OpenStack Dashboard plugin for Trove project

How to use with Horizon on server:

Use pip to install the package on the server running Horizon. Then either copy or link the files in trove_dashboard/enabled to openstack_dashboard/local/enabled. This step will cause the Horizon service to pick up the trove plugin when it starts.

How to use with devstack:

Add the following to your devstack local.conf file:

enable_plugin trove-dashboard https://opendev.org/openstack/trove-dashboard

Here is a full example of devstack local.conf file that includes the trove plugin:

[[local|localrc]]
RECLONE=False
HOST_IP=<your-host-ip-here>

enable_plugin trove https://opendev.org/openstack/trove
enable_plugin trove-dashboard https://opendev.org/openstack/trove-dashboard

To run unit tests:

./run_tests.sh

Editing Code

Apache

Make a change to trove-dashboard then goto to the horizon directory and compress the code with django and then restart apache.:

# rsync code to /opt/stack/trove-dashboard
# copy or link files from trove-dashboard/enabled/* to horizon/openstack_dashboard/local/enabled/
cd /opt/stack/horizon
python manage.py compress
python manage.py collectstatic --noinput
sudo service apache2 restart

Django

You can also speed up development time using the django test server instead of apache.:

/opt/stack/horizon/run_tests.sh --runserver

If you set COMPRESS_ENABLED and COMPRESS_OFFLINE to False in local_settings.py that allows you to bypass the compress and collectstatic as well.

Settings

The use of a cross-process cache such as Memcached is required.

Install Memcached itself and a Memcached binding such as python-memcached.

For a single horizon instance use the CACHES setting like the example below.:

CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
        'LOCATION': '127.0.0.1:11211',
    },
}

For multiple horizon instances behind a load balancer configure each instance to use the same cache like the example below.:

CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
        'LOCATION': [u'10.2.100.133:11211', u'10.2.100.134:11211'']
    },
}

NOTE:

As of the Mitaka release, the dashboard for trove is now maintained outside of the Horizon codebase, in this repository.
