In order to isolate and only display relevant CPU and Memory metrics for a given environment, GitLab needs a method to detect which containers it is running. Because these metrics are tracked at the container level, traditional Kubernetes labels are not available.
Instead, the [Deployment](https://kubernetes.io/docs/concepts/workloads/controllers/deployment/) or [DaemonSet](https://kubernetes.io/docs/concepts/workloads/controllers/daemonset/) name should begin with [CI_ENVIRONMENT_SLUG](../../../../ci/variables/README.md#predefined-variables-environment-variables). It can be followed by a `-` and additional content if desired. For example, a deployment name of `review-homepage-5620p5` would match the `review/homepage` environment.
