Think you can run Kubernetes without a CNI plugin? ๐ค Think again!
๐ฎ Myth: Kubernetes can function without a CNI (Container Network Interface) plugin.
โ
Reality: Kubernetes needs a CNI (Container Network Interface) plugin to function properly. Without one:
โ Pods canโt communicate across nodes.
โ kubectl exec and kubectl logs may stop working.
โ Pods might get stuck in ContainerCreating.
Think of it like setting up a phone system without any network providerโsure, you have the hardware, but no way to actually connect!
A CNI (Container Network Interface) plugin is essential for:
โ
Pod-to-pod communication across nodes
โ
Service discovery & load balancing
โ
IP address management for pods
Unless you rely on host networking (which isnโt scalable), a CNI plugin like Calico, Flannel, or Cilium is a must!
๐ก Moral of the story? Donโt overlook networkingโwithout a CNI, your Kubernetes cluster is just a bunch of isolated containers.
