Setting NODE_ENV variable in elasticbeanstalk

Other ways to set environment variables in elastic beanstalk are -

1. Create a config file in .ebextensions directory like environmentalvar.config and define variables in option_settings and include this file into application bundle. (Aws Documentation)

   example -

   option_settings:
        aws:elasticbeanstalk:application:environment:
          NODE_ENV: production
   

2. By using elastic beanstalk command line tool. Command for set variable-

   eb setenv VAR_NAME=VAR_VALUE

Your .config file should be located in the .ebextensions directory, not .elasticbeanstalk.

Try it then, if that doesn't work, you can always use the console.

In the meantime, you can always use the Elastic Beanstalk Console which let's you add environment variables from its interface. To do so, just:

1. Open up your environment.
2. You'll see Dashboard, Configuration, Logs and more on the left. Click the Configuration link.
3. Then click the gear icon next to the Software Configuration block.
4. Scroll down and add a key/value for the Environment Properties.
