...when auto-scaling.

Did you want to change anything in the karpenter provisioner that we create?

I don't think so because the API hasn't changed.

That said, I don't understand how it's working now with these placeholders in there... I believe I copied them from wherever you originally had the YAML when I came up with this Helm solution. Do you know what they should be?

Yes, I don't know how they got messed up, but,

• The launch-template-name is supposed to be the same as https://github.com/GSA/datagov-brokerpak-eks/blob/52648eda4890aab6a2768bb35ca0d8e4af92f01f/terraform/modules/provision-aws/eks.tf#L109
• The cluster-name is supposed to be the same name as the eks cluster, https://github.com/GSA/datagov-brokerpak-eks/blob/52648eda4890aab6a2768bb35ca0d8e4af92f01f/terraform/modules/provision-aws/eks.tf#L2

The original solution was doing a terraform replace on those strings with correct variables.
