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.

Add the following to your devstack local.conf file:

enable_plugin trove-dashboard git://git.openstack.org/openstack/trove-dashboard

./run_tests.sh

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

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.

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'']

},

}

The following optional settings provide a way to override the default volume sizes provided in the new instance and new cluster dialogs:

• TROVE_DEFAULT_CLUSTER_VOL_SIZE
• TROVE_DEFAULT_VOL_SIZE

The following setting will ask the user to enter a database name when creating an instance with an Oracle datastore

• TROVE_ENABLE_ORACLE_DATABASE_NAME_VALIDATION = True

The following setting provides a way to enable backup of a single instance of a cluster. Set the value as a list of datastores names. For example, TROVE_CLUSTER_DATASTORES_ALLOWING_BACKUP = ["mongodb", "pxc"]

• TROVE_CLUSTER_DATASTORES_ALLOWING_BACKUP

The following setting provides a way to enable specifying user roles for a datastore. Set the value as a list of datastores names. For example, TROVE_ENABLE_USER_ROLES = ["couchbase"]

• TROVE_ENABLE_USER_ROLES

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