# Installing Docker on Mac OS X
|
|
|
|
> **Note:**
|
|
> Docker is supported on Mac OS X 10.6 "Snow Leopard" or newer.
|
|
|
|
The Docker Engine uses Linux-specific kernel features, so to run it on OS X
|
|
we need to use a lightweight virtual machine (vm). You use the OS X Docker client to
|
|
control the virtualized Docker Engine to build, run, and manage Docker containers.
|
|
|
|
To make this process easier, we've designed a helper application called
|
|
[Boot2Docker](https://github.com/boot2docker/boot2docker) that installs the
|
|
virtual machine and runs the Docker daemon.
|
|
|
|
## Demonstration

## Installation
|
|
|
|
1. Download the latest release of the [Docker for OS X Installer](
|
|
https://github.com/boot2docker/osx-installer/releases)
|
|
|
|
2. Run the installer, which will install VirtualBox and the Boot2Docker management
|
|
tool.
|
|
|
|
|
|
3. Run the `Boot2Docker` app in the `Applications` folder:
|
|
|
|
|
|
Or, to initialize Boot2Docker manually, open a terminal and run:
|
|
|
|
$ boot2docker init
|
|
$ boot2docker start
|
|
$ export DOCKER_HOST=tcp://$(boot2docker ip 2>/dev/null):2375
|
|
|
|
Once you have an initialized virtual machine, you can control it with `boot2docker stop`
|
|
and `boot2docker start`.
|
|
|
|
## Upgrading
|
|
|
|
1. Download the latest release of the [Docker for OS X Installer](
|
|
https://github.com/boot2docker/osx-installer/releases)
|
|
|
|
2. Run the installer, which will update VirtualBox and the Boot2Docker management
|
|
tool.
|
|
|
|
3. To upgrade your existing virtual machine, open a terminal and run:
|
|
|
|
$ boot2docker stop
|
|
$ boot2docker download
|
|
$ boot2docker start
|
|
|
|
## Running Docker
|
|
|
|
From your terminal, you can test that Docker is running with a “hello world” example.
|
|
Start the vm and then run:
|
|
|
|
$ docker run ubuntu echo hello world
|
|
|
|
This should download the `ubuntu` image and print `hello world`.
|
|
|
|
## Container port redirection
|
|
|
|
The latest version of `boot2docker` sets up a host only network adaptor which provides
|
|
access to the container's ports.
|
|
|
|
If you run a container with an exposed port,
|
|
|
|
$ docker run --rm -i -t -p 80:80 nginx
|
|
|
|
then you should be able to access that Nginx server using the IP address reported by:
|
|
|
|
$ boot2docker ip
|
|
|
|
Typically, it is 192.168.59.103, but it could get changed by Virtualbox's DHCP
|
|
implementation.
|
|
|
|
# Further details
|
|
|
|
If you are curious, the username for the boot2docker default user is `docker` and the password is `tcuser`.
|
|
|
|
The Boot2Docker management tool provides several commands:
|
|
|
|
$ ./boot2docker
|
|
Usage: ./boot2docker [<options>]
|
|
{help|init|up|ssh|save|down|poweroff|reset|restart|config|status|info|ip|delete|download|version} [<args>]
|
|
|
|
