Setting up Vagrant

The following commands should be executed in your host machine’s console.

Vagrant is used to manage Ion’s development environment so that it closely resembles the production environment. To get started, download and install Virtualbox from here and Vagrant from here.

Ensure you have an SSH key set up with GitHub by running ssh -T You should be greeted by your username. If not, set up an SSH key with GitHub by following these instructions.

With Vagrant and Virtualbox installed, clone the Ion repository onto the host computer and cd into the new directory.

Note: if your host machine is running Windows, please run git config core.autocrlf input before cloning to prevent line ending issues.

$ git clone intranet
$ cd intranet

In the config directory, copy the file devconfig.json.sample to devconfig.json and edit the properties in devconfig.json as appropriate. Ensure ssh_key is set to the same SSH key registered with GitHub (e.g. id_rsa).

Run vagrant plugin install vagrant-vbguest If you are on Windows, also run vagrant plugin install vagrant-winnfsd

Run vagrant up && vagrant reload and wait while the development environment is set up.

If you are asked to select a network interface for bridging, enter the number corresponding to one that is active. To automatically select this interface in the future, set the “network_interface” key in devconfig.json to the name of the interface you selected (e.g. "en0: Wi-Fi (AirPort)").

There may be repeated warnings similar to “Remote connection disconnect and Warning: Connection aborted. Retrying... on the second vagrant up. After several minutes they will stop. Once the provisioning process is complete, run vagrant ssh to log in to the development box.

The following commands should be executed in your development box.

Move into the intranet directory and run workon ion to load the Python dependencies. workon ion should always be the first thing you run after you SSH into the development box.

The Git repository on the host computer is synced with ~/intranet on the virtual machine, so you can edit files within the repo on the host computer with a text editor of your choice and the changes will be immediately reflected on the virtual machine.

Continue with these post-install steps.


If you get a SIOCADDRT: Network is unreachable error when running vagrant up, you need to start the OpenVPN client.

If you see a Adding routes to host computer... message, you probably forgot to start the OpenVPN client.

If you get a message that begins with Vagrant failed to initialize at a very early stage, run the commands in this list in order until one of them succeeds and Vagrant works again:

  1. vagrant plugin update (updates all plugins)

  2. vagrant plugin repair (attempts to repair all plugins)

  3. vagrant plugin expunge --reinstall (removes and re-installs all plugins)

  4. If none of these work, see “If all else fails” below.

If all else fails

If Vagrant errors every time you try to do anything and either 1) a solution is not listed here or 2) the solution does not work, then follow these steps:

  1. Rename the .vagrant.d folder in your home directory to something else (which will effectively delete it from Vagrant’s perspective)

  2. Re-run the appropriate vagrant plugin install ... commands listed above.

  3. When they finish, Vagrant should work again. You should then be able to safely delete the old .vagrant.d directory.

If that doesn’t work, contact a senior Ion developer.
