Synchronise with default enabled_filters: RetryFilter and RamFilter were removed from Nova. Also remove filters which were only required by earlier implementations of instance reservation. Change-Id: I7f60008d995266bda6d6880a952649f9b6477e3c

Installation without DevStack
|
|
=============================
|
|
|
|
This section includes instructions for Blazar installation.
|
|
You can use the host reservation and the instance reservation once
|
|
you finish the install guide.
|
|
|
|
Download all Blazar related repos:
|
|
|
|
.. sourcecode:: console
|
|
|
|
git clone https://opendev.org/openstack/blazar
|
|
git clone https://opendev.org/openstack/blazar-nova
|
|
git clone https://opendev.org/openstack/python-blazarclient
|
|
|
|
..
|
|
|
|
Install all these projects to your working environment via:
|
|
|
|
.. sourcecode:: console
|
|
|
|
python setup.py install
|
|
|
|
..
|
|
|
|
or
|
|
|
|
.. sourcecode:: console
|
|
|
|
python setup.py develop
|
|
|
|
..
|
|
|
|
Next you need to configure Blazar and Nova. First, generate a blazar.conf sample:
|
|
|
|
.. sourcecode:: console
|
|
|
|
cd /path/to/blazar
|
|
tox -e genconfig
|
|
mv etc/blazar/blazar.conf.sample /etc/blazar/blazar.conf
|
|
|
|
..
|
|
|
|
Then edit */etc/blazar/blazar.conf* using the following example:
|
|
|
|
.. sourcecode:: console
|
|
|
|
[DEFAULT]
|
|
host=<blazar_host>
|
|
port=<blazar_port>
|
|
os_auth_host=<auth_host>
|
|
os_auth_port=<auth_port>
|
|
os_auth_protocol=<http, for example>
|
|
os_auth_version=v3
|
|
os_admin_username=<username>
|
|
os_admin_password=<password>
|
|
os_admin_project_name=<project_name>
|
|
identity_service=<identity_service_name>
|
|
os_region_name=<region_name>
|
|
|
|
[manager]
|
|
plugins=physical.host.plugin,virtual.instance.plugin
|
|
|
|
[keystone_authtoken]
|
|
auth_type=<password, for example>
|
|
project_domain_name=<project_domain_name>
|
|
project_name=<project_name>
|
|
user_domain_name=<user_domain_name>
|
|
username=<username>
|
|
password=<password>
|
|
auth_url=<identity_service_url>
|
|
|
|
..
|
|
|
|
*os_admin_** flags refer to the Blazar service user. If you do not have this
|
|
user, create it:
|
|
|
|
.. sourcecode:: console
|
|
|
|
openstack user create --password <password> --project <project_name> --email <email-address> <username>
|
|
openstack role add --project <project_name> --user <username> <admin_role>
|
|
|
|
..
|
|
|
|
Next you need to configure Nova. Please add the following lines to nova.conf file:
|
|
|
|
.. sourcecode:: console
|
|
|
|
[filter_scheduler]
|
|
available_filters = nova.scheduler.filters.all_filters
|
|
available_filters = blazarnova.scheduler.filters.blazar_filter.BlazarFilter
|
|
enabled_filters = AvailabilityZoneFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter,ServerGroupAntiAffinityFilter,ServerGroupAffinityFilter,SameHostFilter,DifferentHostFilter,BlazarFilter
|
|
|
|
..
|
|
|
|
Restart nova-scheduler to use the new configuration file.
|
|
|
|
Next you need to create a Nova aggregate to use as a free pool for host
|
|
reservation:
|
|
|
|
.. sourcecode:: console
|
|
|
|
openstack aggregate create freepool
|
|
|
|
..
|
|
|
|
And we need to create the reservation service in Keystone with its endpoints:
|
|
|
|
.. sourcecode:: console
|
|
|
|
openstack service create --name blazar --description "OpenStack Reservation Service" reservation
|
|
openstack endpoint create --region <region> blazar admin "<auth_protocol>://<blazar_host>:<blazar_port>/v1"
|
|
openstack endpoint create --region <region> blazar internal "<auth_protocol>://<blazar_host>:<blazar_port>/v1"
|
|
openstack endpoint create --region <region> blazar public "<auth_protocol>://<blazar_host>:<blazar_port>/v1"
|
|
|
|
..
|
|
|
|
And, finally, we need to create a database for Blazar:
|
|
|
|
.. sourcecode:: console
|
|
|
|
mysql -u<user> -p<password> -h<host> -e "DROP DATABASE IF EXISTS blazar;"
|
|
mysql -u<user> -p<password> -h<host> -e "CREATE DATABASE blazar CHARACTER SET utf8;"
|
|
|
|
..
|
|
|
|
Then edit the database section of */etc/blazar/blazar.conf*:
|
|
|
|
.. sourcecode:: console
|
|
|
|
[database]
|
|
connection=mysql+pymysql://<user>:<password>@<host>/blazar?charset=utf8
|
|
|
|
..
|
|
|
|
To start Blazar services use:
|
|
|
|
.. sourcecode:: console
|
|
|
|
blazar-api --config-file /etc/blazar/blazar.conf
|
|
blazar-manager --config-file /etc/blazar/blazar.conf
|
|
|
|
..
|
|
|
|
Now you can use python-blazarclient to communicate with Blazar.
