How to check if docker daemon is running?

Question

I am trying to create a bash utility script to check if a docker daemon is running in my server. Is there a better way of checking if the docker daemon is running in my serv

You have a utility called pgrep on almost all the Linux systems.

You can just do:

pgrep -f docker > /dev/null || echo "starting docker"

Replace the echo command with your docker starting command.
