  1. Challenge

    Create a PodSecurityPolicy to Prevent Privileged Containers

    1. Create a PodSecurityPolicy called nopriv-psp.
    2. Configure nopriv-psp to prevent the creation of Pods with privileged containers.

    Note: PodSecurityPolicy is already enabled in the cluster. You can find a skeleton manifest for the PodSecurityPolicy on the CLI server at /home/cloud_user/nopriv-psp.yml.

  2. Challenge

    Use the PodSecurityPolicy to Secure a Namespace

    1. Create a ServiceAccount in the hoth namespace called hoth-sa.
    2. Create an RBAC setup to use the PodSecurityPolicy.
    3. Create a ClusterRole called use-nopriv-psp that allows usage of the PodSecurityPolicy.
    4. Create a ClusterRoleBinding called hoth-sa-use-nopriv-psp to bind the ClusterRole to the ServiceAccount.

    Note: You can find skeleton manifests for these objects on the CLI Server at:

    • /home/cloud_user/hoth-sa.yml
    • /home/cloud_user/use-nopriv-psp.yml
    • /home/cloud_user/hoth-sa-use-nopriv-psp.yml

    You can test your setup using the Pod manifest at /home/cloud_user/luke.yml. The Pod should fail creation since it uses a privileged container.
