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

If you running windows 7 docker Registry

1. Start **Docker Quick Start terminal** run (this terminal enables connection ) Until you pushed images , that will keep token alive .
2. Login docker login

3. Make sure you tag the image with username

   docker build -f Dockerfile -t 'username'/imagename

4. push image

   docker image push username/imagename

Note: image name all lowercase

Answer 2

I had the same problem but i fixed it with push with specified url. as: docker login -u https://index.docker.io/v1/

console output:

The push refers to a repository [docker.io/<username>/richcity]

Answer 3

Here the solution for my case ( private repos, free account plan)

https://success.docker.com/Datacenter/Solve/Getting_%22unauthorized%3A_authentication_required%22_when_trying_to_push_image_to_DTR

The image build name to push has to have the same name of the repos.

Example: repos on docker hub is: accountName/resposName image build name "accountName/resposName" -> docker build -t accountName/resposName

then type docker push accountName/resposName:latest

That's all.

Answer 4

Make sure your docker repositry name matches your local docker repo name. e.g lets say if you local repo name "kavashgar/nodjsapp"

then your should also have a repo names "kavashgar" in docker hub

Answer 5

in your configuration file ~/.docker/config.json add

{
        "auths": {
             "https://index.docker.io/v1/": {
                        "auth": "XXXXXXXXXXXXX",
                        "email": "my_email@gmail.com"
                }
        }
}

where XXXXX is base64 encoding of your username:password (the : is included) of https://hub.docker.com

in my case i had the same error with a pull. the problem (under windows) was provoked by double docker running process, so a kill them all and restart one service and it works .

Answer 6

There has already been good answers but I would like to mention one - You do NOT need to create a repository in advance before pushing it.

The problem for me was that I didn't set the correct username of the account I logged in to. But once the correct username is set before the image (e.g. YOURNAME/YOURIMAGE) via its tag, you can push it without creating a new repository in advance.

sudo docker tag IMAGE:VERSION USERNAME/IMAGE:VERSION
sudo docker push USERNAME/IMAGE:VERSION
