# Docker Machine  Machine lets you create Docker hosts on your computer, on cloud providers, and inside your own data center. 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 default Running pre-create checks... Creating machine... (default) Creating VirtualBox VM... (default) Creating SSH key... (default) Starting VM... Waiting for machine to be running, this may take a few minutes... Machine is running, waiting for SSH to be available... Detecting operating system of created instance... Detecting the provisioner... Provisioning with boot2docker... Copying certs to the local machine directory... Copying certs to the remote machine... Setting Docker configuration on the remote daemon... Checking connection to Docker... Docker is up and running! To see how to connect Docker to this machine, run: docker-machine env default $ docker-machine ls NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS default - virtualbox Running tcp://192.168.99.188:2376 v1.9.1 $ eval "$(docker-machine env default)" $ docker run busybox echo hello world Unable to find image 'busybox:latest' locally 511136ea3c5a: Pull complete df7546f9f060: Pull complete ea13149945cb: Pull complete 4986bf8c1536: Pull complete hello world ``` In addition to local VMs, you can create and manage cloud servers: ```console $ docker-machine create -d digitalocean --digitalocean-access-token=secret staging Creating SSH key... Creating Digital Ocean droplet... To see how to connect Docker to this machine, run: docker-machine env staging $ docker-machine ls NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS default - virtualbox Running tcp://192.168.99.188:2376 v1.9.1 staging - digitalocean Running tcp://203.0.113.81:2376 v1.9.1 ``` ## Installation and documentation Full documentation [is available here](https://docs.docker.com/machine/). ## Contributing Want to hack on Machine? Please start with the [Contributing Guide](https://github.com/docker/machine/blob/master/CONTRIBUTING.md). ## Driver Plugins In addition to the core driver plugins bundled alongside Docker Machine, users can make and distribute their own plugin for any virtualization technology or cloud provider. To browse the list of known Docker Machine plugins, please [see this document in our docs repo](https://github.com/docker/docker.github.io/blob/master/machine/AVAILABLE_DRIVER_PLUGINS.md). ## Troubleshooting Docker Machine tries to do the right thing in a variety of scenarios but sometimes things do not go according to plan. Here is a quick troubleshooting guide which may help you to resolve of the issues you may be seeing. Note that some of the suggested solutions are only available on the Docker Machine master branch. If you need them, consider compiling Docker Machine from source. #### `docker-machine` hangs A common issue with Docker Machine is that it will hang when attempting to start up the virtual machine. Since starting the machine is part of the `create` process, `create` is often where these types of errors show up. A hang could be due to a variety of factors, but the most common suspect is networking. Consider the following: - Are you using a VPN? If so, try disconnecting and see if creation will succeed without the VPN. Some VPN software aggressively controls routes and you may need to [manually add the route](https://github.com/docker/machine/issues/1500#issuecomment-121134958). - Are you connected to a proxy server, corporate or otherwise? If so, take a look at the `--no-proxy` flag for `env` and at [setting environment variables for the created Docker Engine](https://docs.docker.com/machine/reference/create/#specifying-configuration-options-for-the-created-docker-engine). - Are there a lot of host-only interfaces listed by the command `VBoxManage list hostonlyifs`? If so, this has sometimes been known to cause bugs. Consider removing the ones you are not using (`VBoxManage hostonlyif remove name`) and trying machine creation again. We are keenly aware of this as an issue and working towards a set of solutions which is robust for all users, so please give us feedback and/or report issues, workarounds, and desired workflows as you discover them. #### Machine creation errors out before finishing If you see messages such as "exit status 1" creating machines with VirtualBox, this frequently indicates that there is an issue with VirtualBox itself. Please [file an issue](https://github.com/docker/machine/issues/new) and include a link to a [Github Gist](https://gist.github.com/) with the output of the VirtualBox log (usually located at `$HOME/.docker/machine/machines/machinename/machinename/Logs/VBox.log`), as well as the output of running the Docker Machine command which is failing with the global `--debug` flag enabled. This will help us to track down which versions of VirtualBox are failing where, and under which conditions. If you see messages such as "exit status 255", this frequently indicates there has been an issue with SSH. Please investigate your SSH configuration if you have one, and/or [file an issue](https://github.com/docker/machine/issues). #### "You may be getting rate limited by Github" error message In order to `create` or `upgrade` virtual machines running Docker, Docker Machine will check the Github API for the latest release of the [boot2docker operating system](https://github.com/boot2docker/boot2docker). The Github API allows for a small number of unauthenticated requests from a given client, but if you share an IP address with many other users (e.g. in an office), you may get rate limited by their API, and Docker Machine will error out with messages indicating this. In order to work around this issue, you can [generate a token](https://help.github.com/articles/creating-an-access-token-for-command-line-use/) and pass it to Docker Machine using the global `--github-api-token` flag like so: ```console $ docker-machine --github-api-token=token create -d virtualbox newbox ``` This should eliminate any issues you've been experiencing with rate limiting.
