NEW QUESTION # 82

Answer:

Explanation:
See the solution below.
Explanation
kubectl create namespace development
kubectl run nginx --image=nginx --restart=Never -n development


NEW QUESTION # 83
You have a Kubernetes cluster with a 'default' namespace. You want to prevent any users from creating pods in this namespace.
Create a ClusterRole and ClusterRoleBinding to achieve this restriction.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
Step 1: Create a ClusterRole to deny pod creation in the 'default' namespace.

Step 2: Create a ClusterRoleBinding to apply the ClusterRole to all users.

We create a ClusterRole that specifically targets the 'default' namespace and denies 'create' permissions for pods. This ClusterRole uses 'resourceNames' and 'namespaceSelector& to precisely target the 'default' namespace. We create a ClusterRoleBinding that applies the ClusterRole to all users in the cluster. Applying the configurations: Use 'kubectl apply -f [filename].yaml' to apply the ClusterRole and ClusterRoleBinding YAML files. This will prevent anyone from creating pods in the 'default' namespace. This configuration is a powerful way to implement security policies and prevent unintended resource creation in sensitive namespaces. ,
