## Description

Backend for caddy/ui, a web interface for managing Caddy servers, Caddyfiles, routes, certificates, logs, and metrics. Requires the caddy-ui-frontend container and an existing Caddy server. Select the same user-defined Docker bridge network for both UI containers and Caddy. You can use an existing custom bridge network: change Network Type in both templates to that network. If you need a new network, run "docker network create caddy-ui" in the Unraid terminal before installing and select "Custom: caddy-ui". Keep the container names caddy-ui-backend and caddy-ui-frontend. Enable "admin 0.0.0.0:2019" in Caddy's global configuration block; keep the admin API private. Start the backend before the frontend. Set External UI URL to the exact address used in your browser, including scheme and port, such as http://192.168.1.10:9877. Open the frontend to create the administrator, save the

## Common questions

### Does caddy-ui-backend include the web interface in the same container?

No, the web frontend is a separate Docker image that is built with React and served via Nginx.

### Can I manage Caddy through the UI without editing config files?

Yes, the UI can manage proxy hosts, redirections, SSL certificates, and advanced routes without touching config files.

### Does a Caddy UI have to modify the Caddyfile directly?

No, Caddy can be configured via its API, and the Caddyfile produces the JSON config that Caddy actually runs.

### Why might Caddy fail to resolve internal services when used as a reverse proxy?

It can fail when the setup depends on the router's DNS host overrides to resolve internal service names to local IPs.
