Kubernetes Policies Explained: NetworkPolicy, Quotas & Limits (2026 Guide)
What happens if one application suddenly consumes all the CPU in your Kubernetes cluster?
Or if one Pod starts communicating with every service in the system?
This is where Kubernetes Policies become critical.
In this video, we explain how Kubernetes enforces rules using NetworkPolicy, ResourceQuota, and LimitRange.
You will learn:
• How ResourceQuota prevents teams from exhausting cluster resources
• How LimitRange enforces resource boundaries for containers
• How NetworkPolicy controls communication between Pods
• Why policies are essential for large multi-team Kubernetes clusters
