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.
Note
If you have problems getting vagrant up, check Errors below.
Install VirtualBox >= 4.2.x from http://www.virtualbox.org/
Note
(Windows) After installing VirtualBox you need to set
PATH=C:\\Program Files\\Oracle\\VirtualBox\\VBoxManage.exe;
- Install vagrant >= 1.7 using the installer from vagrantup.com
Install Ansible on your machine so that Vagrant is able to set up the VM the way we need it.
See the Ansible Installation docs for which way to use on your computer's platform.
The most common platforms:
Mac OS X:
brew install ansible
or if you have a globally installed pip:
sudo pip install ansible
Ubuntu:
$ sudo apt-get install software-properties-common $ sudo apt-add-repository ppa:ansible/ansible $ sudo apt-get update $ sudo apt-get install ansible
Fedora / RPM-based distribution:
$ sudo dnf install ansible.noarch
For previous versions based on yum, use:
$ sudo yum install ansible.noarch
Windows:
Installation on Windows is complicated but we strive to make it easier in the future. Until then see this blog post for how to Run Vagrant with Ansible Provisioning on Windows
- Fork the project. (See GitHub <https://help.github.com/articles/fork-a-repo#step-1-fork-the-spoon-knife-repository>)
Clone your fork of Kuma and update submodules:
git clone git@github.com:<your_username>/kuma.git cd kuma git submodule update --init --recursive
Start the VM and install everything. (approx. 15 minutes on a fast net connection).:
vagrant up
Note
VirtualBox creates VMs in your system drive. Kuma's VM is approx. 2GB. 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:
Finished catalog run in .... seconds
If the above process fails with an error, check Errors.
Log into the VM with ssh:
vagrant ssh
Use
foreman
inside the VM to start all site services:foreman start
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.
- Visit the homepage at https://developer-local.allizom.org
You've installed Kuma!

All of the pure Python dependencies are included in the git repository, in the vendor
subdirectory. This allows them to be available on the Python path without needing to be installed in the system, allowing multiple versions for multiple projects simultaneously.
There are a small number of compiled packages, including the MySQL Python client. You can install these using pip
or via a package manager. To use pip
, you only need to do the following.
First SSH into the Vagrant VM:
vagrant ssh
Then disable the virtualenv that is auto-enabled and install the compiled dependencies:
deactivate
sudo pip install -r requirements/compiled.txt
If you'd like to change the way Vagrant works, we've added a few configuration values that may be worthwhile to look at. In case something doesn't suffice for your machine, please let us know!
To change the config values, simply create a dotenv file (.env
) in the directory (/home/vagrant/src/.env
in the Vagrant VM) and write <KEY>=<VALUE>
for each configuration variable you'd like to set.
Here's the configuration variables that are available for Vagrant:
VAGRANT_NFS
Default: true (Windows: false) Whether or not to use NFS for the synced folder.
VAGRANT_MEMORY_SIZE
The size of the Virtualbox VM memory in MB. Default: 2048
VAGRANT_CPU_CORES
The number of virtual CPU core the Virtualbox VM should have. Default: 2
VAGRANT_IP
The static IP the Virtualbox VM should be assigned to. Default: 192.168.10.55
VAGRANT_GUI
Whether the Virtualbox VM should boot with a GUI. Default: false
VAGRANT_ANSIBLE_VERBOSE
Whether the Ansible provisioner should print verbose output. Default: false
A possible /home/vagrant/src/.env
file could look like this for example:
VAGRANT_MEMORY_SIZE=4096
VAGRANT_CPU_CORES=4
VAGRANT_ANSIBLE_VERBOSE=true
Start by creating a file named settings_local.py
, and putting this line in it:
from settings import *
Now you can copy and modify any settings from settings.py
into settings_local.py
and the value will override the default.
Note
For some basic features you'll need to use feature toggles <feature-toggles>
to enable them.
