CNI (Container Network Interface) - CI/CD Glossary Definition
CNI is the Container Network Interface, a standard for plugins that wire up pod networking: assigning IPs and connecting pods so they can reach each other across nodes. Calico, Cilium, and Flannel are common implementations.
Why it matters
Pods stuck in ContainerCreating with network errors usually mean the CNI plugin is missing or misconfigured on a node, so the kubelet cannot set up the pod sandbox.
