26.3 Running the Image in a Container

The image pulled from the registry is a fully operational image that is ready to run in a container without modification. To run the image, use the podman run command. In this case the –rm option will be specified to indicate that we want to run the image in a container, execute one command and then have the container exit. In this case, the cat tool will be used to output the content of the /etc/passwd file located on the container root filesystem:

$ podman run --rm fedora:latest cat /etc/passwd

bin:x:1:1:bin:/bin:/sbin/nologin

daemon:x:2:2:daemon:/sbin:/sbin/nologin

adm:x:3:4:adm:/var/adm:/sbin/nologin
