Can a docker container run multiple processes?

Also know, how many processes are there in a Docker container?
Beside above, can I have multiple CMD in Dockerfile? At all times, there can be only one CMD. You are right, the second Dockerfile will overwrite the CMD command of the first one. Docker will always run a single command, not more. So at the end of your Dockerfile, you can specify one command to run.
Regarding this, can we run multiple images in one container?
2 Answers. You cannot have "multiple images to run in one container", that wouldn't make sense. Then you would have to get all of them started automatically when the container starts. You can use a process manager such as supervisord (Docker documentation here).
Is Docker container a process?
When a Docker container is launched, it runs a single process. This process is usually the one that runs your application when you create containers per application. This very different from the traditional OS containers where you have multiple services running on the same OS.
