Support Preview Instance Types

[ellistarn]

Tell us about your request

Some AWS accounts are allowlisted for new instance types before they're publicly launched.

The new types:

• show up in DescribeInstanceTypes
• show up in DescribeInstanceTypeOfferings
• do not show up in pricing.GetProducts
• are rejected by the CreateFleetAPI with PriceCapacityOptimized or LowestPrice strategies

One design option

• Support preview instance types for on-demand only
• Move to Prioritized allocation strategy, and order them ourselves
• Shim out the price, to weigh heavily away, e.g. assume math.MaxInt32

Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?

I want to try new instance types with Karpenter.

Are you currently working around this issue?

Waiting for the release.

Please ensure that these instance types are in this list before using them: https://github.com/aws/amazon-vpc-cni-k8s/blob/master/misc/eni-max-pods.txt Otherwise instances will fail anyway...
