Bug 1690468

Description of problem:

This looks like another occurrence of an OSP-12 bug that was allegedly fixed in bug #1488905.  A user is trying to upgrade their OSP-12 cloud to OSP-13 following these access.redhat.com guides:

https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/13/html/upgrading_red_hat_openstack_platform/

https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/12/html/upgrading_red_hat_openstack_platform/keeping_openstack_platform_updated#keeping_the_undercloud_updated

The user has the latest OSP-12 bits.  First they update their undercloud, then attempt a minor overcloud update.  This is the error they see:


$ openstack overcloud update stack --init-minor-update \
  --container-registry-file /home/stack/templates/overcloud_images.yaml
 
Stack overcloud UPDATE_FAILED

overcloud.AllNodesDeploySteps.WorkflowTasks_Step2_Execution:
  resource_type: OS::Mistral::ExternalResource
  physical_resource_id: dbc5309f-045e-4446-adde-5c152b53efab
  status: UPDATE_FAILED
  status_reason: |

    StackValidationFailed: resources.WorkflowTasks_Step2_Execution: Property error: Properties.actions.CREATE.workflow: Error validating value 'tripleo.overcloud.workflow_tasks.step2': The Workflow (tripleo.overcloud.workflow_tasks.step2) could not be found.
Heat Stack update failed.

It was suggested that he try re-running "openstack undercloud install" to regenerate the missing Mistral workflows, but this did not help.

openstack-tripleo-common-containers.noarch 7.6.13-6.el7ost 


How reproducible:

Unknown.  User has not been able to tear down environment and try from scratch as described below, due to operational constraints.


Steps to Reproduce:

1. Install new OSP-12 undercloud and deploy an overcloud
2. Follow OSP-12-to-13 upgrade guide
3. Run "openstack overcloud update stack --init-minor-update --container-registry-file /home/stack/templates/overcloud_images.yaml" and see error


Actual results:

Overcloud stack update failed.


Expected results:

Undercloud and overcloud updated to OSP-13.
