Manage Kubernetes Security and RBAC for CKA
In this lab, you'll practice with Role Based Access Control (RBAC) to restrict the operations the different K8S users can perform. You will allow Pods to access the kube-apiserver and also prevent Pods from getting created when they don't meet certain policies. You will also use Secrets to securely manage sensitive data within your cluster. When you're finished, you'll have the required skills to securely manage the data, users and processes running in your clusters.

Get Started in the Lab Environment
Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!

Challenge
Use RBAC to Limit User Permissions
To start the lab, you'll understand the differences between Roles and ClusterRoles. You will also create RBAC policies to limit the access an user has over the cluster's resources.

Challenge
Allow a Pod to Communicate with the API Server
In this challenge you will create a Service Account and give it permissions to create Pods. You will then run a Pod using your new Service Account and ensure it can authenticate against the Kubernetes API Server to create Pods.

Challenge
Enforce Security Standards While Creating Pods
You now will look into applying Pod Security Standards to your namespaces. You will understand and implement the required changes in your Pod definition to ensure the security standards are met.

Challenge
Store Secrets in Kubernetes
Finally, you will use Kubernetes Secrets to manage and store the sensitive information within our cluster. In particular, you will be securing the password used by a MySQL database.
