What are the differences between Kubernetes network policies and traditional firewalls?

What are the differences between Kubernetes network policies and traditional firewalls?

Kubernetes network policies are specific to Kubernetes environments, controlling traffic between pods, while traditional firewalls manage traffic at the network level, often for entire networks or servers.

Can you explain how Kubernetes network policies are implemented?

Sure! Kubernetes network policies are implemented using YAML configuration files that define rules for ingress and egress traffic between pods.

Are there any limitations to using Kubernetes network policies?

Yes, Kubernetes network policies only work with compatible network plugins, and they may not cover all security aspects like traditional firewalls.

How do I choose between using a network policy and a firewall?

It depends on your architecture. Use network policies for pod-to-pod communication within Kubernetes and firewalls for broader network security.
