Because these teams are working on different products, they should be given different access to the Kubernetes cluster.
First, we create a Role object named `role-blue`, where we define the actions that can be performed on specific Kubernetes resources.
Open Policy Agent is a general-purpose policy engine that unifies policy enforcement across the stack.
Administrators can define policies that instruct Kubernetes to limit the resources such as memory or CPU that containers or namespaces can consume, approve only containers based on images from specific registries, restrict NodePort service creation, or enforce standard naming.
By default, Kubernetes uses a flat network structure allowing any Pod to communicate with other Pods or Services in the cluster.
With RBAC, OPA, and network policies in place, you can protect your Kubernetes cluster by assuring that contributors have the proper access, that security policies are enforced, and that the network is tightly secured.
