[Grafana] Reverse proxy not working with Caddy2 but Caddy1 #3377

Closed mrplug closed 4 years ago

mrplug commented 4 years ago

Hey!

I observed some very strange behavior: Reverse proxy with Grafana is working like a charm, when using Caddy1. Both servers are running a docker container.

As soon as i switch to Caddy2 i only see a blank page.

Caddyfile1 grafana.domain.net { proxy / http://grafana:3000 }

Caddyfile2 grafana.domain.net { reverse_proxy / http://grafana:3000 }

I already checked the migration documentation and i can't see any specific why this should not work. Anybody with a similar behavior when migrating from v1 to v2?

Try:

 grafana.domain.net { reverse_proxy http://grafana:3000 }

With your caddyfile2, what's happening is requests to only / are matched and the other subpaths are getting ignored since they are not being handled. By default, reverse_proxy without a matcher works for all requests.

Yep, and our upgrade guide explains this: https://caddyserver.com/docs/v2-upgrade#primary-changes

Thanks for the answer @kayg04 !
