如何使用 terraform 向 GCP 实例添加 ssh 密钥? [英] How to add an ssh key to an GCP instance using terraform?

问题描述

所以我有一个在 Google Cloud Platform 中创建实例的 terraform 脚本，我希望能够让我的 terraform 脚本也将我的 ssh 密钥添加到我创建的实例中，以便我可以通过 ssh 配置它们.这是我当前的 terraform 脚本.

So I have a terraform script that creates instances in Google Cloud Platform, I want to be able to have my terraform script also add my ssh key to the instances I create so that I can provision them through ssh. Here is my current terraform script.

#PROVIDER INFO
provider "google" {
  credentials = "${file("account.json")}"
  project     = "myProject"
  region      = "us-central1"
}


#MAKING CONSUL SERVERS
resource "google_compute_instance" "default" {
  count    =  3
  name     =  "a-consul${count.index}"
  machine_type = "n1-standard-1"
  zone         = "us-central1-a"

  disk {
    image = "ubuntu-1404-trusty-v20160627"
  }

  # Local SSD disk
  disk {
    type    = "local-ssd"
    scratch = true
  }

  network_interface {
    network = "myNetwork"
    access_config {}
  }
}

我必须添加什么才能让我的 terraform 脚本添加我的 ssh 密钥 /Users/myUsername/.ssh/id_rsa.pub?

What do I have to add to this to have my terraform script add my ssh key /Users/myUsername/.ssh/id_rsa.pub?

推荐答案

我认为这样的事情应该可行:

I think something like this should work:

  metadata = {
    ssh-keys = "${var.gce_ssh_user}:${file(var.gce_ssh_pub_key_file)}"
  }

https://cloud.google.com/compute/docs/instances/adding-removing-ssh-keys 描述了元数据机制，我在 https://github.com/hashicorp/terraform/issues/6678

https://cloud.google.com/compute/docs/instances/adding-removing-ssh-keys describes the metadata mechanism, and I found this example at https://github.com/hashicorp/terraform/issues/6678
