For a database deployed in a Kubernetes cluster, use StatefulSet controllers. We do not recommend running stateful services with persistent volumes in Kubernetes. To work with databases of stateful applications, use Yandex Cloud managed databases, e.g., Managed Service for MySQL® or Managed Service for PostgreSQL.

How do I connect a pod to managed Yandex Cloud databases?How do I connect a pod to managed Yandex Cloud databases?

To connect to a Yandex Cloud managed database in the same network, specify its host name and FQDN.

To connect a database certificate to a pod, use the secret or configmap objects.

You can choose how to attach Compute Cloud disks depending on your use case:

• If you need Kubernetes to automatically provision a PersistentVolume and configure a new disk, create a pod with a dynamically provisioned volume.
• To use existing Compute Cloud volumes, create a pod with a statically provisioned pod.
