Have you ever had to raise the network layer in Kubernetes?

Yes, I have worked with the network layer in Kubernetes. This usually involves configuring CNI (Container Network Interface) plugins such as Calico, Flannel, or Weave.

The tasks included:

• Setting up network policies to restrict traffic between pods.
• Diagnosing network interaction issues, such as when pods cannot see each other.
• Configuring routing and IP addressing within the cluster.

For example, to ensure security, we configured Network Policies to allow traffic only between certain services, which helped isolate application components.
