Cluster: scanner

Master node: controlplane

Worker node: worker1

You can switch the cluster/configuration context using the following command:

[desk@cli] $ kubectl config use-context scanner 

Given:

You may use Trivy's documentation.

Task:

Use the Trivy open-source container scanner to detect images with severe vulnerabilities used by Pods in the namespace nato.

Look for images with High or Critical severity vulnerabilities and delete the Pods that use those images.

Trivy is pre-installed on the cluster's master node. Use cluster's master node to use Trivy.

Context

A PodSecurityPolicy shall prevent the creation of privileged Pods in a specific namespace.

Task

Create a new PodSecurityPolicy named prevent-psp-policy,which prevents the creation of privileged Pods.

Create a new ClusterRole named restrict-access-role, which uses the newly created PodSecurityPolicy prevent-psp-policy.

Create a new ServiceAccount named psp-restrict-sa in the existing namespace staging.

Finally, create a new ClusterRoleBinding named restrict-access-bind, which binds the newly created ClusterRole restrict-access-role to the newly created ServiceAccount psp-restrict-sa.

Context

A Role bound to a Pod's ServiceAccount grants overly permissive permissions. Complete the following tasks to reduce the set of permissions.

Task

Given an existing Pod named web-pod running in the namespace security.

Edit the existing Role bound to the Pod's ServiceAccount sa-dev-1 to only allow performing watch operations, only on resources of type services.

Create a new Role named role-2 in the namespace security, which only allows performing update

operations, only on resources of type namespaces.

Create a new RoleBinding named role-2-binding binding the newly created Role to the Pod's ServiceAccount.
