NPM问题使用AWS codedeploy部署nodejs实例

Question

我目前正在尝试通过Github和AWS Codedeploy自动将nodejs应用程序部署到EC2实例.我已经尽可能地遵循了这里的说明 ,但是我遇到了AfterInstall钩子事件.

这是我的yml文件:

version: 0.0
os: linux
files:
  - source: /backend
    destination: /home/ec2-user/signal
permissions:
  - object: /
    pattern: "**"
    owner: ec2-user
    group: ec2-user
hooks:
  ApplicationStop:
    - location: backend/app/deploy/stop.sh
      timeout: 10
      runas: ec2-user
  BeforeInstall:
    - location: backend/app/deploy/beforeinstall.sh
      timeout: 1200
      runas: ec2-user
  AfterInstall:
    - location: backend/app/deploy/afterinstall.sh
      timeout: 1200
      runas: ec2-user
  ApplicationStart:
    - location: backend/app/deploy/start.sh
      timeout: 60
      runas: ec2-user
ValidateService:
    - location: backend/app/deploy/validate.sh
      timeout: 60
      runas: ec2-user

我通过AWS CLI调用部署,如下所示:

aws deploy create-deployment --application-name Signal --deployment-config-name CodeDeployDefault.OneAtATime --deployment-group-name Production --description "Deployment" --github-location repository=githubusername/repository,commitId=ABCD123 --ignore-application-stop-failures

一切正常,直到我到达AfterInstall阶段并执行'afterinstall.sh'.那个文件看起来像这样:

#!/bin/bash
cd /home/ec2-user/signal/app/
npm install

并生成以下错误日志,导致部署失败:

错误代码: ScriptFailed

消息:指定位置的脚本:backend/app/deploy/afterinstall.sh以用户ec2-user运行失败,退出代码为127

LifecycleEvent - AfterInstall
Script - backend/app/deploy/afterinstall.sh
[stderr]/opt/codedeploy-agent/deployment-root/be9902d2-8af0-46fd-b186-23ead6bea5a4/d-SBW6YCLKC/deployment-archive/backend/app/deploy/afterinstall.sh: line 7: npm: command not found

但是,如果我ssh到我的ec2实例,导航到临时目录:

/opt/codedeploy-agent/deployment-root/be9902d2-8af0-46fd-b186-23ead6bea5a4/d-SBW6YCLKC/deployment-archive/backend/app/deploy/

要么

cd /home/ec2-user/signal/app/

并手动运行'npm install',或通过./afterinstall.sh运行我的脚本,然后npm运行正常.

为什么Codedeploy代理有不同之处？我正在使用'runas:ec2-user',所以我假设权限等与我作为ec2-user进入盒子时的权限相同.

我做错了什么愚蠢的事情？非常感谢.

正如mbaird和Chris在评论中准确指出的那样 - 我没有设置PATH.所以npm,node,pm2和...都失败了.

通过实验,我似乎需要在Codedeploy部署过程的每一步中重新建立我的路径.所以在我的stop.sh/beforeinstall.sh/afterinstall.sh/start.sh的顶部,我包括:

source /home/ec2-user/.bash_profile

生活很美好.然后我遇到了其他问题,pm2没有在正确的工作目录中启动节点,但是对codedeploy脚本进行了类似的调整.

事后来看,这一切都很明显,但我非常感谢你的帮助.感谢你们!
