如何使用 GCP 在 terraform 上添加或删除块代码 access_config 。

我有变量：

external_ip = false

如果外部 IP 值为 false 代码：

resource "google_compute_instance_from_template" "default_name_index" 
  name  = "$length(var.instances[change_with_index].instance_backup_ip) == 1 ? var.instances[change_with_index].instance_backup_name : format("%s-%s", var.instances[change_with_index].instance_backup_name, count.index + 1)"
  count = length(var.instances[change_with_index].instance_backup_ip)

  source_instance_template = "projects/$var.provider_project/global/instanceTemplates/$replace(var.instances[change_with_index].instance_name, "-app-image", "")-$var.release_version"

  network_interface 
    network    = var.instances[change_with_index].instance_network
    subnetwork = var.instances[change_with_index].instance_subnetwork
    network_ip = var.instances[change_with_index].instance_backup_ip[count.index]
    
  

如果 external_ip 的值为 true 代码：

resource "google_compute_instance_from_template" "default_name_index" 
  name  = "$length(var.instances[change_with_index].instance_backup_ip) == 1 ? var.instances[change_with_index].instance_backup_name : format("%s-%s", var.instances[change_with_index].instance_backup_name, count.index + 1)"
  count = length(var.instances[change_with_index].instance_backup_ip)

  source_instance_template = "projects/$var.provider_project/global/instanceTemplates/$replace(var.instances[change_with_index].instance_name, "-app-image", "")-$var.release_version"

  network_interface 
    network    = var.instances[change_with_index].instance_network
    subnetwork = var.instances[change_with_index].instance_subnetwork
    network_ip = var.instances[change_with_index].instance_backup_ip[count.index]
    
    #access_config will add in here
    access_config
    
    

  

谢谢你帮助我。

【参考方案1】：

您可以使用dynamic blocks 和for_each 做到这一点：

resource "google_compute_instance_from_template" "default_name_index" 
  name  = "$length(var.instances[change_with_index].instance_backup_ip) == 1 ? var.instances[change_with_index].instance_backup_name : format("%s-%s", var.instances[change_with_index].instance_backup_name, count.index + 1)"
  count = length(var.instances[change_with_index].instance_backup_ip)

  source_instance_template = "projects/$var.provider_project/global/instanceTemplates/$replace(var.instances[change_with_index].instance_name, "-app-image", "")-$var.release_version"

  network_interface 
    network    = var.instances[change_with_index].instance_network
    subnetwork = var.instances[change_with_index].instance_subnetwork
    network_ip = var.instances[change_with_index].instance_backup_ip[count.index]
    
    #access_config will add in here
    dynamic "access_config"    
    
       for_each = external_ip == false ? [] : [1]
       content 
          // the normal content of access_config
