Node & Elastic Beanstalk: Set environment NODE_ENV=prod

Question

I need to execute the following command for production environment:

NODE_ENV=production node app.js

I tried passing it as a command under Configueration:

I get the following error in the logs:

sh: NODE_ENV=prod node app.js: command not found

I also tried:

NODE_ENV=prod  // 
error: sh: NODE_ENV=prod: command not found


NODE_ENV=prod app.js  // 
error: sh: NODE_ENV=prod app.js: command not found

What's the best way to execute the following command when launching the app on ELB:

NODE_ENV=production node app.js

Answer 1

You don't need to set the node command manually. Elastic Beanstalk attempts to start app.js, then server.js, and then npm start in that order. You can set the value of NODE_ENV in the "Environment Properties" section under "Configuration".

Answer 2

As others have mentioned you can manually add them by going to Configuration -> Software -> Environment properties.

A second way to do this is to add a .ebextensions/environment.config file.

1. Add the directory .ebextensions at the root of your project.
2. Create the file environment.config within .ebextensions.
3. Add your environment configurations.

Example of environment.config:

option_settings:
  - option_name: NODE_ENV
    value: production
