To authenticate against the [GitHub Container Registry](https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-container-registry),
You may need to [manage write and read access of GitHub Actions](https://docs.github.com/en/packages/managing-github-packages-using-github-actions-workflows/publishing-and-installing-a-package-with-github-actions#upgrading-a-workflow-that-accesses-ghcrio)
You can also use a [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_).
You can use either workload identity federation based keyless authentication or service account based authentication.
#### Workload identity federation based authentication
Configure the workload identity federation for github actions in gcloud (for steps, [refer here](https://github.com/google-github-actions/auth#setting-up-workload-identity-federation)). In the steps, your service account should the ability to push to GCR. Then use google-github-actions/auth action for authentication using workload identity like below:
> Replace `<workload_identity_provider>` with configured workload identity provider. For steps to configure, [refer here](https://github.com/google-github-actions/auth#setting-up-workload-identity-federation).
> Replace `<service_account>` with configured service account in workload identity provider which has access to push to GCR
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)

#### Workload identity federation based authentication
Configure the workload identity federation for github actions in gcloud (for steps, [refer here](https://github.com/google-github-actions/auth#setting-up-workload-identity-federation)). In the steps, your service account should the ability to push to GAR. Then use google-github-actions/auth action for authentication using workload identity like below:
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)
Use an IAM user with the ability to [push to ECR with `AmazonEC2ContainerRegistryPowerUser` managed policy for example](https://docs.aws.amazon.com/AmazonECR/latest/userguide/ecr_managed_policies.html#AmazonEC2ContainerRegistryPowerUser).
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)
Use an IAM user with the ability to [push to ECR Public with `AmazonElasticContainerRegistryPublicPowerUser` managed policy for example](https://docs.aws.amazon.com/AmazonECR/latest/public/public-ecr-managed-policies.html#AmazonElasticContainerRegistryPublicPowerUser).
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)
To push into OCIR in specific tenancy the [username](https://www.oracle.com/webfolder/technetwork/tutorials/obe/oci/registry/index.html#LogintoOracleCloudInfrastructureRegistryfromtheDockerCLI)
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)
> Replace `<region>` with their respective values from [availability regions](https://docs.cloud.oracle.com/iaas/Content/Registry/Concepts/registryprerequisites.htm#Availab)
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:
