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

[desk@cli] $ kubectl config use-context prod-account 

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 database.

1. Edit the existing Role bound to the Pod's ServiceAccount test-sa to only allow performing get operations, only on resources of type Pods.

2. Create a new Role named test-role-2 in the namespace database, which only allows performing update operations, only on resources of type statuefulsets.

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

Note: Don't delete the existing RoleBinding.

Context

This cluster uses containerd as CRI runtime.

Containerd's default runtime handler is runc. Containerd has been prepared to support an additional runtime handler, runsc (gVisor).

Task

Create a RuntimeClass named sandboxed using the prepared runtime handler named runsc.

Update all Pods in the namespace server to run on gVisor.
