Guide de l'administrateur NetBackup™ pour Kubernetes

To create an API key

1. Open the NetBackup web UI.
2. On the left, click Security > Access keys.
3. Click the API keys tab.
4. Click Add.
5. On the Kubernetes cluster, create a new secret, nb-config-deploy-secret.yaml, with the following content.

   apiVersion: v1
   kind: Secret
   metadata:
     name: <kops-namespace>-nb-config-deploy-secret
     namespace: <kops-namespace>
   type: Opaque
   stringData:
     apikey: <Enter the value of API key from the earlier step>

6. Apply the secret. Run the command kubectl apply -f nb-config-deploy-secret.yaml.

Preinstallation

1. Edit the following fields in netbackupkops-helm-chart/values.yaml.

   • containers.manager.image: Container registry URL for pulling the NetBackup Kubernetes controller image.

   • imagePullSecrets name: name of the image pull secret if the container registry requires authentication to pull images.

   • nbprimaryserver: Configured name of NetBackup primary server.

   • nbsha256fingerprint: Fetch sha256 fingerprint from the NetBackup web UI. On the left click Security > Certificates. Click Certificate Authority.

   • k8sCluster: FQDN for Kubernetes cluster API server.

   • k8sPort: Port on which the Kubernetes API server is listed.

   • datamoverProperties (optional): Include any configuration settings that need to be specified in the datamover pod's bp.conf file.

     Remarque :

     For more information, Se reporter à Dépannage des serveurs NetBackup avec des noms courts.

   The information is available on the UI console of the Kubernetes cluster.

2. If it is not present, run the following command to get Kubernetes cluster and Kubernetes port:

   # kubectl cluster-info Kubernetes control plane runs at https://<Kubernetes FQDN>:6443

   • datamoverimage: Container registry URL to pull data mover image.

   • Storage parameters are required for snapshot and backup from snapshot operations. At least one of the Block or Filesystem storage parameters are mandatory.

3. To get the storage classes, run the following command:

   # kubectl get storageclasses

   • storageclassblock: Storage class that is used for provisioning block volumes.

   • storageclassfilesystem: Storage class that is used for provisioning file system volumes.

4. To get the volume snapshot class, run the following command:

   # kubectl get volumesnapshotclasses

   • volumesnapshotclassblock: Volume snapshot class for creating block volume snapshots.

   • volumesnapshotclassfilesystem: Volume snapshot class for creating file system volume snapshots.

5. Mapping between the storageclass and the snapshot class is managed through the storageMap. If a new storage option is added to the cluster, it can also be updated in the configmap for backup-operator-configuration after installation.

   • storageMap is a dictionary of key, value fields where key is storage class and its value is a tuple consisting of (snapshotClass, storageClassForBackupDataMovement, storageClassForRestoreFromBackup) This field is mandatory to specify mapping between storage class and snapshot class.

   • snapshotclass must be created with same provisioner as storage class and it must be capable of snapshotting the storage class. All storage classes should have their entry for snapshotclass.

   • storageClassForBackupDataMovement is used for creating temporary PVC for datamover. It must be compatible with original storage class PVC created using snapshot of original storage class must be readable when created using this storage class. Datamover reads data from this PVC and sends it to NetBackup media server. storageClassForRestoreFromBackup is used to restore from media server backup. It must be compatible with original storage class and come from same provisioner.

   • One snapshot class can be used for snapshotting multiple compatible storage classes.

   • Template

     storageMap:
       <key - storage class name>:
         snapshotClass: [mandatory field to specify volumesnapshotclass for creating snapshot of given key storage class]
         storageClassForBackupDataMovement: <optional, storage class used to transfer pvc backup data from k8s cluster to 
     NetBacup media server>
         storageClassForRestoreFromBackup: <optional, storage class used to restore pvc from NetBackup media server 
     to k8s cluster>
     
     Note: storageClassForBackupDataMovement and storageClassForRestoreFromBackup are optional and must be compatible 
     with key storage class if they are configured different from key storage class. If no value is specified for these 
     fields original 
     storage class would be used. These values can be changed later in backup-operator-configuration configmap
     
     Example for openshift storage classes. cephfs storage class should have corresponding snapclass as cephfs as follows
     storageMap:
       ocs-storagecluster-cephfs:
         storageClassForBackupDataMovement: ocs-storagecluster-cephfs
         storageClassForRestoreFromBackup: ocs-storagecluster-cephfs
         snapshotClass: ocs-storagecluster-cephfsplugin-snapclass
       ocs-storagecluster-ceph-rbd:
         snapshotClass: ocs-storagecluster-rbdplugin-snapclass
