Redis – docker push to local registry fails

Registry container is running at port 5000.

I have tried all the possible options mentioned in similar issues such as

  1. net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)
  2. https://github.com/ubuntu/microk8s/issues/196

but nothing seems to help resolve the issue. Any suggestions on how to approach a solution?

    I had this same issue.

    I changed the tag name to be 127.0.0.1:5000 instead of localhost and it completed as expected when pushing.

    In my case, local registry was connected to the kind cluster.
    docker push worked after I disconnected registry from the network:
    docker network disconnect "kind" "kind-registry"
