An IT department has a service running in a container that must be reachable from external clients. Which approach helps route inbound requests from a specific address on the host to the container’s internal process, allowing external consumers to access it?
Assigning a host interface that listens on a designated address and forwards inbound traffic to the container’s internal interface
Configuring default gateway routes inside the container for external traffic
Passing host IP details to the container’s environment variables for address resolution
Implementing persistent volumes to store incoming requests until processing occurs
Port mapping connects external traffic to a container by linking an internal service address with a host listener. Assigning a host interface to listen on a designated address directs requests correctly to the container’s service. The other approaches rely on routing or storage mechanisms that do not forward inbound traffic to the container’s networking stack.
