Apparently a GKE cluster costs $75 a month; this is the most expensive component of the cloud bill for my side project. There is a free tier ... but I recently learned it only applies to zonal clusters, not regional clusters. Much to my chagrin. The pricing docs are very unclear.
So I moved from a regional cluster to a zonal cluster. If you know kube at all you know this is not the kind of thing kube makes easy.
Hard parts about this:
- moving the storage over
- recreating the NEGs
