The Container registry currently supports the following container image formats:
When installing or publishing a Docker image, the Container registry supports foreign layers, such as Windows images.
To authenticate to the Container registry within a GitHub Actions workflow, use the
GITHUB_TOKEN for the best security and experience. If your workflow is using a personal access token (PAT) to authenticate to
ghcr.io, then we highly recommend you update your workflow to use the
For guidance on updating your workflows that authenticate to
ghcr.io with a personal access token, see "Upgrading a workflow that accesses
For more information about the
GITHUB_TOKEN, see "Authentication in a workflow."
If you're using the Container registry in actions, follow our security best practices at "Security hardening for GitHub Actions."
Create a new personal access token (PAT) with the appropriate scopes for the tasks you want to accomplish. If your organization requires SSO, you must enable SSO for your new token.
Note: By default, when you select the
write:packagesscope for your personal access token (PAT) in the user interface, the
reposcope will also be selected. The
reposcope offers unnecessary and broad access, which we recommend you avoid using for GitHub Actions workflows in particular. For more information, see "Security hardening for GitHub Actions." As a workaround, you can select just the
write:packagesscope for your PAT in the user interface with this url:
- Select the
read:packagesscope to download container images and read their metadata.
- Select the
write:packagesscope to download and upload container images and read and write their metadata.
- Select the
delete:packagesscope to delete container images.
For more information, see "Creating a personal access token for the command line."
- Select the
Save your PAT. We recommend saving your PAT as an environment variable.
$ export CR_PAT=YOUR_TOKEN
Using the CLI for your container type, sign in to the Container registry service at
$ echo $CR_PAT | docker login ghcr.io -u USERNAME --password-stdin > Login Succeeded
This example pushes the latest version of
$ docker push ghcr.io/OWNER/IMAGE_NAME:latest
This example pushes the
2.5 version of the image.
$ docker push ghcr.io/OWNER/IMAGE-NAME:2.5
When you first publish a package, the default visibility is private. To change the visibility or set access permissions, see "Configuring a package's access control and visibility."
To ensure you're always using the same image, you can specify the exact container image version you want to pull by the
digest SHA value.
To find the digest SHA value, use
docker pulland copy the SHA value after
$ docker inspect ghcr.io/OWNER/IMAGE_NAME
Remove image locally as needed.
$ docker rmi ghcr.io/OWNER/IMAGE_NAME:latest
Pull the container image with
@YOUR_SHA_VALUEafter the image name.
$ docker pull ghcr.io/OWNER/IMAGE_NAME@sha256:82jf9a84u29hiasldj289498uhois8498hjs29hkuhs
$ docker pull ghcr.io/OWNER/IMAGE_NAME
Docker CLI example showing an image pulled by its name and the
1.14.1 version tag:
$ docker pull ghcr.io/OWNER/IMAGE_NAME:1.14.1 > 5e35bd43cf78: Pull complete > 0c48c2209aab: Pull complete > fd45dd1aad5a: Pull complete > db6eb50c2d36: Pull complete > Digest: sha256:ae3b135f133155b3824d8b1f62959ff8a72e9cf9e884d88db7895d8544010d8e > Status: Downloaded newer image for ghcr.io/orgname/image-name/release:1.14.1 > ghcr.io/orgname/image-name/release:1.14.1
$ docker pull ghcr.io/OWNER/IMAGE_NAME:latest > latest: Pulling from user/image-name > Digest: sha256:b3d3e366b55f9a54599220198b3db5da8f53592acbbb7dc7e4e9878762fc5344 > Status: Downloaded newer image for ghcr.io/user/image-name:latest > ghcr.io/user/image-name:latest
This example builds the
$ docker build -t hello_docker .
Find the ID 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
Tag your Docker image using the image ID and your desired image name and hosting destination.
$ docker tag 38f737a91f39 ghcr.io/OWNER/NEW_IMAGE_NAME:latest
