Docker login succeeds but not showing any images from the repository

Question

We have an on prem version of artifactory installed which can host a docker repository. I can browse the repository from chrome and there are some images hosted.

When i do docker login [dns of my reverse proxy], i get the prompt to supply my credentials which i do. and then i get the message 'Login Succeeded'

I then do a docker push [image name]:latest and this is output i get:

The push refers to repository [docker.io/library/[image name]]
4642eff80520: Preparing
[...truncated output...]
bcf2f368fe23: Waiting
denied: requested access to the resource is denied

Here it looks like it's going to some completely different repository to the one i logged in to? :

docker.io/library/[image name]

then when i do docker logout, i get the output

Not logged in to https://index.docker.io/v1/

I don't understand why it is not letting me push my image to the repository i logged in to?, is it because that's not the repository and it is just the reverse proxy server?

I am using Docker for Windows, output of docker version

Answer 1

If you're running a custom registry to host your images you need to tell docker how to do this.

The documentation for docker push has an example as well as the documentation on how to run your own registry. You need to prefix the host to your image. The example given in the docker push documentation is as follows:

$ docker push registry-host:5000/myadmin/rhel-httpd

Depending on what version of docker you're running you might be able to change the default registry. At least according to this question on StackOverflow. Beware that this seem to have been discussed before and won't be a standard feature.
