Installing Docker on Mac OS X
Note
: Docker is still under heavy development! We don't recommend using it in production yet, but we're getting closer with each release. Please see our blog post, Getting to Docker 1.0
Note: Docker is supported on Mac OS X 10.6 "Snow Leopard" or newer.
The Docker Engine uses Linux-specific kernel features, so we run it on OS X using a lightweight virtual machine. You can use the OS X Docker client to control the virtualized engine to build, run and manage Docker containers.
To make this process easier we designed a helper application called boot2docker to install the virtual machine and run the Docker daemon.
Installation
- Download the latest release of the Docker for OSX Installer
- Run the installer, which will install VirtualBox and the Boot2Docker management tool.
- Open a terminal and run:
boot2docker init
boot2docker start
export DOCKER_HOST=tcp://localhost:2375
boot2docker init
will ask you to enter an ssh key passphrase - the simplest
(but least secure) is to just hit [Enter]. This passphrase is used by the
boot2docker ssh
command.
Once you have an initialized virtual machine, you can boot2docker stop
and boot2docker start
it.
Upgrading
To upgrade:
- Download the latest release of the Docker for OSX Installer
- Run the installer, which will update VirtualBox and the Boot2Docker management tool.
- To upgrade your existing virtual machine, open a terminal and run:
boot2docker stop
boot2docker download
boot2docker start
Running Docker
From your terminal, you can try the “hello world” example. Run:
$ docker run ubuntu echo hello world
This will download the ubuntu
image and print hello world
.
Container port redirection
The latest version of boot2docker
sets up two network adapters: one using NAT
to allow the VM to download images and files from the Internet, and one host only
network adapter to which the container's ports will be exposed on.
If you run a container with an exposed port:
docker run --rm -i -t -p 80:80 apache
Then you should be able to access that Apache server using the IP address reported to you using:
boot2docker ssh ip addr show dev eth1
Typically, it is 192.168.59.103, but at this point it can change.
If you want to share container ports with other computers on your LAN, you will need to set up NAT adaptor based port forwarding
Further details
The Boot2Docker management tool provides some commands:
$ ./boot2docker
Usage: ./boot2docker [<options>]
{help|init|up|ssh|save|down|poweroff|reset|restart|config|status|info|delete|download|version}
[<args>]
Continue with the User Guide.
