The following steps work fine on macOS Sierra 10.12.4. Note that after brew installs Docker, the docker
command (symbolic link) is not available at /usr/local/bin
. Running the Docker app for the first time creates this symbolic link. See the detailed steps below.
Install Docker.
brew cask install docker
Launch Docker.
Docker
to launch Docker.When Docker is launched in this manner, a Docker whale icon appears in the status menu. As soon as the whale icon appears, the symbolic links for docker
, docker-compose
, docker-credential-osxkeychain
and docker-machine
are created in /usr/local/bin
.
$ ls -l /usr/local/bin/docker*
lrwxr-xr-x 1 susam domain Users 67 Apr 12 14:14 /usr/local/bin/docker -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker
lrwxr-xr-x 1 susam domain Users 75 Apr 12 14:14 /usr/local/bin/docker-compose -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-compose
lrwxr-xr-x 1 susam domain Users 90 Apr 12 14:14 /usr/local/bin/docker-credential-osxkeychain -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-credential-osxkeychain
lrwxr-xr-x 1 susam domain Users 75 Apr 12 14:14 /usr/local/bin/docker-machine -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-machine
Click on the docker whale icon in the status menu and wait for it to show Docker is running.
Test that docker works fine.

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.
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

If you are going to use docker-machine
to create virtual machines, install VirtualBox.
brew cask install virtualbox
Note that if VirtualBox is not installed, then docker-machine
fails with the following error.
$ docker-machine create manager
Running pre-create checks...
Error with pre-create check: "VBoxManage not found. Make sure VirtualBox is installed and VBoxManage is in the path"
