Kuma via Vagrant¶
Core developers run Kuma in a Vagrant-managed virtual machine so we can run the entire MDN stack. (Django, KumaScript, Search, Celery, etc.) If you’re on Mac OS X or Linux and looking for a quick way to get started, you should try these instructions.
At the end, you’ll earn the badge:
Install and run everything¶
Install VirtualBox 4.x from http://www.virtualbox.org/
(Windows) After installing VirtualBox you need to set PATH=C:\Program Files\Oracle\VirtualBox\VBoxManage.exe;
Install vagrant >= 1.6 using the installer from vagrantup.com
Install the vagrant-vbguest plugin.
Clone your fork of Kuma and update submodules:
git clone email@example.com:<your_username>/kuma.git cd kuma git submodule update --init --recursive
Copy a vagrantconfig_local.yaml file for your VM:
cp vagrantconfig_local.yaml-dist vagrantconfig_local.yaml
Start the VM and install everything. (approx. 30 min on a fast net connection).:
VirtualBox creates VMs in your system drive. Kuma’s VM is 3GB. If it won’t fit on your system drive, you will need to change that directory to another drive.
At the end, you should see:
=> default: notice: Finished catalog run in .... seconds
If the above process fails with an error, check Troubleshooting.
Add the hostnames to the end of your hosts file with this shell command:
echo '192.168.10.55 developer-local.allizom.org mdn-local.mozillademos.org' | sudo tee -a /etc/hosts
Log into the VM with ssh:
Use foreman inside the VM to start all site services:
You should see output like:
20:32:59 web.1 | started with pid 2244 20:32:59 celery.1 | started with pid 2245 20:32:59 kumascript.1 | started with pid 2246 20:32:59 stylus.1 | started with pid 2247 ...
Visit https://mdn-local.mozillademos.org and add an exception for the security certificate if prompted

You’ve installed Kuma! If you want the badge, email a screenshot of your browser to mdn-dev at mozilla dot com.
Create an admin user¶
You will want to make yourself an admin user to enable important site features.
Sign up/in with Persona
After you sign in, SSH into the vm and make yourself an admin:
vagrant ssh mysql -uroot kuma UPDATE auth_user set is_staff = 1, is_active=1, is_superuser = 1 WHERE username = 'YOUR_USERNAME';
You should see:
Query OK, 1 row affected (0.01 sec) Rows matched: 1 Changed: 1 Warnings: 0
Enable Important Site Features¶
You’ll need to use feature toggles to enable some basic features.
To enable GitHub authentication ...
- Application name: MDN (<username>)
- Homepage url: https://developer-local.allizom.org/docs/MDN/Contribute/Howto/Create_an_MDN_account
- Application description: My own GitHub app for MDN!
- Authorization callback URL: https://developer-local.allizom.org/users/github/login/callback/
Add a django-allauth social app for GitHub:
- Provider: GitHub
- Name: developer-local.allizom.org
- Client id: <your GitHub App Client ID>
- Secret key: <your GitHub App Client Secret>
- Sites: example.com -> Chosen sites
GitHub auth is also (temporarily) behind a waffle flag. So, add a waffle flag called github_login and set “Everyone” to “Yes”.
Now you can sign in with GitHub at https://developer-local.allizom.org
The central feature of MDN is wiki editing. We use a waffle flag called kumaediting to control edits to the wiki. So we can effectively put the site into “read-only” and/or “write-by-staff-only” modes.
To enable wiki editing on your MDN vm, add a waffle flag called kumaediting and set “Everyone” to “Yes”.
You can visit https://developer-local.allizom.org/docs/new to create new wiki pages as needed.
Many core MDN contributors create a personal User:<username> page as a testing sandbox.
Developing with Vagrant¶
Edit files as usual on your host machine; the current directory is mounted via NFS at /home/vagrant/src within the VM. Updates should be reflected without any action on your part.
See development for tips not specific to vagrant.
Useful vagrant sub-commands:
vagrant ssh # Connect to the VM via ssh vagrant suspend # Sleep the VM, saving state vagrant halt # Shutdown the VM vagrant up # Boot up the VM vagrant destroy # Destroy the VM
Errors during vagrant up¶
vagrant up starts the virtual machine. The first time you run vagrant up it also provisions the vm - i.e., it automatically installs and configures Kuma software on the vm. We provision the vm with puppet manifests in the puppet/manifests directory.
Sometimes we put puppet declarations in the wrong order. Which means some errors can be fixed by simply provisioning the vm again:
In some rare occasions you might need to run this multiple times. If you see the same error over and over, please ask for more help.
On Ubuntu, vagrant up might fail after being unable to mount NFS shared folders. First, make sure you have the nfs-common and nfs-server packages installed and also note that you can’t export anything via NFS inside an encrypted volume or home dir.
If that doesn’t help you can disable nfs by setting the nfs flag in the vagrantconfig_local.yaml file you just created.
Note: If you decide to run nfs: false, the system will be a lot slower. There is also the potential of running into weird issues with puppet, since the current puppet configurations do not currently support nfs: false.
If you have other problems during vagrant up, please ask for more help.
Errors after switching branches¶
You should occasionally re-run the Puppet setup, especially after updating code with major changes. This will ensure that the VM environment stays up to date with configuration changes and installation of additional services.
On the Host:
Inside the VM:
sudo puppet apply /home/vagrant/src/puppet/manifests/dev-vagrant.pp
