Velero

Velero is a backup, recovery, and migration tool for Kubernetes cluster objects, including persistent volumes. With Velero, you can:

• Protect your data from loss using a flexible backup system.
• Recover a cluster faster if it goes down.
• Move your data from one cluster to another.

Velero uses the Container Storage Interface driver to create backups and restore persistent volumes from Yandex Cloud disk snapshots.

1. Create a service account required to access Yandex Object Storage:

   yc iam service-account create --name <service account name>
   

2. Assign the storage.editor role to the service account:

   yc resource-manager folder add-access-binding <folder ID> \
      --role storage.editor \
      --subject serviceAccount:<service account ID>
   

3. Create a static access key for the service account in JSON format and save it to the sa-key.json file:

   yc iam access-key create \
      --service-account-name=<service account name> \
      --format=json > sa-key.json
   

4. Create an Object Storage bucket for storing backups.

5. Configure the application:

   • Namespace: Create a namespace called velero. The application uses it by default. If you select a different namespace, you will have to specify it in each command.
   • Application name: Enter a name for the application.
   • Object Storage static access key: Paste the contents of the sa-key.json file.
   • Object Storage bucket name: Specify the name of the bucket in Object Storage.

6. Click Install.

7. Wait for the application to change its status to Deployed.

• Creating backups for Kubernetes cluster resources and persistent volumes.
• Restoring cluster data from backups.
• Migrating data from one Kubernetes cluster to another.
