Install Docker on MacOS via Homebrew

(Adapted from a blog post by Yuta Fujii, https://medium.com/@yutafujii_59175/a-complete-one-by-one-guide-to-install-docker-on-your-mac-os-using-homebrew-e818eb4cfc3). These instructions have been tested on MacOS version 10.14.6 with Homebrew version 2.4.3. YMMV.

  • Install homebrew

      /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

  • Backup your Homebrew configuration (see https://tomlankhorst.nl/brew-bundle-restore-backup/)

      brew tap Homebrew/bundle
  brew bundle dump

    save the Brewfile someplace safe, in case you later need to restore your Homebrew system to its last-known-good state.

  • Install Docker:

      brew install docker docker-machine
  brew cask install virtualbox
  docker-machine create --driver virtualbox default
  docker-machine env default
  eval "$(docker-machine env default)"

    Note that the brew cask install virtualbox command may require you to enter a password, and will probably require you to go into the System Preferences application => Security preference panel, where you will need to click on Allow next to Oracle.

  • Test your Docker installation:

      docker run hello-world

    which should respond with:

   Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash

Share images, automate workflows, and more with a free Docker ID:
https://hub.docker.com/

Shut down the Docker server

docker-machine stop default

Restart the Docker server

docker-machine start default
eval "$(docker-machine env default)"
