Question

A developer is building a Pod that runs a main web server container alongside a logging sidecar container that must read the same log files the web server writes and reach the web server on localhost. Which statement correctly describes how these two containers behave within the same Pod?

Accepted Answer

They share the same network namespace and can communicate over localhost, and they can share files through a volume mounted into both containers.

Answer

Each container gets its own IP address, so the sidecar must use the web server's Service DNS name to reach it.

Answer

Containers in a Pod cannot share files at all; the sidecar must pull the logs over the network from the web server.

Answer

The two containers are scheduled independently and may land on different nodes, so localhost communication is unreliable.
