Now in limited availability, CoreWeave Database (CWDB) is a managed, PostgreSQL-compatible database service that runs inside a CoreWeave Kubernetes Service (CKS) cluster. CWDB uses CoreWeave Distributed File Storage (DFS) for the live database and CoreWeave-managed storage for backups. CoreWeave runs the database operator on your behalf, handles high availability, takes automatic backups, and surfaces monitoring. You can create and manage a CoreWeave Database through the CoreWeave Cloud Console, directly in Kubernetes with kubectl, through GitOps tools like Argo CD or Flux, or by writing your own controllers against the Kubernetes API. For the underlying resource model and field reference, see Configure database.

​
Request limited availability access

CWDB is enabled per CKS cluster through a feature flag managed by the CWDB team. To request enablement:
  1. Contact CoreWeave through your customer Slack channel with your CKS cluster name and the namespace or namespaces you plan to use.
  2. Wait for confirmation that the CWDB add-on is active on your CKS cluster.
To verify that you’re enabled, list the CWDB Custom Resource Definitions (CRDs):
If enabled, you should see cwdbclusters.data.coreweave.com and cwdbbackups.data.coreweave.com listed in the output.

​
Resources

CWDB exposes two Kubernetes custom resources:

CWDBCluster

A managed PostgreSQL database. Defines the topology (primary plus replicas), compute, storage, and access settings for one database. Restores from a backup are also configured on this resource, through spec.postgres.restore.

CWDBBackup

An on-demand backup of a database. Use it for known recovery points before risky operations.

Manage database

Edit a database, resize storage, or delete a database after creation.

Connect to a database

Extract connection strings and route traffic through the pooler Services.

Manage backups

How automatic backups work, how to take on-demand backups, and how to restore from a backup into a new database.
