What is your experience with network plugins and their integration?

Experience with network plugins typically involves configuring and integrating solutions such as Calico, Flannel, Weave, or Cilium into Kubernetes or other container environments. For example, I have configured Calico to ensure network policy and isolation between pods, as well as integrated Flannel for simple overlay network communication.

During integration, it is important to consider the features of the chosen plugin: supported protocols, infrastructure requirements, and compatibility with CNI (Container Network Interface). This usually includes:

• Installing the plugin via manifests or Helm charts
• Configuring network policies and security rules
• Testing network communication between containers

An example of configuring Calico in Kubernetes (fragment of a manifest):

apiVersion: projectcalico.org/v3
kind: NetworkPolicy
metadata:
  name: allow-app
spec:
  selector: app == 'myapp'
  ingress:
  - action: Allow
    source:
      selector: role == 'frontend'

Such experience enables reliable and secure network communication in distributed systems.
