villebro opened a new pull request, #24:
URL: https://github.com/apache/superset-kubernetes-operator/pull/24
## Summary
Replaces the single `SupersetInit` CRD and `spec.init` field with a
general-purpose `SupersetTask` CRD and `spec.lifecycle` field that splits
database migration and application initialization into two sequential,
independently-configurable tasks.
This is the foundation for intelligent upgrade lifecycle management — a
significant differentiator over the Helm chart, which has no concept of
database-migration-aware deployment orchestration.
## Key changes
- Two-task split: `superset db upgrade` (migrate) and `superset init` (init)
run as separate `SupersetTask` CRs (`{parent}-migrate`, `{parent}-init`), each
with independent retry/timeout
- Image-change detection: tasks only run when the image actually changes
(`VersionChange` strategy). Config-only changes trigger rolling restart via pod
annotations — no task pods needed
- Downgrade blocking: semver comparison detects downgrades and blocks with a
clear error (Alembic migrations are forward-only)
- Supervised mode: `upgradeMode: Supervised` pauses the lifecycle until the
user approves via annotation
- Task strategies: `VersionChange` (default), `Always`, `Never` — per-task
control over when each runs
- Extensible design: `SupersetTask` CRD is generic enough for future task
types (probes, hooks, staging) without breaking changes
### Breaking changes
- `spec.init` → `spec.lifecycle` (field rename + restructure)
- `SupersetInit` CRD → SupersetTask CRD (kind rename)
- Config-only changes no longer trigger task pods
- `status.init` → `status.lifecycle`
### Test plan
- `go test ./...` passes (unit + integration)
- make lint — 0 issues
- make codegen — all generated artifacts up to date
- Version comparison: upgrade, downgrade, rebuild, unknown, v-prefix,
pre-release, SHA tags
- Lifecycle gating: components don't deploy until tasks complete
- Strategy=Never: task CR not created
- Supervised mode: blocks until approval annotation
- Downgrade: blocks with condition + event
- E2E with Kind cluster (manual)
