使用 terraform 在 GCP 计算引擎中安装 kubectl

Question

需要在 terraform 脚本中的 metadata_startup_script 中添加多个命令以在 GCP

中启动 compute engine 实例

以下是我的代码

  metadata_startup_script = "curl -LO "https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl" ; chmod +x kubectl ; sudo cp kubectl /usr/local/bin"

terraform plan 显示以下错误

   Error: Missing newline after argument

  on main.tf line 58, in resource "google_compute_instance" "default":
  58: metadata_startup_script = "curl -LO "https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl" ; chmod +x kubectl ; sudo cp kubectl /usr/local/bin"

  An argument definition must end with a newline.

有什么解决这个问题的建议吗？任务是使用以下命令

启动 compute engine 后安装 kubectl

   curl -LO "https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl" 
   chmod +x kubectl 
   sudo cp kubectl /usr/local/bin"

你有 2 个解决方案

转义双引号 "

  metadata_startup_script = "curl -LO \"https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl\" ; chmod +x kubectl ; sudo cp kubectl /usr/local/bin"

在 TF 文件中以多行方式编写脚本

metadata_startup_script = <<SCRIPT
   curl -LO "https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl" 
   chmod +x kubectl 
   sudo cp kubectl /usr/local/bin
