CKS Exam Dumps : Certified Kubernetes Security Specialist (CKS)

Create a network policy named allow-np, that allows pod in the namespace staging to connect to port 80 of other pods in the same namespace.

Ensure that Network Policy:-

1. Does not allow access to pod not listening on port 80.

2. Does not allow access from Pods, not in namespace staging.

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.
