Set up Velero on your platform

You can run Velero with a cloud provider or on-premises. For detailed information about the platforms that Velero supports, see Compatible Storage Providers.

You can run Velero in any namespace, which requires additional customization. See Run in custom namespace.

You can also use Velero’s integration with restic, which requires additional setup. See restic instructions.

Cloud provider

The Velero client includes an install command to specify the settings for each supported cloud provider. You can install Velero for the included cloud providers using the following command:

velero install \
    --provider <YOUR_PROVIDER> \
    --bucket <YOUR_BUCKET> \
    --secret-file <PATH_TO_FILE> \
    [--backup-location-config]
    [--snapshot-location-config]
    [--namespace]
    [--use-volume-snapshots]
    [--use-restic]

For provider-specific instructions, see:

• Run Velero on AWS
• Run Velero on GCP
• Run Velero on Azure
• Use IBM Cloud Object Store as Velero’s storage destination

When using restic on a storage provider that doesn’t currently have Velero support for snapshots, the --use-volume-snapshots=false flag prevents an unused VolumeSnapshotLocation from being created on installation.

To see the YAML applied by the velero install command, use the --dry-run -o yaml arguments.

For more complex installation needs, use either the generated YAML, or the Helm chart.

On-premises

You can run Velero in an on-premises cluster in different ways depending on your requirements.

First, you must select an object storage backend that Velero can use to store backup data. Compatible Storage Providers contains information on various options that are supported or have been reported to work by users. Minio is an option if you want to keep your backup data on-premises and you are not using another storage platform that offers an S3-compatible object storage API.

Second, if you need to back up persistent volume data, you must select a volume backup solution. Volume Snapshot Providers contains information on the supported options. For example, if you use Portworx for persistent storage, you can install their Velero plugin to get native Portworx snapshots as part of your Velero backups. If there is no native snapshot plugin available for your storage platform, you can use Velero’s restic integration, which provides a platform-agnostic backup solution for volume data.

Customize configuration

Whether you run Velero on a cloud provider or on-premises, if you have more than one volume snapshot location for a given volume provider, you can specify its default location for backups by setting a server flag in your Velero deployment YAML.

For details, see the documentation topics for individual cloud providers.

Removing Velero

If you would like to completely uninstall Velero from your cluster, the following commands will remove all resources created by velero install:

kubectl delete namespace/velero clusterrolebinding/velero
kubectl delete crds -l component=velero

Installing with the Helm chart

When installing using the Helm chart, the provider’s credential information will need to be appended into your values.

The easiest way to do this is with the --set-file argument, available in Helm 2.10 and higher.

helm install --set-file credentials.secretContents.cloud=./credentials-velero stable/velero

See your cloud provider’s documentation for the contents and creation of the credentials-velero file.

Examples

After you set up the Velero server, try these examples:

Basic example (without PersistentVolumes)

1. Start the sample nginx app:

   kubectl apply -f examples/nginx-app/base.yaml
   

2. Create a backup:

   velero backup create nginx-backup --include-namespaces nginx-example
   

3. Simulate a disaster:

   kubectl delete namespaces nginx-example
   

   Wait for the namespace to be deleted.

4. Restore your lost resources:

   velero restore create --from-backup nginx-backup
   

Snapshot example (with PersistentVolumes)

NOTE: For Azure, you must run Kubernetes version 1.7.2 or later to support PV snapshotting of managed disks.

1. Start the sample nginx app:

   kubectl apply -f examples/nginx-app/with-pv.yaml
   

2. Create a backup with PV snapshotting:

   velero backup create nginx-backup --include-namespaces nginx-example
   

3. Simulate a disaster:

   kubectl delete namespaces nginx-example
   

   Because the default reclaim policy for dynamically-provisioned PVs is “Delete”, these commands should trigger your cloud provider to delete the disk that backs the PV. Deletion is asynchronous, so this may take some time. Before continuing to the next step, check your cloud provider to confirm that the disk no longer exists.

4. Restore your lost resources:

   velero restore create --from-backup nginx-backup
