--- description: Get started with Docker Machine and a local VM keywords: docker, machine, virtualbox, local title: Get started with Docker Machine and a local VM --- Let's take a look at using `docker-machine` to create, use and manage a Docker host inside of a local virtual machine. ## Prerequisite Information With the advent of [Docker for Mac](/docker-for-mac/index.md) and [Docker for Windows](/docker-for-windows/index.md) as replacements for [Docker Toolbox](/toolbox/overview.md), we recommend that you use these for your primary Docker workflows. You can use these applications to run Docker natively on your local system without using Docker Machine at all. (See [Docker for Mac vs. Docker Toolbox](/docker-for-mac/docker-toolbox.md) for an explanation on the Mac side.) However, if you want to create _multiple_ local machines, you need Docker Machine, which is still available to create and manage machines for power users or multi-node experimentation. Both Docker for Mac and Docker for Windows include the newest version of Docker Machine, so when you install either of these, you get `docker-machine`. The new solutions come with their own native virtualization solutions rather than Oracle VirtualBox, so keep the following considerations in mind when using Machine to create local VMs. * **Docker for Mac** - You can use `docker-machine create` with the `virtualbox` driver to create additional local machines. * **Docker for Windows** - You can use `docker-machine create` with the `hyperv` driver to create additional local machines. #### If you are using Docker for Windows Docker for Windows uses [Microsoft Hyper-V](https://msdn.microsoft.com/en-us/virtualization/hyperv_on_windows/windows_welcome) for virtualization, and Hyper-V is not compatible with Oracle VirtualBox. Therefore, you cannot run the two solutions simultaneously. But you can still use `docker-machine` to create more local VMs by using the Microsoft Hyper-V driver. * If you are using Docker for Windows, the only prerequisite is to have Docker for Windows installed. If you want to create multiple local machines, use the Microsoft `hyperv` driver to create them. (See the [Docker Machine driver for Microsoft Hyper-V](drivers/hyper-v.md).) #### If you are using Docker for Mac Docker for Mac uses [HyperKit](https://github.com/docker/HyperKit/), a lightweight macOS virtualization solution built on top of the [Hypervisor.framework](https://developer.apple.com/reference/hypervisor) in macOS 10.10 Yosemite and higher. Currently, there is no `docker-machine create` driver for HyperKit, so you will use `virtualbox` driver to create local machines. (See the [Docker Machine driver for Oracle VirtualBox](drivers/virtualbox.md).) Note that you can run both HyperKit and Oracle VirtualBox on the same system. To learn more, see [Docker for Mac vs. Docker Toolbox](/docker-for-mac/docker-toolbox/). * Make sure you have [the latest VirtualBox](https://www.virtualbox.org/wiki/Downloads){: target="_blank" class="_"} correctly installed on your system (either as part of an earlier Toolbox install, or manual install). #### If you are using Docker Toolbox Docker for Mac and Docker for Windows both require newer versions of their respective operating systems, so users with older OS versions must use Docker Toolbox. * If you are using Docker Toolbox on either Mac or an older version Windows system (without Hyper-V), you will use the `virtualbox` driver to create a local machine based on Oracle [VirtualBox(https://www.virtualbox.org/){: target="_blank" class="_"}. (See the [Docker Machine driver for Oracle VirtualBox](drivers/virtualbox.md).) * If you are using Docker Toolbox on a Windows system that has Hyper-V but cannot run Docker for Windows (for example Windows 8 Pro), you must use the `hyperv` driver to create local machines. (See the [Docker Machine driver for Microsoft Hyper-V](drivers/hyper-v.md).) * Make sure you have [the latest VirtualBox](https://www.virtualbox.org/wiki/Downloads){: target="_blank" class="_"} correctly installed on your system. If you used [Toolbox](https://www.docker.com/products/docker-toolbox){: target="_blank" class="_"} or [Docker for Windows](/docker-for-windows/index.md){: target="_blank" class="_"} to install Docker Machine, VirtualBox is automatically installed. * If you used the Quickstart Terminal to launch your first machine and set your terminal environment to point to it, a default machine was automatically created. If this is the case, you can still follow along with these steps, but create another machine and name it something other than "default" (e.g., staging or sandbox). ## Use Machine to run Docker containers To run a Docker container, you: * create a new (or start an existing) Docker virtual machine * switch your environment to your new VM * use the docker client to create, load, and manage containers Once you create a machine, you can reuse it as often as you like. Like any VirtualBox VM, it maintains its configuration between uses. The examples here show how to create and start a machine, run Docker commands, and work with containers. ## Create a machine 1. Open a command shell or terminal window. These command examples shows a Bash shell. For a different shell, such as C Shell, the same commands are the same except where noted. 2. Use `docker-machine ls` to list available machines. In this example, no machines have been created yet. $ docker-machine ls NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS 3. Create a machine. Run the `docker-machine create` command, pass the appropriate driver to the `--driver` flag and provide a machine name. If this is your first machine, name it `default` as shown in the example. If you already have a "default" machine, choose another name for this new machine. * If you are using Toolbox on Mac, Toolbox on older Windows systems without Hyper-V, or Docker for Mac, use `virtualbox` as the driver, as shown in this example. (The Docker Machine VirtualBox driver reference is [here](drivers/virtualbox.md).) (See [prerequisites](get-started.md#prerequisite-information) above to learn more.) * On Docker for Windows systems that support Hyper-V, use the `hyperv` driver as shown in the [Docker Machine Microsoft Hyper-V driver reference](drivers/hyper-v.md). (See [prerequisites](get-started.md#prerequisite-information) above to learn more.) $ docker-machine create --driver virtualbox default Running pre-create checks... Creating machine... (staging) Copying /Users/ripley/.docker/machine/cache/boot2docker.iso to /Users/ripley/.docker/machine/machines/default/boot2docker.iso... (staging) Creating VirtualBox VM... (staging) Creating SSH key... (staging) Starting the VM... (staging) Waiting for an IP... Waiting for machine to be running, this may take a few minutes...

