Manage kubernetes StatefulSet
Operations
Increase the storage sizes without downtime
We cannot update the resources.storageSize of the StatefulSet to increase the volume sizes. So, we have to follow a few steps to update them.
See this article for more details.
- Confirm if the storageclass of persistent volumes has
.allowVolumeExpansion=true> kubectl get storageclass standard -o yaml | yq .allowVolumeExpansion true - Update all PVC to have more storage sizes
- Delete the statefulset objects without deleting pods by
kubectl delete statefulset $statefulset_name --cascade=orphan - Recreate the statefulset with the new storage size
Decrease the storage size
Shrinking disk sizes is not supported. official document.
