Debug Output

NOTE: In addition to Terraform debugging, please set HELM_DEBUG=1 to enable debugging info from helm.

Panic Output

Steps to Reproduce

terraform apply

Expected Behavior

Set nodeSelector metadata to "node.kubernetes.io/lifecycle" : "normal"

Actual Behavior

Error: error validating "": error validating data: ValidationError(Deployment.spec.template.spec.nodeSelector): invalid type for io.k8s.api.core.v1.PodSpec.nodeSelector: got "array", expected "map"

on ../../terraform-kubernetes-aws-eks/alb_controller.tf line 9, in resource "helm_release" "aws_load_balancer_controller": 9: resource "helm_release" "aws_load_balancer_controller" {

Important Factoids

EKS Version :1.18 chart : aws-alb-balancer-controller Use 2 types of nodes, ondemand with lifecycle = normal and spot for lifecycle=spot Since this is a essential service it needs to run on normal lifecycle

Exactly same problem occurs with tags since defaultTags is supposed to be a map. So there should be a way of specifiying maps as input instead of just strings.
