• Install Docker on Linux : Recommended Option worked for me.
• Run docker in rootless mode on Linux : This is default on macOS

Documentation is quite detailed and clear. 💯

• List dockers container, images via docker ps -a. This lists all the containers even if they are stopped.
• docker ps shows only the running containers
• Remove images (To clean up disk space) using docker rm -f <name> (Name is the last column in docker ps output)
• docker <system/image/container/network> prune : Removed unused objects.
  • Use system option to "Remove all unused containers, networks, images (both dangling and unreferenced), and optionally, volumes."
