Cockpit and Traefik

HTTP 500, HTTP 404…etc

Cockpit’s web server automatically redirects to port 443 with a self-defined SSL certificate.

For my use case, I wanted SSL to terminate at Traefik, so I set the backend to point to http and disabled Cockpit’s SSL redirect.

Note: To proxy to my host that’s running traefik and docker, I need to use the docker network’s local IP (172.18.0.1), not the server’s LAN IP (192.168.xxx.xxx).

```rules.toml
[backends.backend-host-cockpit-http]
[backends.backend-host-cockpit-http.servers]
[backends.backend-host-cockpit-http.servers.server-1]
url = "http://172.18.0.1:9090"
```
```cockpit.conf
[WebService]
Origins = https://host-cockpit.mydomain.com wss://host-cockpit.mydomain.com
ProtocolHeader = X-Forwarded-Proto
AllowUnencrypted=true
```
