A pacemaker bundle can be restarted either because:
. a tripleo config has been updated (from /var/lib/config-data)
. the bundle config has been updated (container image, bundle
parameter,...)
In HA services, special container "*_restart_bundle" is in charge
of restarting the HA service on tripleo config change. Special
container "*_init_bundle" handles restart on bundle config change.
When both types of change occur at the same time, the bundle must
be restarted first, so that the container has a chance to be
recreated with all bind-mounts updated before it tries to reload
the updated config.
Implement the improvement with two changes:
1. Make the "*_restart_bundle" start after the "*_init_bundle", and
make sure "*_restart_bundle" is only enabled after the initial
deployment.
2. During minor update, make sure that the "*_restart_bundle" not
only restarts the container, but also waits until the service
is operational (e.g. galera fully promoted to Master). This forces
the rolling restart to happen sequentially, and avoid service
disruption in quorum-based clustered services like galera and
rabbitmq.
Tested the following update use cases:
* minor update: ensure that *_restart_bundle restarts all types of
resources (OCF, bundles, A/P, A/P Master/Slave).
* minor update: ensure *_restart_bundle is not executed when no
config or image update happened for a service.
* restart_bundle: when resource (OCF or container) fails to
restart, bail out early instead of waiting for nothing until
timeout is reached.
* restart_bundle: make sure a resource is restarted even when it
is in failed stated when *_restart_bundle is called.
* restart_bundle: A/P can be restarted on any node, so watch
restart globally. When the resource restarts as Slave, continue
watching for a Master elsewhere in the cluster.
* restart_bundle: if an A/P is not running locally, make sure it
doesn't get restarted anywhere else in the cluster.
* restart_bundle: do not try to restart stopped (disabled) or
unmanaged resource. Bail out early instead, to not wait until
timeout is reached.
* stack update: make sure that running a stack update with no
change does not trigger any *_restart_bundle, and does not
restart any HA container either.
* stack update: when bundle and config will change, ensure bundle
is updated before HA containers are restarted (e.g. HAProxy
migration to TLS everywhere)

tripleo-heat-templates
Heat templates to deploy OpenStack using OpenStack.
- Free software: Apache License (2.0)
- Documentation: https://docs.openstack.org/tripleo-docs/latest/
- Source: https://opendev.org/openstack/tripleo-heat-templates
- Bugs: https://bugs.launchpad.net/tripleo
- Release notes: https://docs.openstack.org/releasenotes/tripleo-heat-templates/
Features
The ability to deploy a multi-node, role based OpenStack deployment using OpenStack Heat. Notable features include:
- Choice of deployment/configuration tooling: puppet, (soon) docker
- Role based deployment: roles for the controller, compute, ceph, swift, and cinder storage
- physical network configuration: support for isolated networks, bonding, and standard ctlplane networking
Directories
A description of the directory layout in TripleO Heat Templates.
- environments: contains heat environment files that can be used with -e
on the command like to enable features, etc.
- extraconfig: templates used to enable 'extra' functionality. Includes
functionality for distro specific registration and upgrades.
- firstboot: example first_boot scripts that can be used when initially
creating instances.
- network: heat templates to help create isolated networks and ports
- puppet: templates mostly driven by configuration with puppet. To use these
templates you can use the overcloud-resource-registry-puppet.yaml.
- validation-scripts: validation scripts useful to all deployment
configurations
- roles: example roles that can be used with the tripleoclient to generate
a roles_data.yaml for a deployment See the roles/README.rst for additional details.
Service testing matrix
The configuration for the CI scenarios will be defined in tripleo-heat-templates/ci/ and should be executed according to the following table:
| - | scn000 | scn001 | scn002 | scn003 | scn004 | scn006 | scn007 | scn009 | scn010 | non-ha | ovh-ha |
