How to solve requested access to the resource is denied error when pushing docker images to registry?

Problem

When you want to push an docker image to harbor or other docker registries, you would get this error:

[root@k8s-test-113 ~]# docker push 10.1.2.112:8443/envoyproxy/envoy-alpine:latest
The push refers to repository [10.1.2.112:8443/envoyproxy/envoy-alpine]

denied: requested access to the resource is denied

Solution

You should specify the repository name in the tag of the docker image, e.g.

Instead of this tag:

10.1.2.112:8443/envoyproxy/envoy-alpine:latest

You should use this tag:

10.1.2.112:8443/gcr.io/envoyproxy/envoy-alpine:latest

Because there is a repository in the your registry like this:

Other operations

You should make sure that you have logged in the harbor repo:

docker logout
docker login -u admin 10.1.2.112:8443
