PVCs and CloudNativePG Clusters need S3 buckets and backup schedules
provisioned consistently. This operator watches the
backups.unkin.net/{schedule,destination} annotations on those objects and
provisions everything needed to back them up, with no new CRDs.
- Add a PVC controller that provisions cephrgw ObjectStoreUser/Bucket/BucketAccess,
auto-generates a restic repo-password Secret and creates a k8up Schedule scoped
to the PVC via spec.backup.volumes[].persistentVolumeClaim.claimName.
- Add a CNPG Cluster controller that provisions the same bucket stack, idempotently
patches spec.backup.barmanObjectStore (leaving a user-set destinationPath alone
with a Warning event) and creates a ScheduledBackup.
- Resolve destinations through a ConfigMap lookup table; requeue until the
BucketAccess is Ready before creating schedule resources; own-reference created
resources and retain bucket data by default.
- Add schedule-mapping helpers (k8up 5-field/shortcut pass-through, CNPG 6-field
seconds-first) and deterministic, length-bounded name derivation.
- Add unit tests (schedule mapping, name derivation, destination resolution) and
envtest controller tests for both paths, wiring the external CRDs into envtest.
- Add kubebuilder-generated RBAC, a Dockerfile (distroless/nonroot), Woodpecker
lint/test/build pipelines and a tag-triggered image push to the artifactapi
docker-internal registry, plus a version-bump Makefile and deploy manifests.

* concurrent.Map: backport sync.Map for go below 1.9
|
|
* concurrent.Executor: goroutine with explicit ownership and cancellable
|
|
|
|
# concurrent.Map
|
|
|
|
because sync.Map is only available in go 1.9, we can use concurrent.Map to make code portable
|
|
|
|
```go
|
|
m := concurrent.NewMap()
|
|
m.Store("hello", "world")
|
|
elem, found := m.Load("hello")
|
|
// elem will be "world"
|
|
// found will be true
|
|
```
|
|
|
|
# concurrent.Executor
|
|
|
|
```go
|
|
executor := concurrent.NewUnboundedExecutor()
|
|
executor.Go(func(ctx context.Context) {
|
|
everyMillisecond := time.NewTicker(time.Millisecond)
|
|
for {
|
|
select {
|
|
case <-ctx.Done():
|
|
fmt.Println("goroutine exited")
|
|
return
|
|
case <-everyMillisecond.C:
|
|
// do something
|
|
}
|
|
}
|
|
})
|
|
time.Sleep(time.Second)
|
|
executor.StopAndWaitForever()
|
|
fmt.Println("executor stopped")
|
|
```
|
|
|
|
attach goroutine to executor instance, so that we can
|
|
|
|
* cancel it by stop the executor with Stop/StopAndWait/StopAndWaitForever
|
|
* handle panic by callback: the default behavior will no longer crash your application |
