How to push a docker image to a private repository

You need to tag your image correctly first with your registryhost:

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

Then docker push using that same tag.

docker push NAME[:TAG]

Example:

docker tag 518a41981a6a myRegistry.com/myImage
docker push myRegistry.com/myImage

Just three simple steps:

1. docker login --username username

   • prompts for password if you omit --password which is recommended as it doesn't store it in your command history

2. docker tag my-image username/my-repo

3. docker push username/my-repo
