DigitalOcean Kubernetes (DOKS) is a managed Kubernetes service that lets you deploy Kubernetes clusters without the complexities of handling the control plane and containerized infrastructure. Clusters are compatible with standard Kubernetes toolchains, integrate natively with DigitalOcean Load Balancers and volumes, and can be managed programmatically using the API and command line. For critical workloads, add the high-availability control plane to increase uptime with 99.95% SLA.
In Kubernetes, a volume snapshot is a point-in-time copy of the contents of a Kubernetes cluster. You can use snapshots to back up a cluster’s data or copy the data to another resource without needing to create a new volume.
To import an existing snapshot into DigitalOcean as a volume, you need to create a new PVC that refers to the snapshot by calling kubectl create -f your_restore_file.yaml. Here’s an example of a YAML file that restores from a snapshot and creates a new PVC for use in the cluster:
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: csi-do-test-pvc-restore
spec:
dataSource:
name: csi-do-test-snapshot
kind: VolumeSnapshot
apiGroup: snapshot.storage.k8s.io
