Docker 注册表未在代理模式下拉取图像

Question

I cant get docker-registry to run in proxy mode. I've set up a registry with the following configuration:

version: 0.1
storage:
  filesystem:
    rootdirectory: /var/lib/registry
proxy:
  remoteUrl: https://index.docker.io/v1
http:
  addr: :5000
  host: https://[DOMAIN]

The registry is running in a kube cluster with an exposed service and ingress pointing the deployment.

In my gitlab runner I've set the registry-mirrors array in daemon.json config file to point to this server.

The docker-registry is clear and has no images pushed. However, when I try to run a gitlab job (using node:lts image) I get 404 error from the registry.

This means, my docker gilab runner is trying to pull from my registry proxy, however the proxy cache won't serve the request.

Does the proxy mode should run out of the box, or are there any other manual steps required?

Thanks in advance.

Attaching logs from my registry:

The setting is remoteurl not remoteUrl . The json fields are case sensitive.
