Is the docker daemon running on macOs

To check if the Docker daemon is running on a Mac, you can follow these steps:

  • Open the Finder and navigate to the Applications folder.

  • In the Applications folder, find and open the Terminal app. This command-line int allows you to run commands on your Mac.

  • In the Terminal app, type the following command and press Enter to run it:

ps -ef | grep docker

This command will list all of the processes running on your Mac and filter the output to only show processes with the word "docker" in their name.

  1. If the Docker daemon is running, you should see output that includes a line similar to the following:

/usr/local/bin/docker -d

This indicates that the Docker daemon is running and listening for requests.

  1. If the Docker daemon is not running, you will not see any output from the command. In this case, you can start the Docker daemon by running the following command:

sudo systemctl start docker

This will start the Docker daemon and make it available to run Docker commands.

Note: these instructions are for Docker on macOS. The steps may vary slightly if you are using Docker on a different platform.
