TODO: move this to a centralized place Since the "Unhealthy" is a very universal event reason string, which could apply to all the TiDB/DM cluster components, we should make a global event module, and put event related constants there.

type OrphanPodsCleaner added in v1.0.0 

type OrphanPodsCleaner interface {
	Clean(metav1.Object) (map[string]string, error)
}

OrphanPodsCleaner implements the logic for cleaning the orphan pods(has no pvc)

In scaling out and failover, we will try to delete the old PVC to prevent it from being used by the new pod. However, the PVC might not be deleted immediately in the apiserver because of finalizers (e.g. kubernetes.io/pvc-protection) and the statefulset controller may not have received PVC delete event when it tries to create the new replica and the new pod will be pending forever because no PVC to use. We need to clean these orphan pods and let the statefulset controller to create PVC(s) for them.

https://github.com/kubernetes/kubernetes/blob/84fe3db5cf58bf0fc8ff792b885465ceaf70a435/pkg/controller/statefulset/stateful_pod_control.go#L175-L199

type PVCResizerInterface added in v1.1.4 

type PVCResizerInterface interface {
	Sync(*v1alpha1.TidbCluster) error
	SyncDM(*v1alpha1.DMCluster) error
}

PVCResizerInterface represents the interface of PVC Resizer. It patches the PVCs owned by tidb cluster according to the latest storage request specified by the user. See https://github.com/pingcap/tidb-operator/issues/3004 for more details.

Implementation:

for every unmatched PVC (desiredCapacity != actualCapacity) 

if storageClass does not support VolumeExpansion, skip and continue
if not patched, patch

We patch all PVCs of one Pod at the same time. For many cloud storage plugins (e.g. AWS-EBS, GCE-PD), they support online file system expansion in latest Kubernetes (1.15+).

Limitations:

  • Note that the current statfulset implementation does not allow `volumeClaimTemplates` to be changed, so new PVCs created by statefulset controller will use the old storage request.
  • This is best effort, before statefulset volume resize feature (e.g. https://github.com/kubernetes/enhancements/pull/1848) to be implemented.
  • If the feature `ExpandInUsePersistentVolumes` is not enabled or the volume plugin does not support, the pod referencing the volume must be deleted and recreated after the `FileSystemResizePending` condition becomes true.
  • Shrinking volumes is not supported.
