Which command starts a container in detached mode with image rhscl/httpd-24-rhel7:2.4-36.8?

• A. sudo podman run -it rhscl/httpd-24-rhel7:2.4-36.8
• B. sudo podman run -d rhscl/httpd-24-rhel7:2.4-36.8
• C. sudo podman run --name httpd -d rhscl/httpd-24-rhel7:2.4-36.8
• D. sudo podman run -d -t rhscl/httpd-24-rhel7:2.4-36.8

Answer: (B)

Detached mode means the container runs in the background, not attached to your terminal, and the -d flag is used to start it that way. The command that uses -d with the image rhscl/httpd-24-rhel7:2.4-36.8 starts the container in the background immediately and is the simplest way to achieve the requirement. Other options try to run in interactive mode (-it), which would keep the container attached to your terminal, or add a name (--name) in addition to detaching; while that extra option isn’t incorrect, the most straightforward way to meet the request is the command that includes only -d and the image. You can verify the container is running in detached mode by using podman ps.
