在弹性 beanstalk 上部署多容器 docker 应用程序：找不到 webpack 命令

Question

I have a simple app consisting in a few containers behind an nginx reverse proxy. App is written in javascript and I used webpack for both front-end and back-end and additional modules. . Webpack is listed in devDependencies . I am trying to deploy this app on AWS elasticbeanstalk (at which I am totally new) in a Docker environment running on 64bit Amazon Linux 2/3.2.0 and I am facing this error:

...
somecontainer_1  | npm ERR! A complete log of this run can be found in:
somecontainer_1  | npm ERR!     /root/.npm/_logs/2020-10-19T21_35_51_966Z-debug.log
somecontainer_1  | 
somecontainer_1  | > fibworker@1.0.0 start /app
somecontainer_1  | > webpack --watch
somecontainer_1  | 
somecontainer_1  | sh: webpack: not found
somecontainer_1  | npm ERR! code ELIFECYCLE
somecontainer_1  | npm ERR! syscall spawn
somecontainer_1  | npm ERR! file sh
...

elasticbeanstalk runs npm install in production mode, so using some configuration I should be able to make elasticbeanstalk to install devDependencies and use webpack . I searched docs and read posts here and there. I tried to:

• set the environment NPM_USE_PRODUCTION to false,
• add the following ./ebextensions/something.config :

option_settings:
  - namespace: aws:elasticbeanstalk:environment
    option_name: NPM_USE_PRODUCTION
    value: false

• use the ./ebextensions/something.config suggested here . I guess I that was the right way, but causes deploy to fail with this error:

No luck. What am I missing?

Answer 1

Well what I miss is that AWS (at the time I was struggling against) does not care about dev dependencies of your node project, so my app does not fit.
