You can make use of [environment variables](#environment-variables) to automatically
scale your pod replicas.
It's important to note that when a project is deployed to a Kubernetes cluster,
it relies on a Docker image that has been pushed to the
[GitLab Container Registry](../../user/project/container_registry.md). Kubernetes
fetches this image and uses it to run the application. If the project is public,
the image can be accessed by Kubernetes without any authentication, allowing us
to have deployments more usable. If the project is private/internal, the
Registry requires credentials to pull the image. Currently, this is addressed
by providing `CI_JOB_TOKEN` as the password that can be used, but this token will
no longer be valid as soon as the deployment job finishes. This means that
Kubernetes can run the application, but in case it should be restarted or
executed somewhere else, it cannot be accessed again.
> [Introduced][ce-19507] in GitLab 11.0.
For internal and private projects a [GitLab Deploy Token](../../user/project/deploy_tokens/index.md#gitlab-deploy-token)
will be automatically created, when Auto DevOps is enabled and the Auto DevOps settings are saved. This Deploy Token
can be used for permanent access to the registry.
If the GitLab Deploy Token cannot be found, `CI_REGISTRY_PASSWORD` is
used. Note that `CI_REGISTRY_PASSWORD` is only valid during deployment.
This means that Kubernetes will be able to successfully pull the
container image during deployment but in cases where the image needs to
be pulled again, e.g. after pod eviction, Kubernetes will fail to do so
as it will be attempting to fetch the image using
`CI_REGISTRY_PASSWORD`.
NOTE: **Note:**
When the GitLab Deploy Token has been manually revoked, it won't be automatically created.
