Cinder role for OpenStack-Ansible

This Ansible role installs and configures OpenStack cinder.

The following cinder services are managed by the role:

cinder-api
cinder-volume
cinder-scheduler

By default, cinder API v1 and v2 are both enabled.

configure-cinder.rst

To clone or view the source code for this repository, visit the role repository for os_cinder.

Default variables

../../defaults/main.yml

Dependencies

This role needs pip >= 7.1 installed on the target host.

This role needs to have the following variables defined:

# Comma separated list of Glance API servers
cinder_glance_api_servers: "http://glance_server:9292"

# Hostname or IP address of the Galera database
cinder_galera_address: "1.2.3.4"

This list is not exhaustive at present. See role internals for further details.

Example playbook

../../examples/playbook.yml

External Restart Hooks

When the role performs a restart of the service, it will notify an Ansible handler named Manage LB, which is a noop within this role. In the playbook, other roles may be loaded before and after this role which will implement Ansible handler listeners for Manage LB, allowing external roles to manage the load balancer endpoints responsible for sending traffic to the servers being restarted by marking them in maintenance or active mode, draining sessions, etc. For an example implementation, please reference the ansible-haproxy-endpoints role used by the openstack-ansible project.
