Ah. Yeah I'm setting things up with managed node groups and it doesn't seem so bad so far... Waiting for the other shoe to drop after so much doom saying though haha. Luckily we removed the need for anything stateful, so I can ignore the EBS-CSI shortcomings. Also trying to keep it simple/minimal when it comes to ingress and networking.
Cool. I've never had any issue with EBS CSI driver itself, the biggest issue were idiosyncracies of EBS itself, like the mount count limit or availability zone requirements. These need ugly workarounds, like limiting your volumes to a single AZ, so, no HA.
On the other side, their VPC CNI plugin and their ingress controller are pretty much set and forget.
Yeah basically it is that EBS limitation (AZ-specific) combined with autoscaling causing quirky failure modes unless you are careful about how you set things up.
