Summary

  • Replace the dual upstream model (QE fork vs validatedpatterns/ramendr-starter-kit v1.3) with a single elsapassaro/ramendr-starter-kit pin for all install variants (odf, drpartner-s4, drpartner-minimal).
  • Default PATTERN_VARIANT to odf and drop the unset “QE mixed-fleet fork” code path; variant selection always goes through main.variant.
  • Centralize upstream defaults in scripts/lib/pattern-variant.sh (UPSTREAM_REF131b3f0c93af6d3c75e3ce2f3bdd52455d24726c on ocp-4.22-rhdr-ramen); redeploy.sh sources that helper instead of hardcoding SHAs.
  • Patch partner variant values at install time with apply_rhdr_catalog() so hub/spoke subscriptions use the RHDR catalog (ramen-catalog, rhdr-multicluster-operator, rhdr-cluster-operator).
  • Relax GitOps variant enforcement for partner deploys: warn when fork main.variant lags local selection instead of failing redeploy (still required for odf).
  • Update smoke-test skip helpers and unit tests to treat odf as the default mixed-fleet variant; refresh README / CLAUDE / AGENT-HANDOFF.

Test plan

  • ./scripts/redeploy.sh --help shows PATTERN_VARIANT default odf and fork pin from pattern-variant.sh
  • PATTERN_VARIANT=odf ./scripts/redeploy.sh --pattern-only (or full redeploy) checks out fork @ 131b3f0… and patches main.variant: odf
  • PATTERN_VARIANT=drpartner-s4 ./scripts/redeploy.sh --pattern-only applies RHDR catalog patches under variants/drpartner-s4/ without failing on GitOps main.variant drift
  • pytest tests/utils/test_pattern_variant.py tests/utils/test_pattern_variant_yaml.py
  • Smoke tests still skip Windows/ODF assertions correctly for partner variants

Replace the dual upstream model (QE fork vs validatedpatterns v1.3) with
one elsapassaro/ramendr-starter-kit pin for all install variants. Default
PATTERN_VARIANT to odf, apply RHDR catalog subscriptions locally for partner
BOMs at install time, and warn when hub GitOps main.variant lags a local
partner selection instead of failing the redeploy.

  • Documentation

    • Updated deployment, GitOps, variant, and smoke-test guidance.
    • Documented fork-based deployments and pinned revisions.
  • Bug Fixes

    • Improved variant validation and configuration handling.
    • Ensured cleanup and required catalog updates run consistently during redeployment.

Walkthrough

The PR standardizes deployments on three fork-based variants, defaults unset selections to odf, adds RHDR catalog YAML patching, updates BYOC installation orchestration, and aligns redeploy documentation and tests.

Changes

Variant Deployment

Layer / File(s) Summary
Variant model and deployment contract
scripts/lib/pattern-variant.sh, tests/utils/*, AGENT-HANDOFF.md, CLAUDE.md, README.md
The supported variants are odf, drpartner-s4, and drpartner-minimal, with odf as the default. Variant capabilities, upstream pins, GitOps rules, deployment documentation, and tests were updated.
RHDR catalog transformation
scripts/lib/pattern_variant_yaml.py, tests/utils/test_pattern_variant_yaml.py
The YAML helper applies RHDR index images and hub or spoke subscriptions. The rhdr CLI command and partner YAML tests were added.
BYOC bootstrap and install monitoring
scripts/lib/byoc-import-wait.sh, tests/utils/test_pattern_install_wait.py
BYOC spoke secrets are bootstrapped locally. Installation health and joined-spoke progress are monitored, with early exit and ODF application nudging support.
Redeploy integration
scripts/redeploy.sh
Redeploy resolves the selected variant centrally, applies variant and RHDR patches, performs unconditional legacy cleanup, integrates BYOC monitoring, and reports the resolved main.variant configuration.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to ed920

The installer can proceed with an incomplete deployment, terminate after non-consecutive healthy checks, or generate partner configuration with an obsolete subscription key. These issues can cause failed or incompatible deployments, so the PR is not merge-ready until they are fixed.

335-357: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Do not retire the active GitOps application before install success.

deploy_pattern calls these functions at Lines 880-881 before it evaluates pattern_exit at Line 883. The removed variant gates now make this cleanup run for default ODF deployments too.

If pattern.sh make install-byoc fails before it creates the selected application, retire_previous_clustergroup_apps can delete the active prior parent application. The environment then has no confirmed replacement reconciliation source.

Run this cleanup only after a successful or explicitly recoverable install and after the selected application exists.

Bootstrap spoke hub namespaces and import secrets during install-byoc so
odf-dr/opp-policy jobs can progress before regional-dr exists, restore the
pre-PR-#25 OR recoverability gate, and cut the 60-minute health loop early
when only known drift or pending spoke import remains. Consolidate the logic
into byoc-import-wait.sh and add recoverability unit tests.

66-75: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Replace the obsolete hub subscription entry.

Lines 73-75 keep odf-multicluster-orchestrator as the map key. The RHDR configuration must use rhdr-multicluster-operator as the key and remove the obsolete ODF entry. Otherwise the generated hub values do not match the new RHDR contract or its test.

Proposed fix
     subscriptions = cluster_group.setdefault("subscriptions", {})
-    if subscriptions.get("odf-multicluster-orchestrator") != RHDR_HUB_MCO_SUBSCRIPTION:
-        subscriptions["odf-multicluster-orchestrator"] = dict(RHDR_HUB_MCO_SUBSCRIPTION)
+    if subscriptions.pop("odf-multicluster-orchestrator", None) is not None:
+        changed = True
+    if subscriptions.get("rhdr-multicluster-operator") != RHDR_HUB_MCO_SUBSCRIPTION:
+        subscriptions["rhdr-multicluster-operator"] = dict(RHDR_HUB_MCO_SUBSCRIPTION)
         changed = True

We keep the subscription map key as odf-multicluster-orchestrator to match the fork’s values layout (variants/odf/values-odf.yaml and partner variants). The RHDR patch updates the subscription name to rhdr-multicluster-operator and source to ramen-catalog; that’s what test_apply_rhdr_catalog_patches_partner_hub_and_spoke asserts.
