Unusable application

@lanhild I just tried to reproduce this and it seems to work fine. Have you added the local registry app as a Private docker registry i.e under System -> Docker -> Registries? The local registry app is not automatically available for app install (same cloudron or different cloudron).

It may be the https issue which local to local can't connect

joseph

I assumed .local was like .example. Did you literally mean .local ?

Lanhild

@joseph I used .local for the sake of my example

That's what I'm attempting to do, but it results in the error I mentioned.

joseph

In the registry configuration in Cloudron settings, the error Invalid serverAddress: socket hang up appears whenever I attempt to save the private registry settings.

OK, I missed this one. Can you try docker login on the server itself and see if that works ?

Lanhild

@joseph it doesn't, gives me a timeout error. I'll add relevant logs in a few minutes.

Lanhild

@joseph

Error response from daemon: Get "https://registry.cloudron.local/v2/": context deadline exceeded

@lanhild We have to debug this step by step.

Does host registry.cloudron.local resolve to public IP?
Check if nginx can reach the container.. docker ps | grep com.docker.registry to get container ID. docker inspect bea487bec441 | grep IPAddress to get local IP. curl http://172.18.20.34:5000/asdf -v should get some response for the registry. It will have Docker-Distribution-Api-Version header.
Then curl https://registry.cloudron.local ? This should give some UI page or login page of the registry

Depending on where it fails, we have to proceed. FWIW, docker login to same cloudron registry works fine on my servers.

@joseph My answers, step-by-step as you formatted it in your message:

Yes.
Reachable, Docker-Distribution-Api-Version: registry/2.0

docker login from the Cloudron server results in the following

Error response from daemon: Get "https:/registry.cloudron.local/v2/": net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

docker login from any other remote works perfectly fine.

I can't repro the issue on the demo server.

Cloudron makes it easy to run web apps like WordPress, Nextcloud, GitLab on your server. Find out more or install now.
