The command "sudo podman run -v /conf:/etc/httpd/conf -d do180/apache" primarily does which of the following?

• A. Copies /conf from host to container
• B. Mounts the host directory /conf as /etc/httpd/conf inside the container
• C. Creates a container in detached mode with image do180/apache
• D. Exposes port 80 to the host

Answer: (B)

The key idea is bind-mounting a host directory into the container. The -v /conf:/etc/httpd/conf portion tells Podman to bind the host directory /conf to the path /etc/httpd/conf inside the container, so the container uses that host directory for its configuration and any changes there are reflected on the host. The -d flag just runs the container in detached mode (in the background); it’s an extra behavior, not the mounting action. This command doesn’t copy files (that would require a copy operation) and doesn’t expose ports (that would need port mapping like -p 80:80). Also, the host directory must exist for the bind mount to succeed.
