With addition of pip_install on every node, we don't need to have pip_install as a meta dependency. Depends-On: If3412bb888ebb854874bbc43eb76bfcb3e4a7868 Depends-On: I79ff70c438b44753be2a93f004ebbc46de0a963d Change-Id: I4f58507546b6990003e9465851c8039de9eeb35c

|
The following cinder services are managed by the role:
|

|
* cinder-scheduler
|
|
|
|
By default, cinder API v1 and v2 are both enabled.

Dependencies

|
~~~~~~~~~~~~
|
|
|
|
This role needs pip >= 7.1 installed on the target host.
|
|
|
|
This role needs to have the following variables defined:
|
|
|
|
.. code-block:: yaml
|
|
|
|
# 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
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
.. literalinclude:: ../../examples/playbook.yml
|
|
:language: yaml
|
|
|
|
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 <https://github.com/Logan2211/ansible-haproxy-endpoints>`_
|
|
used by the openstack-ansible project.

|
Tags

|

|
|
|

|
|
