OpenStack Dashboard Configuration Guide

Sahara UI panels are integrated into the OpenStack Dashboard repository. No additional steps are required to enable Sahara UI in OpenStack Dashboard. However there are a few configurations that should be made to configure OpenStack Dashboard.

Dashboard configurations are applied through the local_settings.py file. The sample configuration file is available here.

1. Networking

Depending on the Networking backend (Nova Network or Neutron) used in the cloud, Sahara panels will determine automatically which input fields should be displayed.

While using Nova Network backend the cloud may be configured to automatically assign floating IPs to instances. If Sahara service is configured to use those automatically assigned floating IPs the same configuration should be done to the dashboard through the SAHARA_AUTO_IP_ALLOCATION_ENABLED parameter.

Example:

SAHARA_AUTO_IP_ALLOCATION_ENABLED = True

2. Different endpoint

Sahara UI panels normally use data-processing endpoint from Keystone to talk to Sahara service. In some cases it may be useful to switch to another endpoint, for example use locally installed Sahara instead of the one on the OpenStack controller.

To switch the UI to another endpoint the endpoint should be registered in the first place.

Local endpoint example:

openstack service create --name sahara_local --description \
    "Sahara Data Processing (local installation)" \
    data_processing_local

openstack endpoint create --region RegionOne \
--publicurl http://127.0.0.1:8386/v1.1/%\(tenant_id\)s \
--adminurl http://127.0.0.1:8386/v1.1/%\(tenant_id\)s \
--internalurl http://127.0.0.1:8386/v1.1/%\(tenant_id\)s \
data_processing_local

Then the endpoint name should be changed in sahara.py under the module of sahara-dashboard/sahara_dashboard/api/sahara.py.

# "type" of Sahara service registered in keystone
SAHARA_SERVICE = 'data_processing_local'
