Please see octavia repository

Howto

Package the octavia_dashboard by running:
```
python setup.py sdist
```
This will create a python egg in the dist folder, which can be used to install on the horizon machine or within horizon's python virtual environment.

Copy _1482_project_load_balancer_panel.py in octavia_dashboard/enabled directory to openstack_dashboard/local/enabled:

$ cp -a \
  ${OCTAVIA_DASHBOARD_DIR}/octavia_dashboard/enabled/_1482_*.py \
  ${HORIZON_DIR}/openstack_dashboard/local/enabled/

(Optional) Generate the policy file and copy into horizon's policy files folder, and copy _1499_load_balancer_settings.py in octavia_dashboard/local_settings.d directory to openstack_dashboard/local/local_settings.d:

$ oslopolicy-policy-generator \
  --config-file \
  ${OCTAVIA_DIR}/etc/policy/octavia-policy-generator.conf \
  --output-file \
  ${OCTAVIA_DASHBOARD_DIR}/octavia_dashboard/conf/octavia_policy.yaml
$ cp -a \
  ${OCTAVIA_DASHBOARD_DIR}/octavia_dashboard/conf/octavia_policy.yaml \
  ${HORIZON_DIR}/openstack_dashboard/conf/
$ cp -a \
  ${OCTAVIA_DASHBOARD_DIR}/octavia_dashboard/local_settings.d/_1499_*.py \
  ${HORIZON_DIR}/openstack_dashboard/local/local_settings.d/

Django has a compressor feature that performs many enhancements for the delivery of static files. If the compressor feature is enabled in your environment (COMPRESS_OFFLINE = True), run the following commands:
```
$ ./manage.py collectstatic
$ ./manage.py compress
```
Finally restart your web server to enable octavia-dashboard in your Horizon:
```
$ sudo service apache2 restart
```

Enabling octavia-dashboard and neutron-lbaas-dashboard

In general we advise against having both dashboards running at the same time to avoid confusing users, which is exaggerated since the dashboards will have the same label.

In rare circumstances, e.g. as part of a migration strategy, it might be necessary to do so. The main issue to watch out for is to avoid neutron-lbaas and Octavia getting out of sync and neutron-lbaas-dashboard showing phantom load balancers - this can be avoided if the sync between Octavia and neutron-lbaas is fully enabled.

Here is a table to show some cases:

Configuration neutron-lbaas	Configuration Octavia	neutron-lbaas-dashboard enabled	octavia-dashboard enabled	Notes
not installed	v2 API enabled	not supported	preferred
octavia-driver	v2 API disabled v1 API enabled	supported	not supported	sync required
octavia-driver	v2 API enabled v1 API enabled	supported	preferred	sync required
octavia-proxy plugin	v1 API disabled v2 API enabled	Supported (but not recommended)	preferred
no octavia driver but other drivers	not installed	preferred	not supported
no octavia driver but other drivers	v2 API enabled v1 API disabled	preferred	preferred	independent services