At a minimum, you will need to define a database connection. An example configuration is:
DATABASES = {
'default': {
'NAME': 'kuma',
'ENGINE': 'django.db.backends.mysql',
'HOST': 'localhost',
'PORT': '3306',
'USER': 'kuma',
'PASSWORD': 'kuma',
'OPTIONS': {
'sql_mode': 'TRADITIONAL',
'charset': 'utf8',
'init_command': 'SET '
'storage_engine=INNODB,'
'character_set_connection=utf8,'
'collation_connection=utf8_general_ci',
},
'ATOMIC_REQUESTS': True,
'TEST': {
'CHARSET': 'utf8',
'COLLATION': 'utf8_general_ci',
},
},
}
Note the two values CHARSET
and COLLATION
of the TEST
setting. Without these, the test suite will use MySQL's (moronic) defaults when creating the test database (see below) and lots of tests will fail. Hundreds.
Once you've set up the database, you can generate the schema with Django's migrate
command:
./manage.py migrate
This will generate an empty database, which will get you started!
If you want to see images and have the pages formatted with CSS you need to set your settings_local.py
with the following:
DEBUG = True
TEMPLATE_DEBUG = DEBUG
SERVE_MEDIA = True
Setting DEBUG = False
will put the installation in production mode and ask for minified assets. In that case, you will need to generate CSS from stylus and compress resource:
./scripts/compile-stylesheets
./manage.py compress_assets
To enable KumaScript (Kuma's template system):
- Sign in
- Visit the constance config admin panel
- Change
KUMASCRIPT_TIMEOUT
to 600 - Click "Save" at the bottom
KumaScript is now enabled. You will also want to import the KumaScript auto-loaded modules. You can simply copy & paste them from the production site to your local site at the same slugs. Or you can email the dev-mdn@lists.mozilla.org list to get a .json file to load in your local django admin interface as described in this comment.
One of the packages Kuma uses, Django Mozilla Product Details, needs to fetch JSON files containing historical Firefox version data and write them to disk. To set this up, just run:
./manage.py update_product_details
...to do the initial fetch or run it again to update it.
To enable GitHub authentication ...
Register your own OAuth application on GitHub:
- 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
Now you can sign in with GitHub at https://developer-local.allizom.org/
Add the following to settings_local.py
so that Persona works with the development instance:
SITE_URL = 'http://localhost:8000'
PROTOCOL = 'http://'
DOMAIN = 'localhost'
PORT = 8000
SESSION_COOKIE_SECURE = False # needed if the server is running on http://
SESSION_EXPIRE_AT_BROWSER_CLOSE = False
The SESSION_EXPIRE_AT_BROWSER_CLOSE
setting is not strictly necessary, but it's convenient for development.
To prevent error messages like Forbidden (CSRF cookie not set.):
, you need to set your settings_local.py
with the following:
CSRF_COOKIE_SECURE = False
To start the dev server, run ./manage.py runserver
, then open up http://localhost:8000
. If everything's working, you should see the MDN home page!
You might need to first set LC_CTYPE
if you're on Mac OS X until bug 754728 is fixed:
export LC_CTYPE=en_US
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 (exchange
<< YOUR_USERNAME >>
with the username you used when signing up for Persona):vagrant ssh mysql -ukuma -pkuma kuma -e "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
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.
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 <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
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 in the VM. We provision the VM with Ansible roles in the provisioning directory.
Sometimes we put Ansible roles in the wrong order. Which means some errors can be fixed by simply provisioning the VM again:
vagrant provision
In some rare occasions you might need to run this multiple times. If you find an error that is fixed by running vagrant provision
again, please email us the error at dev-mdn@lists.mozilla.org and we'll see if we can fix it.
If you see the same error over and over, please ask for more help <more-help>
.
If you see errors that have "Django database migrations" in their title try to manually run them in the VM to see more about them. To do so:
vagrant ssh
python manage.py migrate
If you get an error, please ask for more help <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. On Windows NFS won't be used ever by the way.
If that doesn't help you can disable NFS by setting the VAGRANT_NFS
configration value in a .env
file. See the Vagrant configuration
<vagrant-config>
options for more info.
If you have other problems during vagrant up
, please check Troubleshooting <troubleshooting>
