Expanding K8s PVs in EKS on AWS

If that post title isn't a mouthful...

I'm excited to be moving a few EKS clusters into real-world production use after a few months of preparation. Besides my Raspberry Pi Dramble project (which is pretty low-key), these are the only production-grade Kubernetes clusters I've dealt with—and I've learned a lot. Enough that I'm working on a new book.

Anyways, back to the main topic: As of Kubernetes 1.11, you can auto-expand PVs from most cloud providers, AWS included. And since EKS now runs Kubernetes 1.11.x, you can have your EBS PVs automatically expand by just increasing the PVC claim size in spec.resources.requests.storage to a larger size (e.g. 10Gi to 20Gi).

To make sure this works, though, you need to make sure of a few things:

Make sure you have the proper setting on your StorageClass

You need to make sure the StorageClass you're using has the allowVolumeExpansion setting enabled, e.g.:

DIY: Greenscreens and Backdrop or Background Stands

This article will explain how to design and assemble bluescreens, greenscreens and backdrops for photos and video, as well as how to easily and inexpensively build a portable frame to support these backdrops (or other things like quilts, etc.) out of PVC pipe or metal conduit. (NOTE: Please be sure to read some of the extra notes at the bottom of this guide for optimal performance).
