If you want to support both Docker Toolbox and Docker for Mac, check out the Docker Version Manager (DVM).Docker is an open-sourced project that uses containers instead of virtual machines to run server applications. This may also happen if you use Docker Universal Control Plane (UCP). Running docker version in a command shell displays the version of the client and server you have on your system.

If you already have Docker Toolbox, and then you install Docker for Mac, you may get a newer version of the Docker client. You want the Docker client and Engine to match versions mismatches can cause problems where the client and host cannot communicate.

Multiple Docker Versionsĭocker for Mac replaces docker and docker-compose with its own versions if you already have Docker Toolbox on your Mac, Docker for Mac still replaces the binaries. If you use a shell script to set the Docker environment variables every time you open a command window (Terminal), you need to unset the variables every time you use Docker for Mac (alternately, you can write a shell script to follow behind and unset the variables).

You can upgrade your OS to the most recent viable version, provided your system supports it. Unfortunately, if you do not run “Mountain Lion” or later, you cannot run Docker for Mac.

The macOS Docker client talks to the Docker host VM, and your containers run on the host. On macOS, Docker’s daemon runs inside a Linux VM. On an “out-of-the-box” Linux installation, the Docker client, daemon, and all containers run directly on localhost, meaning you can access ports on a Docker container using localhost addressing something like localhost:8080 or 0.0.0.0:8376. Take a few minutes to understand some key concepts before you install Docker. You must not have a VirtualBox installation earlier than version 4.3.30 on your system.OS X 10.10.3 Yosemite or newer (or macOS).

2010 or newer, with Intel’s hardware Memory Management Unit (MMU).

Docker Machineĭocker for Mac does not affect previous machines created via Docker Machine, The installation gives you the option to copy containers and images from your local default machine if you have one. When you want to use a VirtualBox VM you have set up with docker-machine, simply run eval $(docker-machine env default) (assuming you want to target the machine “default”). When you use Docker for Mac, you need to unset all of your environment variables, using one of the methods above. You can run both Docker Toolbox and Docker for Mac on the same system, but not at the same time. Running Docker Toolbox and Docker for Mac on the same host When you run env | grep DOCKER now, you should see no output. If you use Bash, you can use unset $ to unset all of the Docker environment variables (this does not work in other shells, like zsh or csh).
