Install Docker using Homebrew
There is no doubt that Docker containers have revolutionized the way we develop and deploy applications. They provide developers with the ability to package applications and dependencies in an isolated environment.
Recently, we've seen widespread adoption of Docker as the ultimate containerization platform. Because of this, setting up Docker on all platforms has been greatly simplified, including macOS and Windows.
Install Docker on macOS using Homebrew
Docker supports the latest versions of macOS, including macOS Big Sur, macOS Monterey, and macOS Catalina. Docker provides a local application that we can install in Applicationsthe directory and /usr/local/bincreate a symbolic link in .
Install Docker using Homebrew. It is an open source package management system that we can use to install applications on macOS.
Homebrew installs packages to their directories and then symlinks their files to /usr/local. Homebrew can be installed by running the following command in a terminal.
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
Now that Homebrew is installed, to install Docker, execute the following command.
brew cask install docker
This command downloads dockerthe package, runs the Docker installer, and opens the GUI to set up the configuration. Use the following command to verify that the installation was successful.
docker --version
As mentioned earlier, Homebrew installs packages to their directories and then symlinks their files to /usr/local(on macOS Intel). However, after Brew installs Docker, /usr/local/binyou may not be able to use the docker command (symlink) in .
To resolve this issue, follow the steps below.
-
Press ⌘+ Spaceto open
Spotlight Searchand enterDockerto start Docker. -
In

Once we have started Docker, a whale-like icon should now be visible in the status menu. This means that all the symbol files pointing to the location of Docker have been
/usr/local/bincorrectly set up in . -
You can confirm this by executing the following command in your terminal.
Code:
$ ls -l /usr/local/bin/docker*
Now click on the Docker icon and wait for Docker to start.
Finally, we will run the following command to test if your Docker installation is set up correctly.
$ docker run hello-world
Output:
We have pulled the image from the Docker registry hello-worldand successfully created a Docker container using this command. This means that Docker is now properly set up in your system.
