This FAQ can help if you’re just looking for a quick answer to a question.


Astra Control aims to simplify your application data lifecycle management operations for Kubernetes native applications. Astra Control Service supports Kubernetes clusters running on Google Kubernetes Engine (GKE) and Azure Kubernetes Service (AKS).

The following sections provide answers to some additional questions that you might come across as you use Astra Control. For any additional clarifications, please reach out to

Access to Astra Control

Why do I need to provide so many details when registering for Astra Control?

Astra Control requires accurate customer information when registering. This information is required to go through a Global Trade Compliance (GTC) check.

Why am I getting a “Registration Failed” error when registering for Astra Control?

Astra Control requires you to provide accurate customer information in the onboarding section. You will get a "Registration Failed" error if you provided incorrect information. Other accounts that you are a member of also get locked.

What’s the Astra Control Service URL?

You can access Astra Control Service at

I sent an email invitation to a colleague, but they haven’t received it. What should I do?

Ask them to check their spam folder for an email from, or search their inbox for "invitation." You can also remove the user and attempt to re-add them.

I upgraded to the Premium PayGO Plan from the Free Plan. Will I get charged for the first 10 applications?

Yes. After upgrading to the Premium Plan, Astra Control starts charging you for all managed applications in your account.

I upgraded to the Premium PayGO Plan in the middle of a month. Will I get charged for the entire month?

No, billing starts from the time that you upgraded to the Premium Plan.

I am using the Free Plan, will I get charged for the Persistent Volume Claims?

Yes, you will be charged for the Persistent Volumes used by GKE clusters from Cloud Volumes Service for Google Cloud or by AKS clusters from Azure NetApp Files.

Registering Kubernetes clusters

Do I need to install CSI drivers on my cluster before adding it to Astra Control Service?

No. When your cluster is added to Astra Control, the service will automatically install NetApp’s Trident Container Storage Interface (CSI) driver on the Kubernetes cluster. This CSI driver is used to provision persistent volumes for GKE clusters backed by NetApp Cloud Volumes Service for Google Cloud, and for AKS clusters backed by Azure NetApp Files.

I need to add worker nodes to my cluster after adding to Astra Control Service. What should I do?

New worker nodes can be added to existing pools, or new pools can be created as long as they are the Ubuntu image type. These will be automatically discovered by Astra Control. If the new nodes are not visible in Astra Control, check if the new worker nodes are running the supported image type. You can also verify the health of the new worker nodes by using the kubectl get nodes command.

Registering GKE clusters

Can I add a private GKE cluster to Astra Control Service?

Yes, you can add private clusters to Astra Control Service. To create a Google Kubernetes Engine (GKE) private cluster, follow the instructions in this knowledgebase article.

Private clusters must have the authorized networks set to allow the Astra Control IP addresses:




Can my GKE cluster reside on a shared VPC?

Yes, Astra Control can manage clusters that reside in a shared VPC. Learn how to set up the Astra service account for a shared VPC configuration.

Where can I find my service account credentials on GCP?

After you log in to the Google Cloud Console, your service account details will be in the IAM and Admin section. For more details, refer to how to set up Google Cloud for Astra Control.

I would like to add different GKE clusters from different GCP projects. Is this supported in Astra Control?

No, this isn’t a supported configuration. Only a single GCP project is supported.

Removing clusters

How do I properly unregister, bring down a cluster, and delete the associated volumes?

What happens to my applications and data after removing the cluster from Astra Control?

Removing a cluster from Astra Control will not make any changes to the cluster’s configuration (applications and persistent storage). Any Astra Control snapshots or backups taken of applications on that cluster will be unavailable to restore. Volume snapshot data stored within the backend storage will not be removed. Persistent Storage backups created by Astra Control will remain within your cloud provider’s object store, but they are unavailable for restore.

Warning Always remove a cluster from Astra Control before you delete it through GCP. Deleting a cluster from GCP while it’s still being managed by Astra Control can cause problems for your Astra Control account.

Will Astra Trident be uninstalled when I remove a cluster from Astra Control?

Astra Trident will not be uninstalled from a cluster when you remove it from Astra Control.

Managing applications

Can Astra Control deploy an application?

Astra Control doesn’t deploy applications. Applications must be deployed outside of Astra Control.

My application is not showing up on the Discovered Apps list. What can I check to identify the problem?

When applications are not listed in Discovered Apps, check the status and health of the Kubernetes pod by running kubectl get pod -A |grep [pod name]. If the pods are healthy and running, check to see if the application is listed under Ignored Apps.

Can Astra Control manage an application that is on non-NetApp storage?

No. While Astra Control can discover applications that are using non-NetApp storage, it can’t manage an application that’s using non-NetApp storage.

I don’t see any of my application’s PVCs bound to GCP CVS. What’s wrong?

The Astra Trident operator sets the default storage class to netapp-cvs-premium after it’s successfully added to Astra Control. When an application’s PVCs are not bound to Cloud Volumes Service for Google Cloud, there are a few steps that you can take:

  • Run kubectl get sc and check the default storage class.

  • Check the yaml file or Helm chart that was used to deploy the application and see if a different storage class is defined.

  • Check to make sure that the worker node image type is Ubuntu and the NFS mount succeeded.

What happens to applications after I stop managing them from Astra Control?

Any existing backups or snapshots will be deleted. Applications and data remain available. Data management operations will not be available for unmanaged applications or any backups or snapshots that belong to it.

Data management operations

Where does Astra Control create the object store bucket?

The geography of the first managed cluster determines the location of the object store. For example, if the first cluster that you add is in a European zone, then the bucket is created in that same geography. If needed, you can add additional buckets.

There are snapshots in my account that I didn’t create. Where did they come from?

In some situations, Astra Control will automatically create a snapshot as part of performing another process. If these snapshots are more than a few minutes old, you can safely delete them.

My application uses several PVs. Will Astra Control take snapshots and backups of all these PVCs?

Yes. A snapshot operation on an application by Astra Control includes snapshot of all the PVs that are bound to the application’s PVCs.

Can I manage snapshots taken by Astra Control directly through my cloud provider?

No. Snapshots and backups taken by Astra Control can only be managed with Astra Control.
