Configuration Example

Minimal Configuration

http:
  middlewares:
    pages-server:
      plugin:
        pages-server:
          pagesDomain: pages.example.com
          forgejoHost: https://git.example.com

Full Configuration

http:
  middlewares:
    pages-server:
      plugin:
        pages-server:
          # Required
          pagesDomain: pages.example.com
          forgejoHost: https://git.example.com
          # Optional
          forgejoToken: your-token
          errorPagesRepo: system/error-pages
          redisHost: localhost
          redisPort: 6379
          redisPassword: ""
          cacheTTL: 300

Note: SSL certificates are managed by Traefik's certificatesResolvers configuration, not by the plugin.

Known Limitations

1. Yaegi Compatibility: Redis client falls back to in-memory cache due to Yaegi limitations
2. Certificate Management: SSL certificates are managed exclusively by Traefik's certificatesResolvers configuration
3. Single Pages Domain: Currently supports one pages domain per plugin instance
4. File Extension Heuristic: Profile vs repository detection uses file extension presence

Future Enhancements

Potential improvements for future versions:

1. Multi-domain Support: Support multiple pages domains in one instance
2. Branch Selection: Allow specifying which branch to serve
3. Build Integration: Support for static site generators
4. Webhook Support: Automatic cache invalidation on git push
5. Analytics: Built-in access logging and analytics
6. Rate Limiting: Per-repository or per-user rate limits
7. Access Control: Fine-grained access control for private sites
