Use this guide to remove a data plane cluster from your Astro Private Cloud (APC) control plane.
This removes the control plane association. Now, platform services no longer target this data plane cluster.
Deregistering a data plane cluster doesn’t delete existing platform resources such as namespaces, services, or persistent volumes in your cloud environment. If you want to fully remove these resources, you must manually delete the Helm release.
You can also deregister a data plane cluster by calling the deregisterCluster mutation on the APC API. Send the request to https://houston.<your-base-domain>/v1 with a system service account or System Admin user token in the Authorization header. For details, see Authenticate to the APC API.
Argument reference:
This permanently deletes the cluster record from the control plane. As with the UI flow, deregistration doesn’t delete platform resources running in the data plane Kubernetes cluster (namespaces, services, persistent volumes). Remove those by uninstalling the data plane Helm release.
If you deregistered your data plane cluster by mistake, you can register the same data plane cluster again.
