我已经为aws_launch_configuration资源添加了一个文件配置器，并且看到了SSH超时 .

1 error(s) occurred:

* module.dev-agooch.module.web.aws_launch_configuration.primary: timeout - last error: dial tcp :22: connect: connection refused

我确保创建的安全组允许入站ssh流量 .

这是我的相关配置：

data "template_file" "pg_service_conf" {
  template = "${file("${path.module}/pg_service_conf.tpl")}"

  vars {
    db_host = "${var.db_host}"

我正在使用Terraform v0.11.7，provider.aws v1.25.0，provider.template v1.0.0版本 .

从Terraform获取有关该问题的更多信息的最佳方法是什么？有些问题我不知道吗？

提前谢谢了！
