如何将图像推送到 Docker 集线器

Question

I can't push my local image to Docker hub. I checked every topics in here but still couldn't solve it.

My local image is like below;

[root@DOCKER2Demo]# docker images
REPOSITORY                  TAG                 IMAGE ID            CREATED             SIZE
companyrepo123/man-demo        latest                b86sbfd26        41 minutes ago      5.31GB

So I want to push this image to the "companyrepo123/man-demo:latest" repository.

So I login successfully with "docker login" and run the command below

docker push companyrepo123/man-demo:latest

But gives the error below;

The push refers to repository [docker.io/companyrepo123/man-demo]

I already login. Tried to logout and login and but still same.

Please noticed that my username is not "companyrepo123". This is our company's repository, my username to login Docker hub is "yatta".

How can I push that image?

Regards.

Answer 1

You need to push to a repository under your namespace in Docker Hub, where the first part of that path is your username or organization. So myrepo123 would be your username.

Next, you'll want to create the repository, myrepo123/man-demo on Docker Hub (from the web interface), and if this is under an organization, make sure your user has access to push to that repo within the organization.

If you've done that, then make sure you have logged into Docker Hub, with the correct username, using:

docker login

If you have enabled 2fa on Hub, the password for this is an access token you generate from the web page.
