How to insert multiple nodes to pool for example (cycle, terraform issue not bigip provider I presume) ? For example I'm creating nodes in cycle (and addresses counted based on some variables):

Maybe my approach is completely wrong, so just close it if it doesn't make sense.

resource "bigip_ltm_node" "node" {
    name = "${var.project_name}-${var.dcsim_name}-${var.dc_name}${format("%03d", count.index+1)}.${var.domain}"
    address = "${var.ipv4_address}.${var.ipv4_address_index + count.index + 1}"
    count = "${var.app_count}"
}

LTM

• not working, pool is created but nodes cannot be insert in cycle \ (/Common/p_demo-web_lab) already exists in partition Common

resource "bigip_ltm_pool" "web_pool" {
  name = "p_${var.project_name}-${var.dcsim_name}_poc"
  load_balancing_mode = "round-robin"
  nodes = ["${var.ipv4_address}.${var.ipv4_address_index + 1}:${var.app_port}"]
  monitors = ["http"]
  allow_snat = false
 count = "${var.app_count}"
}

virtual

• probably bug, how to handle changes in pool if virtual already created (terraform try to delete pool but can't as it is bound to virtual)

resource "bigip_ltm_virtual_server" "vs_web" {
  name = "v_${var.project_name}-${var.dcsim_name}_${var.f5_virtual_port}_poc"
  destination = "${var.f5_virtual_ipaddress}"
  port = "${var.f5_virtual_port}"
  pool = "p_${var.project_name}-${var.dcsim_name}_poc"
  source_address_translation = "automap"
}

Or at least this should works:

f5_pool_nodes = "10.4.21.141,10.4.21.142"

OK nodes created

resource "bigip_ltm_node" "node" {
    name = "${var.project_name}-${var.dcsim_name}-poc-idc-${var.dc_name}${format("%03d", count.index+1)}.${var.domain}"
    address = "${element(split(",", var.f5_pool_nodes), count.index)}"
    count = "${length(split(",", var.f5_pool_nodes))}"
}

crash on apply

resource "bigip_ltm_pool" "ltm_pool" {
  name = "p_${var.project_name}-${var.dcsim_name}_poc"
  load_balancing_mode = "round-robin"
  nodes = ["${split(",", var.f5_pool_nodes)}"]
  monitors = "${var.f5_pool_monitor}"
  allow_snat = false
}

Sorry, i'm just idiot, this works:

variable "f5_pool_monitor" { default = "http" }
variable f5_pool_nodes = "10.0.0.2,10.0.0.3"

resource "bigip_ltm_node" "node" {
    name = "${var.project_name}-${var.dcsim_name}-${var.dc_name}${format("%03d", count.index+1)}.${var.domain}"
    address = "${element(split(",", var.f5_pool_nodes), count.index)}"
    count = "${length(split(",", var.f5_pool_nodes))}"

  name = "p_${var.project_name}-${var.dcsim_name}_demo"
  load_balancing_mode = "round-robin"
  nodes = ["${split(",", var.f5_pool_nodes)}"]
  monitors = ["${split(",", var.f5_pool_monitor)}"]
  allow_snat = false
}

resource "bigip_ltm_virtual_server" "vs_web" {
  name = "v_${var.project_name}-${var.dcsim_name}_${var.f5_virtual_port}_demo"

  port = "${var.f5_virtual_port}"
  pool = "p_${var.project_name}-${var.dcsim_name}_poc"
  source_address_translation = "automap"
}

yes, I'm an idiot, nodes, pools and virtual are created, but pool is empty

ip vs name of node, really my fault
