City architects evaluating Calico- or Cilium-style plugins ask which Kubernetes extension interface provides Pod network connectivity?
Select an answer to reveal the explanation.
Short Explanation
Pods need a network “road crew” on each node—that crew is the CNI plugin (Calico, Cilium, and friends). CSI is disks; CRI is how kubelet talks to the container runtime. Different bays in the same garage.
Full Explanation
The Container Network Interface (CNI) is the plugin model Kubernetes uses for Pod IP allocation and connectivity on nodes. Storage uses CSI and runtimes use CRI; those interfaces do not provide the Pod network fabric. Service/Endpoints objects consume networking but are not the CNI plugin layer itself.
