| Type | Description |
|---|---|
| Kubernetes snapshot CRDs | IBM Cloud Kubernetes Service installs Kubernetes snapshot custom resource definition (CRD) version v1beta1. If you use other Kubernetes snapshot CRD versions v1 or v1alpha1, you must change the
version to v1beta1. To check the currently installed version of your snapshot CRDs, run grep snapshot.storage.k8s.io <<(kubectl get apiservices). Follow the Kubernetes documentation to Upgrade from v1alpha1 to v1beta1 to make sure that your snapshot CRDs are at the correct v1beta1 version. The steps to downgrade from version v1 to v1beta1 are the same as those to upgrade from v1alpha1. Do not follow the instructions to upgrade from version v1beta1 to version v1. |
