2017-03-13Tasks hook for preparing BM host for deploying containerized servicesJiri Stransky1-1/+27
This implements a host_prep_tasks hook where we can specify Ansible tasks to perform on the host before deploying containerized services. The hook runs in a single step, the assumption is that we will mostly use the hook for creating per-service directories on the host to ensure we are able to mount them into the containers. (We cannot do this operation via Puppet because all containerized services run their Puppet within a config container, so Puppet doesn't have access to host's filesystem.)

2017-03-10Remove docker_image sections (unused)Dan Prince1-6/+5
We don't use docker_image for anything. It is a remant of the pre-composable docker templates and we can now remove it. This patch removes references to the 'docker_image' section from docker/post.yaml and all of the docker/services* templates. Change-Id: I208c1ef1550ab39ab0ee47ab282f9b1937379810
2017-03-06Enable composable upgrades for docker service templatesSteven Hardy1-0/+325
This aligns the docker based services with the new composable upgrades architecture we landed for ocata, and does a first-pass adding upgrade_tasks for the services (these may change, atm we only disable the service on the host). To run the upgrade workflow you basically do two steps: openstack overcloud deploy --templates \ -e environments/major-upgrade-composable-steps-docker.yaml This will run the ansible upgrade steps we define via upgrade_tasks then run the normal docker PostDeploySteps to bring up the containers. For the puppet workflow there's then an operator driven step where compute nodes (and potentially storage nodes) are upgrades in batches and finally you do: openstack overcloud deploy --templates \ -e environments/major-upgrade-converge-docker.yaml In the puppet case this re-applies puppet to unpin the nova RPC API so I guess it'll restart the nova containers this affects but otherwise will be a no-op (we also disable the ansible steps at this point.
