질문 # 52
You are managing a Kubernetes cluster with a team of developers. You need to ensure that each developer only has access to the resources they need. For example, Developer A can only access the 'frontend' namespace and deploy applications there.
Developer B can access the 'backend' namespace and manage deployments and services.
Developer C can access the 'monitoring' namespace and access only read-only access to pods and services.
Define the RBAC rules and create the necessary Role, RoleBinding, and ServiceAccount resources to achieve this access control policy.
정답：
설명：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1 . Create ServiceAccounts for each Developer:
kubectl create serviceaccount dev-a -n frontend
kubectl create serviceaccount dev-b -n backend
kubectl create serviceaccount dev-c -n monitoring
2. Create Roles for each Developer:
For Developer A:
For Developer B:
For Developer C:
3. Create RoleBindings: For Developer A:
For Developer B:
For Developer C:

질문 # 54
You have a Kubernetes cluster with a service account named "my-sa" in the "my-namespace" namespace. You need to grant the service account the ability to read and write secrets in the "my-namespace" namespace and the ability to create pods in that namespace.
Create a Role and RoleBinding to achieve this using kubectl commands.
정답：
설명：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1 . Create the Role: Use the following command to create a role called 'sa-secret-pod-writer' in the 'my- namespace' namespace:
kubectl create role sa-secret-pod-writer--namespace=my-namespace --verb=get--verb=list --verb=watch verb=create --verb=update --verb=delete --verb=patch --resource=secrets --resource=pods --api-groups=""
2. Create the RoleBinding: Bind the role to the service account using the following command:
kubectl create rolebinding sa-secret-pod-writer-binding --namespace=my-namespace --role=sa-secret-pod- writer --serviceaccount=my-namespace:my-sa
3. Verify Access: Try running a pod using the service account "my-sa" in the "my-namespace" namespace. You should be able to successfully create the pod and access secrets within the namespace. You can test this by creating a pod definition with the 'serviceAccountName: my-sa' and include a volume mount to a secret within the "my-namespace" namespace.,
