Running XNAT with Vagrant

In a matter of minutes, you can deploy a running copy of XNAT in a virtual machine, using Vagrant. For advanced users, you can also choose to setup one of multiple configurations for your XNAT VM. 


Additional Prerequisites for Windows Users

  • Bash terminal program - Git Bash is adequate and is included with the Git installer - this is what will be used for these instructions. You can also use  Cygwin , but it isn't as straightforward to use.
  • When installing Git, make sure to select to check-out as-is and commit with Unix line endings in your install options.  
  • Recommended SSH key management:  PuTTYPuTTYgen, and Pageant

Windows Vagrant Bug

As of this writing, there is a bug with Vagrant 1.8.5 for Windows that prevents the download of VM 'box' files during initialization of the VM. The curl.exe program that's included in Vagrant does not work properly. The workaround is to install Microsoft's Visual C++ 2010 Redistributable package BEFORE installing Vagrant (or uninstall Vagrant, install the Visual C++ package, and reinstall Vagrant). Another (somewhat hacky) option, if using Git Bash, you could replace Vagrant's curl.exe with the curl.exe program included with Git Bash:

cd /c/HashiCorp/Vagrant/embedded/bin
# backup Vagrant's curl.exe
mv curl.exe curlx.exe
cp /mingw64/bin/curl.exe curl.exe

Download XNAT Vagrant

There are a couple different ways to get the XNAT Vagrant project.

Install the xnat-vagrant Download Bundle

You can download the XNAT Vagrant project directly from our download repository:

Once you've downloaded the archive, unzip it using a standard zip utility. It will expand into a folder named xnat-vagrant. Proceed to Run the setup script.

Clone the xnat-vagrant Source Repository

Clone the xnat-vagrant repository to your local computer by logging into the Terminal, navigating to your desired folder location, then running the following command: 

git clone
git clone

Follow the instructions at to clone your repo. 

Another xnat-vagrant repo that is updated more often, and therefore possibly less stable, is available at . Clone the same way as above, but substitute the URL with the BitBucket value.

Configure and Customize XNAT Vagrant

The default properties for a particular configuration depend on the settings for that configuration. The available configurations can be found by looking in the configs folder under your xnat-vagrant project. As of this writing, the available configurations are:

Configuration Description
xnat Downloads a pre-built war file that can be deployed directly into Tomcat without going through the build process. The download is saved into a folder on the host computer so subsequent deployments don't require downloading the files again. However, you should download a new version if a new one has been released!
xnat-dev Maps a source code folder on the host computer to a folder inside the VM at /data/project/src/ build XNAT, where project is the name of the configured project (this is xnat by default; see below for information on changing the default settings).
xnat-latest Downloads and builds the XNAT source code inside the VM itself. This is the slowest of the standard XNAT 1.7 configurations (although still not too slow). Using this configuration is an easy way to download and evaluate the latest XNAT source code. This can be useful for troubleshooting build errors: if you are experiencing errors building locally, comparing these error with the xnat-latest build can help narrow down potential issues.

Builds a VM running a pre-built, pre-configured XNAT 1.6.5 system. This is useful for working with existing code that runs on 1.6.5 and hasn't been migrated to work with 1.7.0. 

XNAT does not need to be built in this VM - the box file that's used already has XNAT 1.6.5 built and running.

The settings for each configuration can be found in the file config.yaml in the configuration folder. For example, the settings for the xnat configuration are in the file configs/xnat/config.yaml

 For many purposes, you can simply use the default values for a configuration. If you do need to override values in a configuration's default settings, create a file named local.yaml in the configuration's folder. You can then define your own values for the available properties. There's a file named sample.local.yaml you can refer to as an example. You can also reference the config.yaml file to see all of the properties that are set and available to override.

For example, a common requirement is to specify an IP address compatible with the local network configuration, as well as increase the amount of RAM available to the VM. Looking in the config.yaml for the xnat configuration, these have the following default values:

ram:            2048 

Your local.yaml file might look like this:

ram:            4096 

When you run the script that actually creates your XNAT VM, the values in local.yaml override the values in config.yaml.

