docker unauthorized: authentication required - upon push with successful login

Question

While pushing the docker image (after successful login) from my host I am getting \"unauthorized: authentication required\".

Details below.

-bash-4.         


        

Answer 1

I was running into a similar issue with a similarly unhelpful error message, but it turned out to be because I was trying to push an image that I had built against a docker-machine managed instance.

When I logged into the instance itself, did docker login and docker push everything worked fine.
