DataExport

Subcommand for the command line client for Deckhouse.

The export target is referenced by kind (targetRef.kind, the API group is derived from it). Supported target kinds and their CLI aliases:

Available Commands:

• create - Create k8s DataExport object.

Examples

create

d8 data create export-name pvc/test-pvc-name

create from a snapshot

1. Enable snapshot-controller module

kubectl apply -f -<<EOF
apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: snapshot-controller
spec:
  enabled: true
  version: 1
EOF

1. Get a volume snapshot class name - this entity is created automatically for each type of CSI and is needed for creating a snapshot. For example, "sds-local-volume-snapshot-class" as shown in the example below

kubectl get volumesnapshotclass

sds-local-volume-snapshot-class   local.csi.storage.deckhouse.io   Delete           22h

1. Create a snapshot of a needed volume

kubectl apply -f -<<EOF
apiVersion: snapshot.storage.k8s.io/v1
kind: VolumeSnapshot
metadata:
  name: my-snapshot
  namespace: <name of the namespace where the PVC is located>
spec:
  volumeSnapshotClassName: <volume snapshot class name>
  source:
    persistentVolumeClaimName: <name of the PVC to snapshot>
EOF

1. Check that snapshot is created normally and ready to use (usually takes a few minutes to be ready):

kubectl -n <name of the namespace> get volumesnapshot my-snapshot

NAMESPACE       NAME                  READYTOUSE   SOURCEPVC                        SOURCESNAPSHOTCONTENT   RESTORESIZE   SNAPSHOTCLASS                     SNAPSHOTCONTENT                                  
<namespace>    my-snapshot          true         test-pvc-for-snapshot                           2Gi           sds-local-volume-snapshot-class   snapcontent-faf2ab1f-891d-4e5e-972c-334a490c99d8

1. Create data export from that snapshot using d8 command as shown in the example below

d8 data create export-name vs/my-snapshot
