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 LIBS_FROM_GIT+=,python-troveclient DATABASE_PASSWORD=password ADMIN_PASSWORD=password SERVICE_PASSWORD=password SERVICE_TOKEN=password RABBIT_PASSWORD=password LOGFILE=$DEST/logs/stack.sh.log VERBOSE=True LOG_COLOR=False LOGDAYS=1 IPV4_ADDRS_SAFE_TO_USE=10.111.0.0/26 FIXED_RANGE=10.111.0.0/26 NETWORK_GATEWAY=10.111.0.1 FLOATING_RANGE=172.30.5.0/24 PUBLIC_NETWORK_GATEWAY=172.30.5.1 # Pre-requisites ENABLED_SERVICES=rabbit,mysql,key # DVR Q_AGENT=ovn Q_ML2_PLUGIN_MECHANISM_DRIVERS=ovn,logger Q_ML2_PLUGIN_TYPE_DRIVERS=local,flat,vlan,geneve Q_ML2_TENANT_NETWORK_TYPE="geneve" enable_service ovn-northd enable_service ovn-controller enable_service q-ovn-metadata-agent # Use Neutron enable_service q-svc # Disable Neutron agents not used with OVN. disable_service q-agt disable_service q-l3 disable_service q-dhcp disable_service q-meta # Enable services, these services depend on neutron plugin. enable_plugin neutron https://opendev.org/openstack/neutron enable_service q-trunk enable_service q-dns enable_service q-port-forwarding enable_service q-qos enable_service neutron-segments enable_service q-log # Enable neutron tempest plugin tests enable_plugin neutron-tempest-plugin https://opendev.org/openstack/neutron-tempest-plugin # Compile if your distro kernel does not include ovs+conntrack support.

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.
