NEW QUESTION # 62
You have a Kubernetes cluster with multiple namespaces. You need to set up RBAC to allow a specific user, "developer", to only deploy and manage pods within the "dev" namespace, but restrict access to other resources.
Answer:
Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Create the following YAML files:
1. Role.yaml:
2. RoleBinding.yaml:
Solution (Step by Step) : 1 . Create the Role: Apply the 'Role.yamP file using 'kubectl apply -f Role.yamr. This defines the permissions granted to the role 'pod-manager-dev' within the 'dev' namespace. 2. Create the RoleBinding: Apply the 'RoleBinding.yaml' file using 'kubectl apply -f RoleBinding.yaml'. This binds the 'pod-manager-dev' role to the user 'developer' , allowing them to access resources defined in the role. 3. Verify Access: As the user 'developer' , try deploying a pod or managing deployments within the 'dev' namespace. Verify that the user has the necessary permissions. 4. Test Restrictions: Try accessing resources outside the 'dev' namespace or trying actions not defined in the role (e.g., creating a service in the 'dev' namespace). Verify that the user is denied access.
