The container process on the host machine

Question

I am using Docker and want to determine which processes are running on containers. So, I ran this command in my container, which will use almost 100% of the CPU.

md5sum /dev/urandom

After that, I checked the processes using htopthe main machine.

How can I tell if this command is running inside the container instead of the host?

Answer 3

Another option is to run the command in the container:

docker exec <container> ps ax

This list should list the processes running in the container.
