How can you run more than one container in a single pod?

• A. Use a StatefulSet with a single Pod containing multiple containers
• B. Create two Pods and share the same volume
• C. Run a sidecar container in a separate Pod
• D. Define multiple containers in the Pod spec (spec.containers)

Answer: (D)

A Pod can host multiple containers that share the same network namespace and storage. To run more than one container in a single Pod, define multiple containers in the Pod spec (spec.containers). Each entry specifies a container image, resources, ports, and volume mounts, allowing the containers to coordinate via localhost and share volumes defined on the Pod. This pattern is common for a main application container plus a sidecar or helper container (for logging, metrics, etc.). The other options don’t fit because they either bring containers into separate Pods or rely on a controller/structure that isn’t about hosting multiple containers in one Pod.
