Multi-region scenario test¶
https://blueprints.launchpad.net/heat/+spec/multi-region-test
Add a scenario test for Multi-Region Orchestration.
Problem description¶
Heat supports Multi-Region Orchestration through remote stacks. While remote stacks themselves are tested with unit and functional tests, there are no scenario tests which test the creation of remote stacks across multiple regions.
Proposed change¶
This change will add a scenario test which creates two remote stacks in different regions and checks if their creation was successful.
This will require a multinode test setup with two distinct devstack instances, each configured with its own region. Multinode test setups are already possible in infra, but the configuration of regions requires changes to devstack-gate and openstack-infra/project-config to allow this test to run as a gate test.
Alternatives¶
In case it turns out to be impossible to create a multinode test setup with multiple regions in the openstack infrastructure, this scenario test could also be added as a local-only test which is not ran at the gate.

Work Items¶
Implement scenario test which does the following:
Create a stack containing two simple remote stacks
Both remote stacks target different regions
After sucessful creation, the output of the remote stacks is checked
Include scenario test in devstack-gate
Configure devstack multinode setup in project-config
Assign regions to the devstack nodes
Dependencies¶
