Docker Package Registry not working with sub directory?

[Rincewind34]

Description

According to this documentation: https://docs.gitea.io/en-us/packages/container/ I think it is not possible to use the package registry with docker, if GitEa is running in a sib directory as in "example.com/gitea".

Is this something that one can bypass by altering the docker push command?

Use a reverse proxy (nginx for example) to rewrite the URL by removing the static part before passing it to your Gitea instance.

That's not a Gitea limitation. The docker api needs the /v2/ endpoint.

Thanks for the feedback! I'll be trying the proxy tomorrow with a colleague. But I did a little digging and it seems to me that this can (and should?) be configured on the server side using the prefix setting: https://docs.docker.com/registry/configuration/#http

The registry supports that but the/every client does not. See #18438 (comment) and the following posts for more informations.

Thanks guys! I'm no expert but I managed to get this working. Running gitea and nginx with docker compose -- add this to nginx:

    location /gitea/ { ## normal GitEA configuration
        client_max_body_size 10G;
        proxy_pass http://gitea:3000/;
    }

    location /v2/ { ## NEW, necessary for docker registry.
        client_max_body_size 10G;
        proxy_pass http://gitea:3000/v2/;
    }

    }

This should be added to the gitea documentation for nginx for subfolders
