Testing Horizon git snapshots

Testing horizon git checkouts

One of the cool things in Horizon is, one can easily try newest things out. This assumes, you already have an OpenStack installation available somewhere.

If you haven't already installed git:

yum install git

To clone horizons upstream git repository, run the command

git clone https://github.com/openstack/horizon
cd horizon
cp openstack_dashboard/local/local_settings.py.example openstack_dashboard/local/local_settings.py

Then please edit the file openstack_dashboard/local/local_settings.py and adjust

ALLOWED_HOSTS = ['*']

...

OPENSTACK_HOST = "127.0.0.1"

OPENSTACK_HOST has to point to your keystone instance, in this case to 127.0.0.1.

The development server requires a dependencies. If you didn't already install them, just run:

yum install gcc python-devel python-virtualenv openssl-devel libffi-devel which

To start your development server:

./run_tests.sh -m collectstatic

This will install all required dependencies in a virtual env inside your horizon directory. Horizon spreads static files like images and javascript files all around in its source tree. collectstatic will collect them and place those files in under a directory named static inside the horizon checkout. When running the development server, they will be served from that location.

Finally

./run_tests.sh --runserver

will start your Horizon instance from your git checkout. It can be accessed via http://<ip>:8000, in most cases, that is http://localhost:8000 .

Updating your checkout

The following snippet will pull in latest changes from git, will copy changed static files to the right places and will run your django development server. .. code-block:: bash

git fetch && git pull ./run_tests.sh -m collectstatic ./run_tests.sh --runserver