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 This command downloads a lightweight Linux distribution ([boot2docker](https://github.com/boot2docker/boot2docker){: target="_blank" class="_"}) with the Docker daemon installed, and creates and starts a VirtualBox VM with Docker running. 4. List available machines again to see your newly minted machine. $ docker-machine ls NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS default * virtualbox Running tcp://192.168.99.187:2376 v1.9.1 5. Get the environment commands for your new VM. As noted in the output of the `docker-machine create` command, you need to tell Docker to talk to the new machine. You can do this with the `docker-machine env` command. $ docker-machine env default export DOCKER_TLS_VERIFY="1" export DOCKER_HOST="tcp://172.16.62.130:2376" export DOCKER_CERT_PATH="/Users//.docker/machine/machines/default" export DOCKER_MACHINE_NAME="default" # Run this command to configure your shell: # eval "$(docker-machine env default)" 6. Connect your shell to the new machine. $ eval "$(docker-machine env default)" **Note**: If you are using `fish`, or a Windows shell such as Powershell/`cmd.exe` the above method will not work as described. Instead, see [the `env` command's documentation](/machine/reference/env.md){: target="_blank" class="_"} to learn how to set the environment variables for your shell. This sets environment variables for the current shell that the Docker client will read which specify the TLS settings. You need to do this each time you open a new shell or restart your machine. You can now run Docker commands on this host. ## Run containers and experiment with Machine commands Run a container with `docker run` to verify your set up. 1. Use `docker run` to download and run `busybox` with a simple 'echo' command. $ docker run busybox echo hello world Unable to find image 'busybox' locally Pulling repository busybox e72ac664f4f0: Download complete 511136ea3c5a: Download complete df7546f9f060: Download complete e433a6c5b276: Download complete hello world 2. Get the host IP address. Any exposed ports are available on the Docker host’s IP address, which you can get using the `docker-machine ip` command: $ docker-machine ip default 192.168.99.100 3. Run a [Nginx](https://www.nginx.com/){: target="_blank" class="_"} webserver in a container with the following command: $ docker run -d -p 8000:80 nginx When the image is finished pulling, you can hit the server at port 8000 on the IP address given to you by `docker-machine ip`. For instance: $ curl $(docker-machine ip default):8000 Welcome to nginx!

You can create and manage as many local VMs running Docker as you please; just run `docker-machine create` again. All created machines will appear in the output of `docker-machine ls`. ## Start and stop machines If you are finished using a host for the time being, you can stop it with `docker-machine stop` and later start it again with `docker-machine start`. $ docker-machine stop default $ docker-machine start default ## Operate on machines without specifying the name Some `docker-machine` commands will assume that the given operation should be run on a machine named `default` (if it exists) if no machine name is specified. Because using a local VM named `default` is such a common pattern, this allows you to save some typing on the most frequently used Machine commands. For example: $ docker-machine stop Stopping "default".... Machine "default" was stopped. $ docker-machine start Starting "default"... (default) Waiting for an IP... Machine "default" was started. Started machines may have new IP addresses. You may need to re-run the `docker-machine env` command. $ eval $(docker-machine env) $ docker-machine ip 192.168.99.100 Commands that follow this style are: - `docker-machine config` - `docker-machine env` - `docker-machine inspect` - `docker-machine ip` - `docker-machine kill` - `docker-machine provision` - `docker-machine regenerate-certs` - `docker-machine restart` - `docker-machine ssh` - `docker-machine start` - `docker-machine status` - `docker-machine stop` - `docker-machine upgrade` - `docker-machine url` For machines other than `default`, and commands other than those listed above, you must always specify the name explicitly as an argument. ## Start local machines on startup In order to ensure that the Docker client is automatically configured at the start of each shell session, some users like to embed `eval $(docker-machine env default)` in their shell profiles (e.g., the `~/.bash_profile` file). However, this fails if the `default` machine is not running. If desired, you can configure your system to start the `default` machine automatically. Here is an example of how to configure this on macOS. Create a file called `com.docker.machine.default.plist` under `~/Library/LaunchAgents` with the following content: ``` EnvironmentVariables PATH /usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin Label com.docker.machine.default ProgramArguments /usr/local/bin/docker-machine start default RunAtLoad ``` You can change the `default` string above to make this `LaunchAgent` start any machine(s) you desire. ## Where to go next - Provision multiple Docker hosts [on your cloud provider](get-started-cloud.md) - [Understand Machine concepts](concepts.md) - [Docker Machine list of reference pages for all supported drivers](/machine/drivers/index.md) - [Docker Machine driver for Oracle VirtualBox](drivers/virtualbox.md) - [Docker Machine driver for Microsoft Hyper-V](drivers/hyper-v.md) - [`docker-machine` command line reference](reference/index.md)
