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:
Complete instructions on how to deploy DevStack with Trove and Trove-Dashboard, please refer to the official OpenStack documentation.
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': ['10.2.100.133:11211', '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.
