Mark Goddard 80a32c3c74 cinder: restart services after upgrade
This patch is roughly an adaptation of
Ia6fc9011ee6f5461f40a1307b72709d769814a79 for cinder.

During an upgrade, cinder pins the version of RPC calls to the minimum
seen across all services. This ensures that old services do not receive
data they cannot handle. After the upgrade is complete, all cinder
services are supposed to be reloaded to cause them to check again the
RPC versions of services and use the new latest version which should now
be supported by all running services.

There is a second issue in that it takes some time for the upgraded
services to update the cinder services database table with their new
version. We need to wait until all cinder services have done this
before the restart is performed, otherwise the RPC version cap will
remain in place. There is currently no interface in cinder available for
checking these versions, so as a workaround we use a configurable
delay with a default duration of 30 seconds, as we do for nova.

This change restarts all cinder services after an upgrade, after a 30
second delay.

Kolla Ansible

image

The Kolla Ansible is a deliverable project separated from Kolla project.

Kolla Ansible deploys OpenStack services and infrastructure components in Docker containers.

Kolla's mission statement is:

To provide production-ready containers and deployment tools for operating
OpenStack clouds.

Kolla is highly opinionated out of the box, but allows for complete customization. This permits operators with little experience to deploy OpenStack quickly and as experience grows modify the OpenStack configuration to suit the operator's exact requirements.

Getting Started

Learn about Kolla Ansible by reading the documentation online Kolla Ansible.

Get started by reading the Developer Quickstart.

OpenStack services

Kolla Ansible deploys containers for the following OpenStack projects:

Infrastructure components

Kolla Ansible deploys containers for the following infrastructure components:

Directories

  • ansible - Contains Ansible playbooks to deploy OpenStack services and infrastructure components in Docker containers.
  • contrib - Contains demos scenarios for Heat, Magnum and Tacker and a development environment for Vagrant
  • doc - Contains documentation.
  • etc - Contains a reference etc directory structure which requires configuration of a small number of configuration variables to achieve a working All-in-One (AIO) deployment.
  • kolla_ansible - Contains password generation script.
