# cc-ci overlay (Phase 2 Q4.6) — minimal, single-purpose: make the UPGRADE-tier BASE deploy (the
# previous published discourse version) deployable so upgrade-to-latest can run.
#
# WHY THIS OVERLAY EXISTS (plan-ccci-compose-overlay-policy.md §1 "minimal justified fallback" +
# the §1 mandate that upgrade-to-latest must ALWAYS run): the harness base-deploys the from-version
# (UPGRADE_BASE_VERSION = 0.7.0+3.3.1), then `deploy --chaos` to the recipe-PR head. Two blockers on
# that published base, both resolved here, NEITHER weakening any test:
#   1. RE-PIN: every published discourse tag pins `bitnami/discourse:3.3.1` (and 0.6.3 → 3.1.2),
#      but Docker Hub REMOVED the bitnami/discourse namespace (404). The recipe-PR (recipe-maintainers/
#      discourse#1) re-pins app+sidekiq to `bitnamilegacy/discourse:3.3.1` (the legit upstream
#      relocation of the identical image). This overlay applies the SAME namespace-only re-pin to the
#      BASE 0.7.0 (identical version 3.3.1, identical image content) so the from-version pulls — exactly
#      the policy-blessed "minimal bitnami→bitnamilegacy re-pin overlay on the 0.7.0 from-version".
#   2. GRACE: discourse's Rails cold first boot (DB migrate + asset precompile) is 15-25min on cc-ci,
#      exceeding the published 5m start_period → swarm kills the still-booting app. start_period CANNOT
#      be an env var (abra validates the literal 'duration' BEFORE substitution → FATA; Adversary-
#      reproduced, REVIEW-2 4b862f6), so we widen it to a literal 20m on the BASE. The PR head already
#      ships 20m, so this overlay is idempotent on the head (it persists untracked across the checkout).
# Both changes are namespace/grace-only: identical image content, a healthy check still marks healthy
# immediately → NO assertion is weakened and no defect is masked.
#
# NOTE (prepull): the published recipe ships `sidekiq.depends_on: [discourse]` but the main service is
# named `app` (`discourse` is undefined), so `abra app config --images` returns invalid-compose (rc=15)
# and the harness prepull is SKIPPED. This overlay does NOT try to override depends_on — compose
# normalizes short-form depends_on to a map and map-merge is additive, so an override can't REMOVE the
# bad `discourse` key. Instead the 2.4GB `bitnamilegacy/discourse:3.3.1` image is kept warm in the node
# image cache, so the inline pull during deploy is a no-op and convergence isn't pull-bound. (swarm
# ignores depends_on, so the dangling ref has zero runtime effect — a recipe lint nit, not a defect.)
