You can configure the Docker client to use [GitHub Packages to publish and retrieve docker images](https://docs.github.com/en/packages/using-github-packages-with-your-projects-ecosystem/configuring-docker-for-use-with-github-packages).
To authenticate against the [GitHub Container Registry](https://docs.github.com/en/packages/getting-started-with-github-container-registry),
you will need to create a new [personal access token (PAT)](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token)
with the [appropriate scopes](https://docs.github.com/en/packages/getting-started-with-github-container-registry/migrating-to-github-container-registry-for-docker-images#authenticating-with-the-container-registry).
[Create a service principal](https://docs.microsoft.com/en-us/azure/container-registry/container-registry-auth-service-principal#create-a-service-principal)
with access to your container registry through the [Azure CLI](https://docs.microsoft.com/en-us/cli/azure/install-azure-cli)
and take note of the generated service principal's ID (also called _client ID_) and password (also called _client secret_).
Use a service account with the ability to push to GCR and [configure access control](https://cloud.google.com/container-registry/docs/access-control).
Then create and download the JSON key for this service account and save content of `.json` file
[as a secret](https://docs.github.com/en/actions/configuring-and-managing-workflows/creating-and-storing-encrypted-secrets#creating-encrypted-secrets-for-a-repository)
called `GCR_JSON_KEY` in your GitHub repo. Ensure you set the username to `_json_key`.
Use a service account with the ability to push to GAR and [configure access control](https://cloud.google.com/artifact-registry/docs/access-control).
Then create and download the JSON key for this service account and save content of `.json` file
[as a secret](https://docs.github.com/en/actions/configuring-and-managing-workflows/creating-and-storing-encrypted-secrets#creating-encrypted-secrets-for-a-repository)
called `GAR_JSON_KEY` in your GitHub repo. Ensure you set the username to `_json_key`.

Use an IAM user with the [ability to push to ECR](https://docs.aws.amazon.com/AmazonECR/latest/userguide/ecr_managed_policies.html).
Then create and download access keys and save `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` [as secrets](https://docs.github.com/en/actions/configuring-and-managing-workflows/creating-and-storing-encrypted-secrets#creating-encrypted-secrets-for-a-repository)

in your GitHub repo.

password: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
env:

```
> Replace `<region>` with its respective value (default `us-east-1`).
You can also use the [Configure AWS Credentials](https://github.com/aws-actions/configure-aws-credentials) action in
To push into OCIR in specific tenancy the [username](https://www.oracle.com/webfolder/technetwork/tutorials/obe/oci/registry/index.html#LogintoOracleCloudInfrastructureRegistryfromtheDockerCLI)
must be placed in format `<tenancy>/<username>` (in case of federated tenancy use the format `<tenancy-namespace>/oracleidentitycloudservice/<username>`).
For password [create an auth token](https://www.oracle.com/webfolder/technetwork/tutorials/obe/oci/registry/index.html#GetanAuthToken). Save username and token
[as a secrets](https://docs.github.com/en/actions/configuring-and-managing-workflows/creating-and-storing-encrypted-secrets#creating-encrypted-secrets-for-a-repository) in your GitHub repo.

Since [Dependabot](https://docs.github.com/en/github/administering-a-repository/keeping-your-actions-up-to-date-with-github-dependabot)
has [native GitHub Actions support](https://docs.github.com/en/github/administering-a-repository/configuration-options-for-dependency-updates#package-ecosystem),
to enable it on your GitHub repo all you need to do is add the `.github/dependabot.yml` file:
This action is only available for Linux [virtual environments](https://help.github.com/en/articles/virtual-environments-for-github-actions#supported-virtual-environments-and-hardware-resources).
