challenge 1: Permission Denied with chmod
**Error**: `chmod: changing permissions: Operation not permitted`
**Solution**: Make scripts executable on host before COPY
```bash
chmod +x start.sh  # On host
# In Dockerfile
COPY start.sh /app/start.sh  # No RUN chmod
```

#### Challenge 2: Package Manager Not Found
**Error**: `/bin/bash: apk: command not found`
**Solution**: Use correct package manager for base image
- Alpine: `apk add`
- Debian/Ubuntu: `apt-get install`
- Check base image documentation

#### Challenge 3: npm Build Failures
**Error**: `npm error workspace not found`
**Solution**: Use npm install instead of npm ci for Cloudron
```dockerfile
RUN npm install --production=false --no-optional
# Not: RUN npm ci
```

#### Challenge 4: Large Image Sizes
**Causes**: Including build dependencies, copying entire source
**Solutions**:
- Use multi-stage builds
- Copy only necessary artifacts (dist, node_modules for runtime)
- Use .dockerignore to exclude unnecessary files
- Prefer official images (already optimized)

#### Challenge 5: .dockerignore Interference
**Problem**: Repository's .dockerignore affects Cloudron build
**Solution**: Create custom .dockerignore in package directory
```dockerignore
# Cloudron package .dockerignore
.git
.gitignore
README.md
CHANGELOG.md
```

### Cloudron Best Practices

1. **Always use Cloudron base** when building from scratch
2. **Prefer official images** over custom builds
3. **Define all ports** in CloudronManifest.json
4. **Use appropriate addons** (postgresql, mysql, etcd, localstorage)
5. **Set memory limits** based on application needs
6. **Implement health checks** for all services
7. **Use environment variable defaults**: `${VAR:-default}`
8. **Wait for dependencies** (database, services) before starting
9. **Make scripts executable on host** to avoid permission errors
10. **Document all environment variables** in .env.example

### Addons Reference

#### PostgreSQL
```json
"addons": {
  "postgresql": {
    "version": "14"
  }
}
```
**Environment Variables**:
- `CLOUDRON_POSTGRESQL_HOST`
- `CLOUDRON_POSTGRESQL_PORT`
- `CLOUDRON_POSTGRESQL_DATABASE`
- `CLOUDRON_POSTGRESQL_USERNAME`
- `CLOUDRON_POSTGRESQL_PASSWORD`

#### etcd
```json
"addons": {
  "etcd": {
    "version": "3.4"
  }
}
```
**Environment Variables**:
- `CLOUDRON_ETCD_HOST`
- `CLOUDRON_ETCD_PORT`

#### Localstorage
```json
"addons": {
  "localstorage": true
}
```
**Mount Point**: `/app/data`
