This kind of thing terrifies me, so we made a conscious decision not to have any permanent data stored in the cluster, and avoid PVCs whenever possible. Having a “stateless” cluster actually has some other benefits, upgrading to new K8s versions are easy, we just spin up a new EKS cluster and terminate the old one in a blue/green process.

We do the same thing as well

I've had software engineers tell me "K8s is pretty simple" and "you can set it up in a day" Just because something can be set up quickly does not make it simple!

Day 1 can be simple, day 2 well that's were the hard journey begins 😂

PVC's are scary. I wonder if S3/volumes are going to make managing and persisting data much smoother in the future https://aws.amazon.com/about-aws/whats-new/2023/03/mountpoint-amazon-s3/

There's a reason why there are a ton of blogs on how to setup a cluster but not a lot on day to day ops/maintenance of them 😁
