For_each loop over objects in a map "Error: Cycle:"

Terraform

Hi @apparentlymart,

So someone was able to help me out and I got it working just how I want it. And this is the code. Hopefully this also explains a bit what I was trying to achieve.

terraform {
  required_providers {
    lxd = {
      source = "arren-ru/lxd"
      version = "1.4.0"
    }
  }
}

provider "lxd" {
  generate_client_certificates = true
  accept_remote_certificate = true

  lxd_remote {
    name = "lxd-01"
    scheme = "https"
    address = "X"
    password = "X"
    default = true
  }
}


locals {
  images = [
    { alias = [ "ubuntu_focal" ],  source_remote = "ubuntu", source_image = "focal/amd64" },
    { alias = [ "debian_buster" ], source_remote = "images", source_image = "debian/10/amd64" }
  ]
  image_fingerprints = {
    for image in lxd_cached_image.image:
      image.aliases[0] => image.fingerprint
  }
  containers = [
    { name = "unifi", image = "ubuntu_focal" },
    { name = "grafana", image = "debian_buster" },
    { name = "test1", image = "debian_buster" }

  ]
}

resource "lxd_cached_image" "image" {
  count         = length(local.images)
  aliases       = lookup(local.images[count.index], "alias")
  source_remote = lookup(local.images[count.index], "source_remote")
  source_image  = lookup(local.images[count.index], "source_image")
}


resource "lxd_container" "create_container" {
  count = length(local.containers)

  name = lookup(local.containers[count.index], "name")
  image = lookup(local.image_fingerprints, lookup(local.containers[count.index], "image"))
  ephemeral = false

  config = {
    "boot.autostart" = true
  }
}
