Is the docker daemon running?.
See 'docker run --help'.

If you try to execute the Docker run command in Terminal and you get the above error, then it's because Docker Desktop is not running.

1. Go to Spotlight Search,
2. Type: Docker and open the App
3. You would see it on your Apple Menu bar,
4. Make sure you see: "Docker is running"
   
   Make sure docker is running
