How to find the CMD command of a docker image?

Question

I have a docker image installed and I'd like to check what is its CMD command. Is there any cli command to do so? for example, I'd like it to tell me that this docker image CMD is ["rails","server"]

You can use the docker inspect command

docker inspect --format='{{.Config.Cmd}}' <image:tag>
docker inspect -f '{{.Config.Cmd}}' <image:tag>

That is used, for instance, to "list full command of running/stopped container in Docker".
