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.

Answer 2

I tried all the methods I can find online and failed. Then I read this post and get some ideas from @Alex answer. Then I search about ""credsStore": "osxkeychain"" which is used in my config.json. The I follow this link https://docs.docker.com/engine/reference/commandline/login/ to logout and then login again. Finally, I can push my image successfully.

Answer 3

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.

Answer 4

Even I logged in and checked all the configuration, it still does not work !!!

It turned out that when I build my docker, I forget to put my username before the repo name

docker build docker-meteor-build 

(build successfully)

And then when I pushed to my repository, I used

docker push myname/docker-meteor-build 

It will show the unauthorized authentication required

So, solution is then name of build and the push should be exactly the same

docker build myname/docker-meteor-build 
docker push myname/docker-meteor-build 

Answer 5

What worked for me was to create a new repository and rename the image with

$ docker tag image_id myname/server:latest

Answer 6

I had a similar problem.

Error response from daemon: Get https://registry-1.docker.io/v2/hadolint/hadolint/manifests/latest: unauthorized: incorrect username or password

I found out out that even if I login successfully with the docker login command, any pull failed. I tried to clean up the ~/.docker/config.json but nothing improved.

Looking in the config file I've seen that the credentials were not saved there but in a "credsStore": "secretservice". In Linux this happen to be the seahorse or Passwords and Keys tool. I checked there and I cleanup all the docker hub login. After this a new docker login worked as expected.
