Using GitHub Container Registry to store images 

Prerequisite:

1. A GitHub account with your GitHub username
2. A personal access token

Step 1: Create new Personal API Token

The username to the registry is the same as your GitHub username. For the password you need to create a GitHub personal token.

When creating the personal token, you need to select at least the following scopes:

write:packages
read:packages
delete:packages
repo if your repository is private; if public, do not select
Once you create the token, note it down.

Step 2: Login to ghcr.io

docker login ghcr.io --username github-account
[Paste your GitHub token on this prompt]

Step 3: Tag your image

docker tag image-id ghcr.io/github-account/image-name:image-version

Example

docker tag 15a4d12e9b2f ghcr.io/my-username/repo-example:1.0

You can find your image ID by command

docker images

Step 4: Push image to ghcr.io

docker push ghcr.io/my-username/repo-example:1.0

Then you can link to your code repository if you want in UI or by command

LABEL net.anhtuan.image.source https://github.com/USERNAME/REPOSITORY
