Which command stops a running container named my-httpd-container?

• A. sudo podman kill my-httpd-container
• B. sudo podman pause my-httpd-container
• C. sudo podman stop my-httpd-container
• D. sudo podman rm my-httpd-container

Answer: (C)

Stopping a running container gracefully is about telling the container to terminate its main process in a clean way, allowing any cleanup to happen. The command to do this sends a termination signal to the container’s main process (SIGTERM), giving it a chance to shut down properly; if the process doesn’t exit in the allotted time, it then sends a stronger signal (SIGKILL) to force termination. This approach preserves proper shutdown behavior, logs, and any cleanup routines the application may have. The other options don’t fit as well. The kill command forces termination more abruptly, which can skip cleanup and risk data loss. Pausing suspends all container processes but doesn’t actually stop the container, so it isn’t a true shutdown. Removing the container deletes it; you generally can’t remove a running container without stopping it first (and removing means you lose the container’s state and configuration).
