A customer asked: > Do the Gruntwork EKS modules support spot instances? I'm currently using self-managed node groups.

There is support for spot instances via the capabilities provider feature (see https://github.com/gruntwork-io/terraform-aws-eks/blob/master/examples/eks-cluster-with-iam-role-mappings/main.tf#L166), but it isn’t thoroughly tested. That said, we know of at least two customers who are making use of it with success.