Create the XNAT Vagrant VM

Once you've downloaded the XNAT Vagrant project and set any custom properties required, you can create the VM one of three ways:

  • The master run script
  • The script for the specific configuration you want to create
  • Running the various vagrant commands manually

Master Run Script

The master run script is located in the top-level folder of the xnat-vagrant project. This script requires two arguments:

The available commands are:

  • setup
  • ssh
  • start
  • stop
  • destroy

start and stop are aliases for Vagrant's own reload and halt commands respectively and can be used to start and stop VMs that have completed setup.

From the xnat-vagrant folder:

./run xnat setup

This launches the setup script in the xnat configuration folder. The setup script automates downloading the XNAT war and pipeline installer archive, then executes a series of Vagrant commands to get the VM fully provisioned. You'll see a bunch of text fly up the console, and the script should ultimately exit with a success message that displays the URL where your new XNAT instance can be accessed with your web browser.

Configuration Script

Each configuration folder has its own script. For the most part, the master run script described in the previous section just invokes the script for the specified configuration. You can do this directly as well:

$ cd configs/xnat
$ ./

The advantage to using a configuration-specific script rather than the master run script is that being in the configuration folder makes it easier to work with your local.yaml to test settings and configurations for your VM.

Vagrant Commands

Finally you can run Vagrant commands directly within the configuration folders, with the main difference being you'll run 'vagrant reload' instead of 'vagrant up' after the initial setup. This is a more advanced option that can give you a great deal of control over how your VM is configured and created, but requires more knowledge over the specifics of configuring and running Vagrant. To find the commands used by the XNAT Vagrant project to build VMs, you should look through the script that most closely resembles the configuration you want to work with.

Work with the XNAT Vagrant VM

Once you've created an XNAT Vagrant VM, you can start to use the XNAT server there. There are a couple of steps you'll need to take to make this work:

  • Configure the VM's host and server name
  • Configure XNAT
  • Log into the VM to manage services

Configure Host and Server Name

You can access your server directly through the configured IP address. By default, this is set to This can be easily changed in local.yaml before creating the VM. If you're comfortable using the bare IP address, you don't need to worry about the host and server name.

If you'd like something more readable and memorable, you'll probably want to configure the host and server name. The server name, also known as the fully qualified domain name or FQDN, is the standard web address, something like The hostname is the first part of the FQDN, in this case images. To work with a custom host and server name, you need to make a couple of changes:

  • When customizing your VM configuration, add the name and server settings to your local.yaml configuration. The default value of name is xnat-dev so if you're OK with that as your host name, you don't need to override it. Note that name is also used to name the VM in the VirtualBox inventory, so it must be unique to the VMs running on your host server. You can also specify name and host separately: by default, host is set to the same value as name, but they can be different! The value for server should be set to the value you want for the FQDN:

    name:           xnatdev
  • Creating the VM with the host and server name won't help your host machine find the server. For this, your machine needs to have a way to associate the FQDN with the VM's IP address. The easiest way to do this is to configure the hosts file on your host machine. For most operating systems, this is located in the file /etc/hosts and requires root access to modify:

    $ sudo vim /etc/hosts 

    Windows also has a hosts file, but editing it can be trickier.

    Once you've opened the hosts file, you just need to add the line to associate the VM's IP address with the FQDN: 

    Save the hosts file and you're done. No services need to be restarted or reloaded for this change to take effect.

It's possible to configure a DNS server to point to the VM or even modify the VM's network configuration so that it gets its IP from a DHCP server which can7 then manage the host name resolution to the IP address, but that depends on your local network architecture and configuration and is outside of the scope of this documentation.

Initialize and Configure XNAT

Once you have your VM running and can reach the server through its IP address or FQDN, you can configure your XNAT system. This task is the same regardless of whether you're running a VM, installing on a server, or running on a local development instance. This is described in XNAT Setup - First Time Configuration.

Manage VM Services

If you use a particular VM for more than trivial or trial operations, you'll eventually want to be able to manage the VM itself, not just the XNAT it hosts. To access the VM through the command line, you can use the Vagrant ssh command from the configuration-specific folder. Once on the VM, you can run commands as the default user, which has access to the Tomcat server and XNAT data folders. For more secure operations, you can use the sudo command to get root access. The code below shows a sample set of operations.
