Freezer - Horizon Dashboard

Requirements

Freezer Freezer Dashboard requires a freezer API client to be installed in the same environment as horizon:

pip install parsedatetime>=1.4
git clone https://github.com/openstack/freezer
cd freezer
python setup.py install (is important that freezer is installed from source and not with pip and
                         is installed on horizon virtual environment)

Freezer Dashboard requires a freezer API endpoint which you can install following this steps:

https://github.com/openstack/freezer-api/blob/master/README.rst

API registration

Register freezer api endpoint:

https://github.com/openstack/freezer-api/blob/master/README.rst#3-api-registration

If keystone service-create and endpoint-create are not available you can set as a fallback the following on:

# vim /opt/stack/horizon/openstack_dashboard/local/local_settings.py

# add FREEZER_API_URL = http://<api_url>:<port>

Dev Installation

In the installation procedure we'll assume your main Horizon dashboard directory is /opt/stack/horizon/openstack_dashboard/dashboards/.

To install freezer dashboard for development you need to do the following:

# git clone https://github.com/openstack/freezer-web-ui

# cd freezer-web-ui

# cp _50_freezer.py  /opt/stack/horizon/openstack_dashboard/enabled

# modify _50_freezer.py (line 9) and point the path to the freezer repo.

# cd /opt/stack/horizon/

# pip install -r requirements.txt

# make sure freezer is installed from source as detailed in the first step

# ./run_tests.sh --runserver 0.0.0.0:8000

Production Installation

To deploy freezer dashboard in production you need to do the following:

# git clone https://github.com/openstack/freezer-web-ui

# cd freezer-web-ui

# cp _50_freezer.py  /opt/stack/horizon/openstack_dashboard/enabled/

# restart apache2 service

A new tab called "Disaster Recovery" will be on your panels.

Running the unit tests

1. Create a virtual environment:

   virtualenv --no-site-packages -p /usr/bin/python2.7 .venv

2. Activate the virtual environment:

   . ./.venv/bin/activate

3. Install the requirements:

   pip install -r test-requirements.txt

4. Run the tests:

   python manage.py test . --settings=freezer_ui.tests.settings

Test coverage

1. Collect coverage information:

   coverage run --source='.' --omit='.venv/*' manage.py test . --settings=freezer_ui.tests.settings

2. View coverage report:

   coverage report

Tox

1. Run tox:

   tox -v

Development under proxy

If you are developing or deploying under proxies remember to set no_proxies for:
