eda maintenance

The eda maintenance command group activates and deactivates instant maintenance mode for your applications (alias: eda mm). When enabled, Caddy immediately serves an elegant, responsive HTTP 503 Maintenance page across all custom domains and public tunnels without stopping your containers or dropping connections.

4. Custom 503 Templates & System ArchitectureCopy Anchor Link

• Zero Container Interruption: Your application container and managed databases remain untouched and fully accessible via eda sh and eda exec. You can safely perform database schema migrations while visitors see the maintenance page.
• Custom Branding: Drop a custom HTML file into the server's custom/files directory:
  • Global fallback: /opt/explita/deploy/custom/files/503.html
  • Per-app page: /opt/explita/deploy/custom/files/<appId>.503.html
• Built-In Fallback: If no custom file is found on disk, Explita's responsive built-in dark cyber 503 template is served automatically.
• SEO Safe: Search engine bots receive proper HTTP 503 Service Unavailable with Retry-After headers, preserving domain indexing.
