How to provision Kubernetes Persistent Volumes to use with S3 or DO spaces


I’m a beginner on k8s and I’ve been struggling for a long time trying to do Kubernetes storage the right way. I’ve learnt that stateless applications offers great performances and database shouldn’t be inside pods for performance/availability reasons.

So is there a way to use a S3-compatible API (like DO spaces) as a storage backend ? Ideally, I’d like to migrate my databases out of k8s in a managed SQL cluster, and use object storage for my newly created PVs. I could just use S3 directly in my applications, but this is sometimes not compatible with the design of the app (e.g: Nextcloud).

If I’m understanding your question, I think all you need to do is provide your application with configuration parameters to connect to whatever storage you need.

For example, in most of my applications, I’ll create a kubernetes secret that has my database name/address/password/etc., and then I’ll provide that data to my stateless pod as an environment variable. The application can then read the environment variable and connect to the database.
