     In a Kubernetes Pod, an infrastructure or "pause" container is first created to host the container endpoint. Containers that belong to the same pod, including infrastructure and worker containers, share a common network namespace and endpoint (same IP and port space). Pause containers are needed to accommodate worker containers crashing or restarting without losing any of the networking configuration.
