NEW QUESTION # 46
You are tasked with setting up a Kubernetes cluster for a company with a strict security policy. They have two different teams: Development and Operations, with distinct access requirements.
The Development team needs read-only access to all resources and the ability to create and manage deployments, pods, and services. The Operations team needs full access to all resources, including cluster management, and the ability to perform actions like scaling, rolling updates, and troubleshooting.
Design a role-based access control (RBAC) configuration using Kubernetes resources (Role, RoleBinding, ClusterRole, ClusterRoleBinding) to grant appropriate access to each team.

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
Step 1: Create a Role for the Development team:

Step 2: Create a RoleBinding for the Development team:

Step 3: Create a ClusterRole for the Operations team:

Step 4: Create a ClusterRoleBinding for the Operations team:

The Role for the Development team grants specific permissions to create, manage, and view deployments, pods, and services. It also grants read-only access to all other resources. The RoleBinding links the "dev-role" to the "dev-user" account, allowing them to perform actions as defined by the Role. The ClusterRole for the Operations team provides full access to all cluster resources and allows them to perform any action, including cluster management tasks. The ClusterRoleBinding links the "ops-clusterrole" to the "ops-user" account, granting them complete control over the cluster. Note: You can replace "dev-user" and "ops-user" with actual user names or service accounts.
