🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winAdd a test case that explicitly passes
event_persistence.database_secret: "".The sample CR leaves
event_persistence.database_secretabsent, so the test covers only the absent-field case. The guard conditionevent_persistence.database_secret | default('') | length > 0is designed to handle both the absent case and the explicitly empty-string case identically — both evaluate to false and permit auto-generation. The mirrored guard inset_event_persistence_secret.yml(line 12) applies the same check before attempting a lookup.If the guard logic were incorrectly changed — for example, to
when: event_persistence.database_secret is defined— a regression would be caught when an explicitly empty string is passed (because it is defined, so the lookup would attempt to use''as the secret name and fail), but the current test would not detect this because it does not exercise that code path. The test therefore does not verify that empty-string values are correctly treated as unset.Suggested fix

… guards
Replace the `is defined` guards on event_stream.database_secret and
event_persistence.database_secret with `| default('') | length > 0` so both
undefined and empty-string are treated as unset. This lets a VSO-pre-created
secret referenced on the CR be adopted and preserved on reconcile, while an
unset/empty field still auto-generates the default-named secret. Applied
across roles/postgres/tasks/main.yml, set_event_stream_secret.yml, and
set_event_persistence_secret.yml.
Add a molecule guard test that pre-creates a "VSO-managed" event stream secret
and asserts it is adopted (not regenerated) and that event persistence
auto-generates when no secret is provided. Extend the sample CR with
event_stream.database_secret and event_persistence.deploy_db to exercise both
branches.

Problem
event_stream.database_secretandevent_persistence.database_secreton an EDA CR are guarded withis definedchecks. Once an empty-string default is introduced for those fields — needed so aVSO-managed secret can be pre-created and adopted by the operator — the guards misfire: an unset
field defaults to
'', which is still "defined", so the operator treats it as a real secretreference instead of falling back to auto-generation. The external-database validation likewise can
no longer tell "not provided" from "provided empty".
Cause
The role mixed two different notions of "unset" and neither collapses the undefined and empty-string
cases into one:
event_stream.database_secret is defined and ... | length > 0— theis definedhalf is defeatedby an empty-string default, so
''reads as a set reference.event_stream.database_secret is not defined or not event_stream.database_secret— thefail-validation used yet another idiom for the same intent.
This is the same guard bug fixed in galaxy-operator #283.
Fix
Replace the guards with a single
| default('') | length > 0idiom across the postgres role so bothundefined and empty-string are treated as unset:
roles/postgres/tasks/main.yml— event stream / event persistence secret selection and theexternal-DB validation
roles/postgres/tasks/set_event_stream_secret.ymlroles/postgres/tasks/set_event_persistence_secret.ymlNet effect: a CR-referenced (VSO-pre-created) secret is adopted and preserved on reconcile, and when
the field is unset/empty the operator auto-generates the default-named secret exactly as before.
Testing
Added a molecule guard test (
molecule/default/tasks/postgres_secret_guard_test.yml) that:prepare.ymlwith a sentinel passwordis untouched, and no default-named secret is generated
deploy_db: true, nodatabase_secret) auto-generates anoperator-managed secret with a fresh, distinct password
| length > 0boolean cast and the adopt-vs-generate ternary logicAlso extended the sample CR (
config/samples/eda_v1alpha1_eda.yaml) withevent_stream.database_secretand
event_persistence.deploy_dbto exercise both branches.Ref: AAP-91811, ANSTRAT-2212
