是否可以/建议在AWS CodeBuild中使用"sam build"?

问题描述

此问题来自.现在，我对那里的问题有了更好的了解，并且可行的(如果不完善的话)解决方案，提交更具针对性的后续措施(我仍然是StackOverflow的新手-请告诉我这是否违反礼节，我应该跟进原始内容).

This question spun out of this one. Now that I have a better understanding of what was going wrong there, and a workable, if imperfect, solution, I'm submitting a more focused follow-up (I'm still something of a novice at StackOverflow - please let me know if this contravenes etiquette, and I should follow-up on the original).

此页面建议"您使用AWS CodeBuild来构建，本地测试和打包无服务器应用程序".但是，当我在 buildspec.yml 中包含 sam build 命令时，我得到以下日志输出，提示未在 sam 上安装CodeBuild图片:

This page suggests that "You use AWS CodeBuild to build, locally test, and package your serverless application". However, when I include a sam build command in my buildspec.yml, I get the following log output, suggesting that sam is not installed on CodeBuild images:

[Container] 2018/12/31 11:41:49 Running command sam build --use-container 
sh: 1: sam: not found 

[Container] 2018/12/31 11:41:49 Command did not exit successfully sam build --use-container exit status 127 
[Container] 2018/12/31 11:41:49 Phase complete: BUILD Success: false 
[Container] 2018/12/31 11:41:49 Phase context status code: COMMAND_EXECUTION_ERROR Message: Error while executing command: sam build --use-container. Reason: exit status 127 

此外，如果我使用 pip install aws-sam-cli 安装SAM，则在CodeBuild中运行 sam build --use-container 会给出错误. sam build 本身可以成功，但是由于它没有安装测试依赖项，因此我仍然需要使用 pip install -r tests/requirements-test.txt -t.以便能够在CodeBuild中运行测试.此外，此建议具有本地编译程序的程序包(em> ")需要-use-container .

Furthermore, if I install SAM with pip install aws-sam-cli, running sam build --use-container in CodeBuild gives an error. sam build itself succeeds, but since it doesn't install test dependencies, I'd still need to use pip install -r tests/requirements-test.txt -t . to be able to run tests in CodeBuild. Moreover, this suggests that --use-container is required for "packages that have natively compiled programs").

这使我想知道我是否正在尝试做错什么.在AWS的CI/CD工作流程中构建SAM服务的推荐方式是什么?

This makes me wonder whether I'm trying to do something wrong. What's the recommended way of building SAM services in a CI/CD workflow on AWS?

2019_10_18 - Update (confirming @Spiff answer above):

显然，Codebuild现在可以与SAM无缝协作，这就是我在 buildspec.yml 中使用 pandas 和 psycopg2-binary 进行lambda所需的全部工作:

Apparently Codebuild now work seamlessly with SAM, that's all I needed in buildspec.yml for a lambda using pandas and psycopg2-binary:

version: 0.2

phases:
  install:
    runtime-versions:
      python: 3.7

  pre_build:
    commands:
      - python -m unittest discover tests

  build:
    commands:
      - sam build

  post_build:
    commands:
      - sam package --output-template-file packaged.yaml --s3-bucket my-code-pipeline-bucketz

artifacts:
  type: zip
  files:
    - packaged.yaml
