Note: GitHub Container Registry is currently in public beta and subject to change. During the beta, storage and bandwidth are free. To use GitHub Container Registry, you must enable the feature preview. For more information, see "About GitHub Container Registry" and "Enabling improved container support."
To push and pull container images owned by an organization, an organization admin must enable GitHub Container Registry for the organization. For more information, see "Enabling improved container support."
If you want to authenticate to GitHub Container Registry in a GitHub Actions workflow, then you must use a personal access token (PAT). The
GITHUB_TOKEN does not currently have the required permissions. During the GitHub Container Registry beta, the only supported form of authentication is the PAT.
PATs can grant broad access to your account. We recommend selecting only the necessary read, write, or delete
package scope when creating a PAT to authenticate to the container registry. Avoid including the
repo scope in a PAT used by a GitHub Actions workflow because it gives unnecessary additional access.
If you'd like to use the container registry in actions during the beta, follow our security best practices for PAT use 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: If you select the
write:packagesscope, deselect the
reposcope when creating the PAT. Adding a PAT with the
reposcope as a secret in your repository allows the credential to be accessible to all collaborators in the repository. This gives unnecessary additional access when a PAT with the
reposcope is used within an action. For more information on security best practices for actions, see "Security hardening for GitHub Actions."
- 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 GitHub 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 access control and visibility for container images."
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
