Yeah. They must be. I’ve had several k8s enthusiast dissuade from putting a db in k8s for performance reasons. This may change overtime but I believe there is a performance bottleneck in disk I/o (or at least that’s how it was explained to me)

That really depends on your k8s environment. If you're running on bare metal and use host bind mounts for storage, you won't have a problem. But as soon as you introduce shared storage it gets messy...

Doesn't that defeat the promise of k8 in the first place?

Because then it won't scale.

And the moment you do you run into other bottlenecks.

Meh, not having to worry about configuring load balancers and letsencrypt alone is worth the effort to get k8s running.
