# Docker Machine
|
||
|
||
Machine makes it really easy to create Docker hosts on local hypervisors and cloud providers. It creates servers, installs Docker on them, then configures the Docker client to talk to them.
|
||
|
||
It works a bit like this:
|
||
|
||
```console
|
||
$ docker-machine create -d virtualbox dev
|
||
[info] Downloading boot2docker...
|
||
[info] Creating SSH key...
|
||
[info] Creating VirtualBox VM...
|
||
[info] Starting VirtualBox VM...
|
||
[info] Waiting for VM to start...
|
||
[info] "dev" has been created and is now the active host. Docker commands will now run against that host.
|
||
|
||
$ docker-machine ls
|
||
NAME ACTIVE DRIVER STATE URL
|
||
dev * virtualbox Running tcp://192.168.99.100:2375
|
||
|
||
$ docker $(docker-machine config dev) run busybox echo hello world
|
||
Unable to find image 'busybox' locally

|
||
hello world
|
||
|
||
$ docker-machine create -d digitalocean --digitalocean-access-token=... staging
|
||
[info] Creating SSH key...
|
||
[info] Creating Digital Ocean droplet...
|
||
[info] Waiting for SSH...
|
||
[info] "staging" has been created and is now the active host. Docker commands will now run against that host.
|
||
|
||
$ docker-machine ls
|
||
NAME ACTIVE DRIVER STATE URL
|
||
dev virtualbox Running tcp://192.168.99.108:2376
|
||
staging * digitalocean Running tcp://104.236.37.134:2376
|
||
```
|
||
|
||
Machine creates Docker hosts that are secure by default. The connection between the client and daemon is encrypted and authenticated using TLS security. To get the Docker arguments for a machine use the command: `docker-machine config <machine-name>` i.e. `docker-machine config dev`.
|
||
|
||
## Try it out
|
||
|
||
Machine is still in its early stages. If you'd like to try out a preview build, [download it here](https://github.com/docker/machine/releases/latest).

|
||
|
||
Want to hack on Machine? [Docker's contributions guidelines](https://github.com/docker/docker/blob/master/CONTRIBUTING.md) apply.
|
||
|
||
The requirements to build Machine are:
|
||
|
||
1. A running instance of Docker
|
||
2. The `bash` shell
|
||
|
||
To build, run:
|
||
|
||
$ script/build
|
||
|
||
From the Machine repository's root. Machine will run the build inside of a
|
||
Docker container and the compiled binaries will appear in the project directory
|
||
on the host.
|
||
|
||
By default, Machine will run a build which cross-compiles binaries for a variety
|
||
of architectures and operating systems. If you know that you are only compiling
|
||
for a particular architecture and/or operating system, you can speed up
|
||
compilation by overriding the default argument that the build script passes
|
||
to [gox](https://github.com/mitchellh/gox). This is very useful if you want
|
||
to iterate quickly on a new feature, bug fix, etc.
|
||
|
||
For instance, if you only want to compile for use on OSX with the x86_64 arch,
|
||
run:
|
||
|
||
$ script/build -osarch="darwin/amd64"
|
||
|
||
If you have any questions we're in #docker-machine on Freenode.
|
||
|
||
## Integration Tests
|
||
There is a suite of integration tests that will run for the drivers. In order
|
||
to use these you must export the corresponding environment variables for each
|
||
driver as these perform the actual actions (start, stop, restart, kill, etc).
|
||
|
||
By default, the suite will run tests against all drivers in master. You can
|
||
override this by setting the environment variable `MACHINE_TESTS`. For example,
|
||
`MACHINE_TESTS="virtualbox" ./script/run-integration-tests` will only run the
|
||
virtualbox driver integration tests.
|
||
|
||
To run, use the helper script `./script/run-integration-tests`.
