tripleo-common

A common library for TripleO workflows.

Free software: Apache license
Documentation: https://docs.openstack.org/tripleo-common/latest/

Bugs: https://bugs.launchpad.net/tripleo-common
Release notes: https://docs.openstack.org/releasenotes/tripleo-common

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 tripleo

Workflow Development

When developing new workflows, you will need to reload the modified workflows, e.g the following will reload all the workflows from the default packaged location, or you can use a similar approach to replace only a single workbook while under development. :

for workbook in $(openstack workbook list -f value -c Name | grep tripleo); do
    openstack workbook delete $workbook
done
for workflow in $(openstack workflow list -f value -c Name | grep tripleo); do
    openstack workflow delete $workflow
done
for workbook in $(ls /usr/share/openstack-tripleo-common/workbooks/*); do
    openstack workbook create $workbook
done

Validations

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 validations

Finally 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_key

Running 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.json

Running groups of validations
