Add a way to apply multiple crd resources from one file

[abdul90082]

Some charts include multiple crd resources in one file.
eg: https://raw.githubusercontent.com/Kong/charts/kong-2.13.1/charts/kong/crds/custom-resource-definitions.yaml

This seems to be not possible with your module.
What I did as a workaround:

variable "crds_urls" {
  type = list(object({
    count = string
    url   = string
  }))
  description = <<-EOF
  List of the URLs including the count of the crds per file 
  (due to terraform limitation)
  EOF
}

variable "server_side_apply" {
  type        = bool
  default     = false
  description = "Optional. Allow using server-side-apply method. Default false."
}
data "http" "yaml_file" {
  for_each = toset(var.crds_urls[*].url)
  url      = each.value

  lifecycle {
    postcondition {
      condition     = contains([200, 201, 204], self.status_code)
      error_message = "Status code invalid"
    }
  }
}

data "kubectl_file_documents" "crds" {
  for_each = toset(var.crds_urls[*].url)
  content  = data.http.yaml_file[each.value].response_body
}

locals {
  crds = flatten([
    for crd_url in var.crds_urls :
    data.kubectl_file_documents.crds[crd_url.url].documents
  ])
  crd_count = sum(var.crds_urls[*].count)
}

resource "kubectl_manifest" "crd" {
  count = local.crd_count

  # depends_on = [null_resource.status_check]
  yaml_body = local.crds[count.index]

  server_side_apply = var.server_side_apply
}

But this needs the count to be known before the apply so it's not perfect.
Any idea how to implement this?

Hi Abdul,
thanks for your patience on this.

Nothing simple comes to my mind, but it could be indeed an interesting feature. If somebody has any idea, please share it 😄

If I find a simple solution, I'll implement it.

Ran into this issue while using the module to install cert-manager crds. Threw for a bit of a loop.
