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

Answer 3

You need to use the "Environment Properties" Not the node command.

Key: NODE_ENV
Value: production

Answer 4

I would just set NODE_ENV in Environment Properties under the same configuration area. You can also set this in your .ebextensions config.
