如何让 Terragrunt 自动设置 "AWS_PROFILE" 环境变量？

Question

我这辈子都做不到。我需要设置 AWS_PROFILE 环境变量才能将 terrag运行t 正确设置为运行。如果我运行:

export AWS_PROFILE=myprofile; terragrunt plan

那行得通，但这不是我想要的运行:

terragrunt plan

并让它自动选择我应该使用的正确 aws 配置文件。这是我拥有的：

generate "provider" {
  path = "provider.tf"
  if_exists = "overwrite_terragrunt"
  contents = <<EOF
provider "aws" {
  region  = "${local.region}"
  profile = "${trimspace(run_cmd("bash", "${get_parent_terragrunt_dir()}/../../set_profile.sh",local.profile))}"
}
EOF
}
remote_state {
  backend = "s3"
  generate = {
    path      = "backend.tf"
    if_exists = "overwrite"
  }
  config = {
    ...
    ...
    region         = local.region
    profile        = local.profile
    ...
    ...
  }
}

它总是向我抛出错误：

Error finding AWS credentials (did you set the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables?): NoCredentialProviders: no valid providers in chain. Deprecated.
        For verbose messaging see aws.Config.CredentialsChainVerboseErrors

set_profile.sh 脚本如下：

#!/bin/bash

VALUE=$(echo  | sed $'s/\r//')
export AWS_PROFILE=$VALUE
echo "$AWS_PROFILE"

如果我回显我的 AWS_PROFILE 它仍然是空白的。所以这就像运行命令实际上并没有将导出值保存到我的控制台。

我做错了什么？有没有人真正成功地使用 terrag运行t 动态设置他们的 AWS_PROFILE？

Answer 1

这就是我的解决方案。我有以下结构：

<project>
    |-- <region1>
    |-- <region2>
    |-- account.hcl
terragrunt.hcl

在account.hcl

locals {
  aws_profile_name = "myprofile"
}

主要terragrunt.hcl

locals {
  # Automatically load account-level variables
  account_vars = read_terragrunt_config(find_in_parent_folders("account.hcl"))

  aws_profile = local.account_vars.locals.aws_profile_name
}

terraform {
  extra_arguments "aws_profile" {
    commands = [
      "init",
      "apply",
      "refresh",
      "import",
      "plan",
      "taint",
      "untaint"
    ]

    env_vars = {
      AWS_PROFILE = "${local.aws_profile}"
    }
  }
}

remote_state {
  ...
  config = {
    ...
    profile = "${local.aws_profile}"
  }
}

generate "provider" {
  ...
  contents 
  contents  = <<EOF
provider "aws" {
  profile = "${local.aws_profile}"
}
EOF
}
...

这个 post 帮助我解决了我的问题：

我忘记了我的配置有 2 个要设置的 AWS 连接

后端
提供商

因此 AWS 配置文件必须设置两次：

在remote_state

remote_state {
  backend = "s3"
  config = {
    ...
    profile = local.profile
    ...
  }
}

在provider.tf

generate "provider" {
  path      = "provider.tf"
  if_exists = "skip"
  contents  = <<EOF
provider "aws" {
  ...
  profile = "${local.profile}"
  ...
}
EOF
}

希望这能拯救我今天浪费的所有时间！
