Solution (Step by Step) :
I). Create a Role:
- Define a new Role named 'my-app-log-reader' that grants access to read logs of the 'my-app' pod.
- This role will be bound to the ServiceAccount used by the 'my-app' Deployment.

2. Create a RoleBinding: - Create a RoleBinding named 'my-app-log-reader-binding' to link the 'my-app-log-reader' Role to the 'my-app-sa' ServiceAccount. - This binding allows the 'my-app-sa' to use the permissions defined in the 'my-app-log-reader' role.

3. Apply the Configurations: - Apply the Role and RoleBinding YAML files to your Kubernetes cluster using 'kubectl apply -f role.yamr and 'kubectl apply -f rolebinding_yamr 4. verify the RBAC: - Once applied, you can verify the RBAC configuration by using 'kubectl auth can-i get pods --as=my-app-sa --namespace=' - This command should show 'yes' indicating that the ServiceAccount can access pods. - You can also check for access to logs with a similar command: 'kubectl auth can-i get pods/my-app-pod-name --namespace=' - Replace "my-app-pod-name' with the actual pod name of the application. 5. Test Access: - Try accessing the logs using "kubectl logs my-app-pod-name -n ' while impersonating the ServiceAccount 'my-app-sa' - You should be able to view the logs successfully. If any user tries to access the logs without the necessary permissions, they will be denied. Important Note: This is a basic example and can be further Kustomize d depending on your specific security needs. You can adjust the 'rules' in the Role definition to control specific permissions for users or ServiceAccounts. For example, you might restrict access to certain namespaces or resources. ]
