将许多ENV传递到terraform模板

Question

是否可以将许多ENV一起传递到Terraform中的模板文件，而不必像这样分别声明它们：

data "template_file" "test_template" {
  template = file("templates/container.tpl")
  vars = {
    ENV1 = var.ENV1
    ENV2 = var.ENV2
    ENV3 = var.ENV3
    ENV4 = var.ENV4
    ENV5 = var.ENV5
  }
}

在模板中是否像这样？

[
  {
    "essential": true,
    "memory": 300,
    "name": "client",
    "cpu": 300,
    "image": "some_image",
    "portMappings": [
        {
            "containerPort": 3000,
            "hostPort": 0
        }
    ],
    "environment": [
      { "name": "ENV1", "value": "${ENV1}" },
      { "name": "ENV2", "value": "${ENV2}" },
      { "name": "ENV3", "value": "${ENV3}" },
      { "name": "ENV4", "value": "${ENV4}" },
      { "name": "ENV5", "value": "${ENV5}" },
    ]
  }
]

在Terraform 0.12中，建议您使用：

https://www.terraform.io/docs/configuration/functions/templatefile.html

模板：

ctrl + shift + o

致电：

%{ for addr in ip_addrs ~}
backend ${addr}:${port}
%{ endfor ~}
