LIP-Computing.nova-compute-node

Role Name

This role installs and configures a openstack nova compute node. This role allows to make a all-in installation, so that, it installs the compute node in a host which has already installed an openstack controller (installing LIP-Computing.os-controller).

Requirements

Disable SELinux (reboot is required).
Ensure the system has configured swap memory

Role Variables

openstack_all_in: True or False, indicates all-in installation (*) 
s.
openstack_version: "liberty" version is supported
openstack_controller_host: controller hostname
openstack_compute_node_host: compute node hostname
openstack_cidr: openstack internal network CIDR
openstack_compute_node_ip: controller ip
openstack_controller_ip: compute node ip (can be the same as controller in all-in installation)

#Rabbitmq variables
openstack_rabbit_host: rabbit_host ("{{ openstack_controller_host }}" by default)
openstack_rabbit_user: rabbit_user (openstack by default)
openstack_rabbit_pass: rabbit password ("{{ openstack_admin_password }}" by default)

openstack_admin_vip: administration IP ("{{ openstack_controller_host }}" by default)
openstack_os_identity_api_version: identity api version (3 by default)
openstack_ath_uri: auth_uri, authorization uri ("http://{{ openstack_admin_vip }}:5000" by default)
openstack_ath_url: auth_url, authorization url ("http://{{ openstack_admin_vip }}:35357" by default)

openstack_nova_keystone_password: nova keystone password ("{{ openstack_admin_password }}" by default)
openstack_neutron_keystone_password: neutron keystone password ("{{ openstack_admin_password }}" by default)    
openstack_keystone_auth_region: region_name (RegionOne by default)

openstack_neutron_bridge_interface: external bridge of openvswitch ("br-ex" by default)

(*) The openstack-all-in variable indicates installation all-in (controller and compute node in same host). If true it will make a minimal installation, because the host already should have most of the required packages.

Playbook Examples

This is an example of all-in installation. We install the compute node in a machine with openstack controller installed.
