Run Velero on Azure

To configure Velero on Azure, you:

If you do not have the az Azure CLI 2.0 installed locally, follow the install guide to set it up.


az login

Kubernetes cluster prerequisites

Ensure that the VMs for your agent pool allow Managed Disks. If I/O performance is critical, consider using Premium Managed Disks, which are SSD backed.

Download Velero

  1. Download the latest official release’s tarball for your client platform.

    We strongly recommend that you use an official release of Velero. The tarballs for each release contain the velero command-line client. The code in the master branch of the Velero repository is under active development and is not guaranteed to be stable!

  2. Extract the tarball:
     tar -xvf <RELEASE-TARBALL-NAME>.tar.gz -C /dir/to/extract/to 

    We’ll refer to the directory you extracted to as the “Velero directory” in subsequent steps.

  3. Move the velero binary from the Velero directory to somewhere in your PATH.

Create Azure storage account and blob container

Velero requires a storage account and blob container in which to store backups.

The storage account can be created in the same Resource Group as your Kubernetes cluster or separated into its own Resource Group. The example below shows the storage account created in a separate Velero_Backups Resource Group.

The storage account needs to be created with a globally unique id since this is used for dns. In the sample script below, we’re generating a random name using uuidgen, but you can come up with this name however you’d like, following the Azure naming rules for storage accounts. The storage account is created with encryption at rest capabilities (Microsoft managed keys) and is configured to only allow access via https.

# Create a resource group for the backups storage account. Change the location as needed.
az group create -n $AZURE_BACKUP_RESOURCE_GROUP --location WestUS

# Create the storage account
AZURE_STORAGE_ACCOUNT_ID="velero$(uuidgen | cut -d '-' -f5 | tr '[A-Z]' '[a-z]')"
az storage account create \
    --resource-group $AZURE_BACKUP_RESOURCE_GROUP \
    --sku Standard_GRS \
    --encryption-services blob \
    --https-only true \
    --kind BlobStorage \
    --access-tier Hot

Create the blob container named velero. Feel free to use a different name, preferably unique to a single Kubernetes cluster. See the FAQ for more details.

az storage container create -n $BLOB_CONTAINER --public-access off --account-name $AZURE_STORAGE_ACCOUNT_ID

Get resource group for persistent volume snapshots

  1. Set the name of the Resource Group that contains your Kubernetes cluster’s virtual machines/disks.

    WARNING: If you’re using AKS, AZURE_RESOURCE_GROUP must be set to the name of the auto-generated resource group that is created when you provision your cluster in Azure, since this is the resource group that contains your cluster’s virtual machines/disks.


    If you are unsure of the Resource Group name, run the following command to get a list that you can select from. Then set the AZURE_RESOURCE_GROUP environment variable to the appropriate value.

     az group list --query '[].{ ResourceGroup: name, Location:location }'

    Get your cluster’s Resource Group name from the ResourceGroup value in the response, and use it to set $AZURE_RESOURCE_GROUP.

Create service principal

To integrate Velero with Azure, you must create a Velero-specific service principal.

  1. Obtain your Azure Account Subscription ID and Tenant ID:

     AZURE_SUBSCRIPTION_ID=`az account list --query '[?isDefault].id' -o tsv`
     AZURE_TENANT_ID=`az account list --query '[?isDefault].tenantId' -o tsv`
  2. Create a service principal with Contributor role. This will have subscription-wide access, so protect this credential. You can specify a password or let the az ad sp create-for-rbac command create one for you.

    If you’ll be using Velero to backup multiple clusters with multiple blob containers, it may be desirable to create a unique username per cluster rather than the default velero.

     # Create service principal and specify your own password
     az ad sp create-for-rbac --name "velero" --role "Contributor" --password $AZURE_CLIENT_SECRET
     # Or create service principal and let the CLI generate a password for you. Make sure to capture the password.
     AZURE_CLIENT_SECRET=`az ad sp create-for-rbac --name "velero" --role "Contributor" --query 'password' -o tsv`
     # After creating the service principal, obtain the client id
     AZURE_CLIENT_ID=`az ad sp list --display-name "velero" --query '[0].appId' -o tsv`

Now you need to create a file that contains all the environment variables you just set. The command looks like the following:

cat << EOF  > ./credentials-velero

Install and start Velero

Install Velero, including all prerequisites, into the cluster and start the deployment. This will create a namespace called velero, and place a deployment named velero in it.

velero install \
    --provider azure \
    --bucket $BLOB_CONTAINER \
    --secret-file ./credentials-velero \
    --backup-location-config resourceGroup=$AZURE_BACKUP_RESOURCE_GROUP,storageAccount=$AZURE_STORAGE_ACCOUNT_ID \
    --snapshot-location-config apiTimeout=<YOUR_TIMEOUT>

Additionally, you can specify --use-restic to enable restic support, and --wait to wait for the deployment to be ready.

(Optional) Specify additional configurable parameters for the --backup-location-config flag.

(Optional) Specify additional configurable parameters for the --snapshot-location-config flag.

For more complex installation needs, use either the Helm chart, or add --dry-run -o yaml options for generating the YAML representation for the installation.

Installing the nginx example (optional)

If you run the nginx example, in file examples/nginx-app/with-pv.yaml:

* Replace `<YOUR_STORAGE_CLASS_NAME>` with `default`. This is Azure's default `StorageClass` name.
