Previously in python-tripleoclient, they tried to use UpdateIdentifier or two different things: tell whether to perform package update, and also to tell whether the top-level stack is being created or updated (which was incorrect and resulted in bug 1567384, and an attempt to work around that bug resulted in bug 1567385). Heat's "action" conditionals cannot be used in some cases, because they refer to the direct parent stack, which can yield undesirable results when introducing new nested stacks or temporarily no-opping something and then adding it back (in both these cases, "action" would be considered "CREATE", even though the top-level stack is in "UPDATE"). UpdateIdentifier is cleared on deploy/scale to make sure that package update doesn't get triggered, and we pass the StackAction parameter to allow us to correctly distinguish between create vs. update of the top-level stack, and condition the pacemaker restarts on this variable instead. This patch sets the parameters mentioned above and stores them in a Mistral Environment. These parameters are retrieved during the ProcessTemplatesAction and subsequently merged into the Heat environment. Change-Id: I22a42038a265ca7d4ab309412935df5d7370f1b3

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 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_key
