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

Same problem here, during pushing image:

unauthorized: authentication required

What I did:

docker login --username=yourhubusername --email=youremail@company.com

Which it printed:

--email is deprecated (but login succeeded still)

Solution: use the latest login syntax.

docker login

It will ask for both username and password interactively. Then the image push just works.

Even after using the new syntax, my ~/.docker/config.json looks like this after logged in:

{
    "auths": {
        "https://index.docker.io/v1/": {}
    },
    "credsStore": "osxkeychain"
}

So the credential is in macOS' keychain.
