无法在 AWS Codebuild 中运行“源" [英] Cannot run `source` in AWS Codebuild

问题描述

我正在使用 AWS CodeBuild 和 Terraform 来自动部署基于 Lambda 的服务.我有一个非常简单的 buildscript.yml 可以完成以下任务:

I am using AWS CodeBuild along with Terraform for automated deployment of a Lambda based service. I have a very simple buildscript.yml that accomplishes the following:

• 获取依赖项
• 运行测试
• 获取 AWS 凭证并保存到文件(详见下文)
• 获取 creds 文件
• 运行 Terraform

获取凭据文件"步骤是我遇到困难的地方.我有一个简单的 bash one-liner，它从 curl 169.254.170.2$AWS_CONTAINER_CREDENTIALS_RELATIVE_URI 中获取 AWS 容器凭据，然后将它们保存到以下格式的文件中:

The step "source the creds file" is where I am having my difficulty. I have a simply bash one-liner that grabs the AWS container creds off of curl 169.254.170.2$AWS_CONTAINER_CREDENTIALS_RELATIVE_URI and then saves them to a file in the following format:

export AWS_ACCESS_KEY_ID=SOMEACCESSKEY
export AWS_SECRET_ACCESS_KEY=MYSECRETKEY
export AWS_SESSION_TOKEN=MYSESSIONTOKEN

当然，显而易见的步骤是简单地 source 这个文件，以便可以将这些变量添加到我的环境中供 Terraform 使用.但是，当我执行 source/path/to/creds_file.txt 时，CodeBuild 会返回:

Of course, the obvious step is to simply source this file so that these variables can be added to my environment for Terraform to use. However, when I do source /path/to/creds_file.txt, CodeBuild returns:

[Container] 2017/06/28 18:28:26 Running command source /path/to/creds_file.txt
/codebuild/output/tmp/script.sh: 4: /codebuild/output/tmp/script.sh: source: not found

我曾尝试通过 apt 安装 source，但随后我收到一条错误消息，提示找不到 source(是的，我已经运行 apt update 等).我将标准 Ubuntu 映像与 Python 2.7 环境一起用于 CodeBuild.我该怎么做才能在 Codebuild 中获取 Terraform 工作凭据以获取此凭据文件.

I have tried to install source through apt but then I get an error saying that source cannot be found (yes, I've run apt update etc.). I am using a standard Ubuntu image with the Python 2.7 environment for CodeBuild. What can I do to either get Terraform working credentials for source this credentials file in Codebuild.

谢谢！

推荐答案

尝试使用 . 而不是 source.source 不符合 POSIX.ss64.com/bash/source.html

Try using . instead of source. source is not POSIX compliant. ss64.com/bash/source.html
