Which command runs a container in detached mode with image rhscl/httpd-24-rhel7?

• A. sudo podman run -it rhscl/httpd-24-rhel7
• B. sudo podman run --name my-httpd-container -d rhscl/httpd-24-rhel7
• C. sudo podman run -d --name httpd -p 80:80 rhscl/httpd-24-rhel7
• D. sudo podman run -d rhscl/httpd-24-rhel7

Answer: (D)

Running a container in detached mode means it starts in the background and returns control to you. In Podman, you achieve this with the -d option on podman run. To use the image rhscl/httpd-24-rhel7 and start it detached, you simply specify -d and the image name. The command sudo podman run -d rhscl/httpd-24-rhel7 does exactly that: it launches the container in the background using that image and prints the container ID. You won’t get an attached shell, unlike with an interactive option. Adding a name or port mappings is optional and not required to meet the detached requirement, so the straightforward form is the best fit here.
