v0.10.2 Not supporting Spot Instances?

[techtransplant]

What happened?
I ran eksctl create cluster -f cluster.yaml and got this error:

2019-11-23T16:10:03-08:00 [✖]  loading config file "cluster.yaml": error unmarshaling JSON: while decoding JSON: json: unknown field "instancesDistribution"

What you expected to happen?
I should be able to configure my cluster to use spot instances, as I could in previous versions of eksctl

How to reproduce it?
Use this yaml config and do eksctl create cluster -f cluster.yaml

apiVersion: eksctl.io/v1alpha5
kind: ClusterConfig

  name: lee
  region: us-west-2

    iam:
      withAddonPolicies:
        autoScaler: true

Anything else we need to know?
What OS are you using, are you using a downloaded binary or did you compile eksctl, what type of AWS credentials are you using (i.e. default/named profile, MFA) - please don't include actual credentials though!

Versions
Please paste in the output of these commands:

$ eksctl version
[ℹ]  version.Info{BuiltAt:"", GitCommit:"", GitTag:"0.10.2"}
$ kubectl version
Client Version: v1.16.3

Ok, I see that instancesDistribution field is not supported in the docs. Does that mean managed nodegroups cannot use spot instances?

@EightLimbed you are correct.
You can follow the status of this feature here: aws/containers-roadmap#583

thanks for explaining @fmedery -- I'll close this issue.
