Add a new pre-upgrade hook migration that walks every HelmRelease
spec.values and every app CR spec under apps.cozystack.io/v1alpha1, and
rewrites legacy flat resourcesPreset values (nano/micro/small/medium/
large/xlarge/2xlarge) to their instance-type equivalents (t1/c1).
Mapping is 1:1 by CPU and memory — the migration never bumps resource
usage. The same table lives in cozy-lib (legacy aliases) and in
pkg/apis/apps/presets/legacy.go.
Properties:
- Idempotent: re-running on a converted cluster is a no-op because
non-legacy values fall through the jq map_legacy else arm.
- Best-effort: a single failed patch logs a warning and continues;
cozy-lib legacy aliases keep charts rendering with identical CPU
and memory even if the migration is incomplete. kubectl patch
stderr is captured and surfaced in the WARN line so operators see
why a patch was rejected.
- Distinguishes "no items" from "kubectl errored" (RBAC stripped,
network down, CRD missing) so a broken cluster cannot look
identical to a clean no-op run and stamp the version
unconditionally.
- Dry-run: MIGRATION_DRY_RUN=1 prints the would-be patches and
leaves the version stamp at 39.
- Final summary echoed to both stdout and stderr.
- Version stamp only advances to 40 on a fully successful real run.
Bump migrations.targetVersion 39 -> 40 so the hook executes on the
next platform upgrade.
