如何在 Hashicorp Terraform 中配置环境变量 [英] How to configure environment variables in Hashicorp Terraform

问题描述

我对 Terraform 还是很陌生，尽管我已经浏览了 Hashicorp 网站上提供的所有教学模块.

I'm quite new to Terraform, though I have gone through all of the instructional modules available on Hashicorp's site.

目前，我正在努力理解如何设置环境变量.我知道如何在 main.tf 配置 (access_key = "${var.access_key}") 中引用变量，并且我知道如何将该访问密钥保存到一个单独的文件并引用它，但是我不明白(也找不到任何文档/说明)是如何设置环境变量，这样我就不必将访问密钥保存到文件中.

Currently, I'm struggling with understanding how to set up environment variables. I know how to reference variables in the main.tf config (access_key = "${var.access_key}"), and I know how to save that access key to a separate file and reference that, but what I don't understand (and can't find any documentation/instruction on) is how to set up environment variables so I don't have to save the access key to a file.

有谁知道如何最好地去做这件事?

Does anyone know how best to go about doing this?

推荐答案

Terraform 可以为 AWS 推断以下环境变量

Terraform can infer the following environment variables for AWS

export AWS_ACCESS_KEY_ID="anaccesskey"
export AWS_SECRET_ACCESS_KEY="asecretkey"

参考:https://www.terraform.io/docs/providers/aws/#environment-variables

但我建议尝试AWS Profile.您可以将凭据添加到 ~/.aws/credentials 文件中，例如

But I would suggest trying the AWS Profile. You can add credentials to ~/.aws/credentials file like

[myprofile]
aws_access_key_id     = anaccesskey
aws_secret_access_key = asecretkey

然后你可以设置环境变量export AWS_PROFILE=myprofile.现在，如果您从此 shell 运行 terraform，它应该选择 myprofile 下列出的凭据.

and then you can set environment variable export AWS_PROFILE=myprofile. Now, if you run terraform from this shell, it should pick credentials listed under myprofile.

此外，您可以让您的 AWS Provider 代码如下:

Also, you can have you AWS Provider code as follows:

provider "aws" {
  profile = "myprofile"
  region  = "${var.region}"
}

根据我的经验，使用 profile 与 AWS 交互比在每个 shell 上设置环境变量更容易且更好.

In my experience, interacting with AWS using profile is easy and better than setting environment variables on each shell.

您可以在此处参考示例 https://github.com/pradeepbhadani/tf-examples/blob/master/ex2/provider.tf
