how to delete an object before inserting?

[marcellodesales]

Describe the bug

• Re-running terraform apply fails with the following:

Error: customresourcedefinitions.apiextensions.k8s.io "targetgroupbindings.elbv2.k8s.aws" already exists
  on k8s_system_load_balancer_controller_install.tf line 37, in resource "k8s_manifest" "load_balancer_controller_crds":
  37: resource "k8s_manifest" "load_balancer_controller_crds" {

Steps to reproduce the issue:

• Get an object for applying

data "http" "load_balancer_controller_crds" {
  url = "https://github.com/aws/eks-charts/raw/master/stable/aws-load-balancer-controller/crds/crds.yaml"
}

resource "k8s_manifest" "load_balancer_controller_crds" {
  content   = data.http.load_balancer_controller_crds.body
  namespace = kubernetes_service_account.load_balancer_controller.metadata.0.namespace
}

Expected behavior

• Maybe execute kubectl delete before doing kubectl apply?
  • To update I usually do

curl -o https://......./crd.yaml URL && \
    kubectl delete -f crd.yaml  && \
    kubectl apply -f crd.yaml
