This patch implements the Swift ring distribution and rebalance using an Ansible playbook, callable by a Mistral workflow. This has several benefits that are important for Swift clusters: - Rebalancing and ring deployment is possible without executing a full overcloud update. This is especially important when there is a longer rebalance in progress and/or multiple rebalances are required - Rebalancing can be scheduled using Mistral, for example to rebalance daily in a cron-like fashion - Avoids rebalances on every node, which is risky in case one or more nodes fail to rebalance and leave the cluster in an inconsistent state. - Rebalance only if it is safe, eg. a full replication run has finished after the last ring update The Ansible playbook can be executed either directly using ansible-playbook & tripleo-ansible-inventory, or by executing the Mistral workflow.

tripleo-common
A common library for TripleO workflows.

Action Development
When developing new actions, you will checkout a copy of tripleo-common to an undercloud machine and add actions as needed. To test the actions they need to be installed and selected services need to be restarted. Use the following code to accomplish these tasks. :
sudo rm -Rf /usr/lib/python2.7/site-packages/tripleo_common*
sudo python setup.py install
sudo cp /usr/share/tripleo-common/sudoers /etc/sudoers.d/tripleo-common
sudo systemctl restart openstack-mistral-executor
sudo systemctl restart openstack-mistral-engine
# this loads the actions via entrypoints
sudo mistral-db-manage populate
# make sure the new actions got loaded
mistral action-list | grep tripleoValidations
Prerequisites
If you haven't installed the undercloud with the
enable_validations set to true, you will have to prepare
your undercloud to run the validations:
$ sudo pip install git+https://git.openstack.org/openstack/tripleo-validations
$ sudo yum install ansible
$ sudo useradd validationsFinally you need to generate an SSH keypair for the validation user and copy it to the overcloud's authorized_keys files:
$ mistral execution-create tripleo.validations.v1.copy_ssh_keyRunning validations using the mistral workflow
Create a context.json file containing the arguments passed to the workflow:
{
"validation_names": ["512e", "rabbitmq-limits"]
}Run the tripleo.validations.v1.run_validations workflow
with mistral client:
mistral execution-create tripleo.validations.v1.run_validations context.jsonRunning groups of validations
Create a context.json file containing the arguments passed to the workflow:
{
"group_names": ["network", "post-deployment"]
}Run the tripleo.validations.v1.run_groups workflow with
mistral client:
mistral execution-create tripleo.validations.v1.run_groups context.json
