TripleO to deploy Ceph standlone

Here is a nice Christmas present: you can use TripleO for a standalone Ceph deployment, with just a few lines of YAML. Assuming you have an undercloud ready for a new overcloud, create an environment file like the following:

resource_registry:
  OS::TripleO::Services::CephMon: /usr/share/openstack-tripleo-heat-templates/puppet/services/ceph-mon.yaml
  OS::TripleO::Services::CephOSD: /usr/share/openstack-tripleo-heat-templates/puppet/services/ceph-osd.yaml

parameters:
  ControllerServices:
    - OS::TripleO::Services::CephMon
  CephStorageServices:
    - OS::TripleO::Services::CephOSD

and launch …


Ceph, TripleO and the Newton release

Time to roll up some notes on the status of Ceph in TripleO. The majority of these functionalities were available in the Mitaka release too but the examples work with code from the Newton release so they might not apply identical to Mitaka.

The TripleO default configuration

No default is going to fit everybody, but we want to know what the default is to improve from there. So let's try and see:

uc$ openstack overcloud …

OpenStack summit in Tokyo and TripleO

OpenStack summit Tokyo anyone? I've been there and thought it was a very well organized event, in a nice location. Every minute together with peers seemed worth it to me. This said, let's talk about the actual sessions. I spent most of my time at the TripleO and Heat sessions, with a little detour on Magnum. Plus some booth crawling.

TripleO

We had three sessions and a full day meetup. The first discussed the recent …


On TripleO and the EnablePacemaker bool

Yes, EnablePacemaker! A little old fashioned and not very well suited for OpenStack you say heh? Let's try to talk a bit about this then. News is that we're adding into TripleO/Puppet an option to deploy Pacemaker on the Overcloud nodes. Puppet you said? Sure TripleO can use Puppet now for the configuration of the Overcloud nodes, ask Dan Prince :) Actually usage of Puppet is nowdays the preferred approach and many features are available …


Ceph for Cinder in TripleO

A wrap up on the status of TripleO's Cinder HA spec. First, a link to the cinder-ha blueprint, where you can find even more links, to the actual spec (under review) and the code changes (again, still under review). Intent of the blueprint is for the TripleO deployments to keep Cinder volumes available and Cinder operational in case of failures of any node.

This said, should $subject sound interesting to you, beware the code still …
