How to push a docker image to a private repository

Question

I have created a custom image that i wish to upload onto my private repository on DockerHub. I tagged it as "project/custom-image-1" . Whenever i try to push this particular custom image onto my private registry , it gets pushed to the public repository and not the private one.

Can anyone help me out with this? what is the standard way to do this?

Answer 1

So there is a standard way to do this, you can first tag your image with the URI of your private repository, follow the below syntax :

docker tag [OPTIONS] IMAGE[:TAG] [REGISTRYHOST/][USERNAME/]NAME[:TAG]

Then once you are done tagging the image you want to push, just use the docker push command, like how it's given below : 

docker push NAME[:TAG]

If the above doesn't work out, try logging into dockerhub account first

docker login --username username

Then tag your image with the correct repository

docker tag my-image username/my-repo

And then finally push it 

docker push username/my-repo
