Installation guide

This page includes instructions for Blazar installation.

Download all Blazar related repos:

   git clone https://github.com/openstack/blazar.git
   git clone https://github.com/openstack/blazar-nova.git
   git clone https://github.com/openstack/python-blazarclient.git

Install all these projects to your working environment via:

   python setup.py install

or

   python setup.py develop

Next you need to configure Blazar and Nova. Define /etc/climate/climate.conf file using the following example:

[DEFAULT]

host=<blazar_host>

os_auth_host=<auth_host>
os_auth_port=<auth_port>
os_auth_protocol=<http, for example>
os_admin_username=<username>
os_admin_password=<password>
os_admin_tenant_name=<tenant_name>

[manager]
plugins=basic.vm.plugin,physical.host.plugin

[virtual:instance]
on_start=on_start
on_end = create_image, delete

[physical:host]
on_start=on_start
on_end = on_end
climate_username=<username>
climate_password=<password>
climate_tenant_name=<tenant_name>

[database]
connection=<path_to_blazar.sqlite>

Here os_admin_* flags refer to Blazar service user. climate_* ones - to admin user created specially to work with physical reservations. If you have no these users, create them via Keystone:

keystone user-create --name=climate --pass=<service_password> --tenant_id=<service_tenant_id> --email=climate@example.com
keystone user-role-add --tenant-id <service_tenant_id> --user-id <climate_user> --role-id <admin_role>

And the same procedure for special admin user to work with physical reservations.

Next you need to configure Nova. Note that virtual reservations (aka instance reservations) are not supported anymore because of incompatibility with new Nova releases.

If you want to use physical reservations add these ones:

scheduler_available_filters = nova.scheduler.filters.all_filters
scheduler_available_filters = climatenova.scheduler.filters.climate_filter.ClimateFilter
scheduler_default_filters=RetryFilter,AvailabilityZoneFilter,RamFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter,ClimateFilter

Restart nova-scheduler to use the new configuration file.

Blazar uses Keystone trusts to commit actions on behalf of user created lease. That’s why we need to create identityv3 service with appropriate endpoints:

keystone service-create --name keystonev3 --type identityv3 --description "Keystone Identity Service v3"
keystone endpoint-create --region <region> --service keystonev3 --publicurl "<auth_protocol>://<auth_host>:5000/v3" --adminurl "<auth_protocol>://<auth_host>:35357/v3" --internalurl "<auth_protocol>://<auth_host>:5000/v3"

And, finally, we need to create reservation service in Keystone with its endpoints:

keystone service-create --name climate --type reservation --description “OpenStack reservation service.”
keystone endpoint-create --region <region> --service climate --publicurl "<auth_protocol>://<climate_host>:1234/v1" --adminurl "<auth_protocol>://<climate_host>:1234/v1"

To start Blazar services use:

blazar-api
blazar-manager

Now you can use python-blazarclient to communicate with Blazar.
