openstack - 添加新“组件”时更新现有 terraform 计算实例

问题描述

我是 terraform 的新手，但我创建了一个这样的 openstack 计算实例：

provider "openstack" {
  auth_url    = "https://my-auth/v2.0/" 
  domain_name = "default"                         
  alias       = "alias"                              
  user_name   = "username"
  tenant_name = "tenantname"
  password    = "pwd"
  region      = "region"
}

# Import SSH key pair into openstack project
resource "openstack_compute_keypair_v2" "keypair" {
  provider   = "myprovider"               
  name       = "keypair"                 
  public_key = "${file("~/.ssh/id_rsa.pub")}"
}

# Create a new virtual machine
resource "openstack_compute_instance_v2" "compute_instance" {
  name        = "compute_instance" # Instance Name
  provider    = "myprovider"       # Instance distr
  image_name  = "Centos 7"         # Image name
  flavor_name = "b2-7"             # Machine type name

  key_pair = "${openstack_compute_keypair_v2.keypair.name}"

  network {
    name = "Ext-Net"
  }
}

出于可维护性和灵活性的原因，我想在同一个实例中添加一些“组件”，它可以是任何东西，但在这里我尝试了一个配置文件和远程执行。事实上，当我在我的计算实例中添加这个参数时，我注意到我的计算实例不会被更新。例如：

provider "openstack" {
  auth_url    = "https://my-auth/v2.0/" 
  domain_name = "default"                         
  alias       = "alias"                              
  user_name   = "username"
  tenant_name = "tenantname"
  password    = "pwd"
  region      = "region"
}

resource "openstack_compute_keypair_v2" "keypair" {
  provider   = "myprovider"               
  name       = "keypair"                 
  public_key = "${file("~/.ssh/id_rsa.pub")}"
}

resource "openstack_compute_instance_v2" "compute_instance" {
  name        = "compute_instance" # Instance Name
  provider    = "myprovider"       # Instance distr
  image_name  = "Centos 7"         # Image name
  flavor_name = "b2-7"             # Machine type name

  key_pair = "${openstack_compute_keypair_v2.keypair.name}"

  network {
    name = "Ext-Net"
  }

  # Add a provisionner file on the ressource
  provisioner "file" {
    source      = "foo_scripts/bar-setup.sh"
    destination = "/tmp/bar-setup.sh"

    connection {
      type        = "ssh"
      user        = "user"
      private_key = "${file("~/.ssh/id_rsa")}"
    }
  }

  # execute server setup file
  provisioner "remote-exec" {
    inline = [
      "chmod +x /tmp/bar-setup.sh",
      "sudo bash /tmp/bar-setup.sh",
    ]

    connection {
      type        = "ssh"
      user        = "centos"
      private_key = "${file("~/.ssh/id_rsa")}"
    }
}

事实上，通过在资源上添加 provionner 文件，当我运行命令terraform plan或terraform apply时，我的实例没有任何变化。我有 infos 消息通知我：

申请完成！资源：添加 0 个，更改 0 个，销毁 0 个。

将我的更改应用于我的计算实例的正确方法是什么。
