Challenge

Configure the `auth-gateway` Pod to Only Run on `k8s-worker2`

Locate the auth-gateway pod in the beebox-auth namespace. Modify the pod, using a label and a nodeSelector constraint, so it will always be scheduled on k8s-worker2. You will need to delete and re-create the pod in order for these changes to take effect.

You can find a YAML descriptor for this pod at /home/cloud_user/auth-gateway.yml.
Challenge

Configure the `auth-data` Deployment's Replica Pods to Only Run on `k8s-worker2`

You will find the auth-data deployment in the beebox-auth namespace. Modify the deployment, using a nodeSelector constraint, so its replica pods will always run on k8s-worker2. These changes should take effect once you make this change via a rolling deployment.

You can find a YAML descriptor for this pod at /home/cloud_user/auth-data.yml.
