Connecting a repository to a container image

When you link a container image with a repository, the package landing page will show information and links from the repository, such as the README.

To connect a repository and a container image on GitHub, they must share the same owner on GitHub. For example, both my_repo and hello_docker are owned by the user monalisa:

https://github.com/monalisa/my_repo
https://github.com/monalisa/hello_docker

Connecting a repository to a user-owned container image on GitHub

1. On GitHub, navigate to the main page of your user account.

2. In the top right corner of GitHub, click your profile photo, then click Your profile.

   

3. On your profile page, in the top right, click Packages.

   

4. Search for and select your package.

5. In the top right of your container image's landing page, click Package settings.

   

6. Under your package versions, click Connect repository.

   

7. Select a repository, then click Connect repository.

   

Connecting a repository to an organization-owned container image on GitHub

1. On GitHub, navigate to the main page of your organization.

2. Under your organization name, click Packages.

   

3. Search for and select your package.

4. In the top right of your container image's landing page, click Package settings.

   

5. Under your package versions, click Connect repository.

   

6. Select a repository, then click Connect repository.

   

Connecting a repository to a container image on the command line

1. In your Dockerfile, add this line, replacing OWNER and REPO with your details:

   LABEL org.opencontainers.image.source=https://github.com/OWNER/REPO

   For example, if you're the user monalisa and own my-repo, you would add this line to your Dockerfile:

   LABEL org.opencontainers.image.source=https://github.com/monalisa/my-repo

   For more information, see "LABEL" in the official Docker documentation and "Pre-defined Annotation Keys" in the opencontainers/image-spec repository.

2. Build your container image. This example builds an image from the Dockerfile in the current directory and assigns the image name hello_docker.

   $ docker build -t hello_docker .

3. Optionally, review details for the Docker image you want to tag.

   $ docker images
   > REPOSITORY                                            TAG                 IMAGE ID            CREATED             SIZE
   > ghcr.io/my-org/hello_docker         latest              38f737a91f39        47 hours ago        91.7MB
   > ghcr.io/my-username/hello_docker    latest              38f737a91f39        47 hours ago        91.7MB
   > hello-world                                           latest              fce289e99eb9        16 months ago       1.84kB

4. Tag your Docker image with your desired image name and hosting destination.

   $ docker tag IMAGE_NAME ghcr.io/OWNER/NEW_IMAGE_NAME:TAG

   For example:

   $ docker tag 38f737a91f39 ghcr.io/monalisa/hello_docker:latest

5. If you haven't already, authenticate to GitHub Container Registry. For more information, see "Authenticating to GitHub Container Registry."

   $ echo $CR_PAT | docker login ghcr.io -u USERNAME --password-stdin
   > Login Succeeded

6. Push your container image to GitHub Container Registry.

   $ docker push ghcr.io/OWNER/IMAGE-NAME:TAG

   For example:

   $ docker push ghcr.io/monalisa/hello_docker:latest
