Documentation for version v1.0.0 is no longer actively maintained. The version you are currently viewing is a static snapshot. For up-to-date documentation, see the latest version.
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.
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:
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.
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.
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.
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
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.
After you set up the Velero server, try these examples:
Start the sample nginx app:
kubectl apply -f examples/nginx-app/base.yaml
Create a backup:
velero backup create nginx-backup --include-namespaces nginx-example
Simulate a disaster:
kubectl delete namespaces nginx-example
Wait for the namespace to be deleted.
Restore your lost resources:
velero restore create --from-backup nginx-backup
NOTE: For Azure, you must run Kubernetes version 1.7.2 or later to support PV snapshotting of managed disks.
Start the sample nginx app:
kubectl apply -f examples/nginx-app/with-pv.yaml
Create a backup with PV snapshotting:
velero backup create nginx-backup --include-namespaces nginx-example
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.
Restore your lost resources:
velero restore create --from-backup nginx-backup
