This FAQ can help if you’re just looking for a quick answer to a question.
Astra aims to simplify your application data lifecycle management operations for Kubernetes native applications. Astra supports Kubernetes clusters running on Google Kubernetes Engine (GKE) on Google Cloud Platform (GCP).
The following sections provide answers to some additional questions that you might come across as you use Astra. For any additional clarifications, please reach out to email@example.com
Access to Astra
Why do I need to provide so many details when registering for Astra?
Astra 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?
Astra 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 URL?
You can access Astra at https://astra.netapp.io.
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 firstname.lastname@example.org, or search their inbox for "invitation." You can also remove the user and attempt to re-add them.
I upgraded to the Premium Plan from the Free Plan. Will I get charged for the first 10 applications?
Yes. After upgrading to the Premium Plan, Astra starts charging you for all managed applications in your account.
I upgraded to the Premium 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 used from Cloud Volumes Service for GCP?
Yes, you will be charged for the Persistent Volumes used from Cloud Volumes Service for Google Cloud.
Registering Kubernetes clusters
Can I add a private cluster to Astra?
Yes, you can add private clusters to Astra. To create a Google Kubernetes Engine (GKE) private cluster, follow the instructions in this knowledgebase article.
Private clusters must have the master authorized network set to allow the Astra IP addresses:
Can my GCP cluster reside on a shared VPC?
Yes. If you are using a shared VPC for your GCP cluster, that shared VPC must be set up with private services access to CVS. You will need to specify the Astra service account as a member of the host project with the Compute Network Viewer role.
Where can I find my service account credentials on GCP?
Do I need to install CSI drivers on my GKE cluster before adding it to Astra?
No. When your GKE cluster is added to Astra, 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 backed by NetApp Cloud Volumes Service for Google Cloud.
I would like to add different GKE clusters from different GCP projects. Is this supported in Astra?
No, this isn’t a supported configuration. Only a single GCP project is supported.
I need to add worker nodes to my GKE cluster after adding to Astra. 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. If the new nodes are not visible in Astra, 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.
What happens to my applications and data after removing the GKE cluster from Astra?
Removing a GKE cluster from Astra will not make any changes to the cluster’s configuration (applications and persistent storage). Any Astra snapshots or backups taken of applications on that cluster will be unavailable to restore. Volume snapshot data stored within Cloud Volumes Service will not be removed. Persistent Storage backups created by Astra will remain within the Google Cloud object store, but they are unavailable for restore.
|Always remove a cluster from Astra before you delete it through GCP. Deleting a cluster from GCP while it’s still being managed by Astra can cause problems for your Astra account.|
Will NetApp Trident be uninstalled when I remove a GKE cluster from Astra?
Trident will not be uninstalled from a cluster when you remove it from Astra.
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.
I don’t see any of my application’s PVCs bound to GCP CVS. What’s wrong?
The NetApp Trident operator sets the default storage class to
netapp-cvs-premium after it’s successfully added to Astra. When an application’s PVCs are not bound to Cloud Volumes Services for Google Cloud, there are a few steps that you can take:
kubectl get scand 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.
Can Astra deploy an application?
Astra doesn’t deploy applications. Applications must be deployed outside of Astra.
What happens to applications after I stop managing them from Astra?
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.
Can Astra manage an application that is on non-NetApp storage?
No. While Astra can discover applications that are using non-NetApp storage, it can’t manage an application that’s using non-NetApp storage.
Data management operations
Where is my object bucket created?
The geography of the first managed cluster will determine the location of the object store. For example, if you add a cluster in a European zone, then remove that cluster and add one in the US, all future object stores will be created in EU. If you need to change this zone, please contact our support department.
There are snapshots in my account that I didn’t create. Where did they come from?
In some situations, Astra 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 take snapshots and backups of all these PVCs?
Yes. A snapshot operation on an application by Astra includes snapshot of all the PVs that are bound to the application’s PVCs.
Can I manage snapshots taken by Astra directly through the Cloud Volumes Service snapshot management interface or object storage?
No. Snapshots and backups taken by Astra can only be managed with Astra.
