What are Kubernetes Network Policies and how do they work?
Kubernetes Network Policies are rules that control the traffic between pods. They define how groups of pods can communicate with each other and with other network endpoints.
Can you explain how to create a Network Policy?
To create a Network Policy, you define a YAML file specifying the pod selector, ingress, and egress rules. Then, apply it using kubectl apply -f <filename>.yaml
.
What are the default behaviors if no Network Policies are applied?
By default, if no Network Policies are applied, all pods can communicate with each other. Network Policies restrict this communication.
How do I test if my Network Policies are working?
You can test Network Policies by attempting to connect between pods that should be allowed or denied access based on your defined rules.
