Description
Description of problem:
Currrently, only one ServerGroup is created in OpenStack when 3 masters on 3 AZs are deployed while 3 should have been created (one per AZ). With the work on CPMS, we made the decision to only create one ServerGroup for the masters. However, this will require a change in the installer to reflect this decision. Indeed, when specifying AZs, the master machines would have their own ServerGroup, while only one actually existed in OpenStack. This was a mistake but instead of fixing that bug, we'll change the behaviour to have only one ServerGroup for masters.
Version-Release number of selected component (if applicable):
latest (4.14)
How reproducible: deploy a control plane with 3 failure domains:
controlPlane: name: master platform: openstack: type: m1.xlarge failureDomains: - computeAvailabilityZone: az0 - computeAvailabilityZone: az1 - computeAvailabilityZone: az2
Steps to Reproduce:
1. Deploy the control plane in 3 AZ 2. List OpenStack Compute Server Groups
Actual results:
+--------------------------------------+--------------------------+--------------------+ | ID | Name | Policy | +--------------------------------------+--------------------------+--------------------+ | 0750c579-d2cf-41b3-9e88-003dcbcad0c5 | refarch-jkn8g-master-az0 | soft-anti-affinity | | 05715c08-ac2b-439d-9bd5-5803ac40c322 | refarch-jkn8g-worker | soft-anti-affinity | +--------------------------------------+--------------------------+--------------------+
Expected results without our work on CPMS:
refarch-jkn8g-master-az1 and refarch-jkn8g-master-az2 should have been created.
This expectation is purely for documentation, QE should ignore it.
Expected results with our work on CPMS (which should be taken in account by QE when testing CPMS):
refarch-jkn8g-master-az0 should not exist, and the ServerGroup should be named refarch-jkn8g-master. All the masters should use that ServerGroup in both the Nova instance properties and in the MachineSpec once the machines are enrolled by CCPMSO.
