How to specify sensitive environment variables at deploy time with Elastic Beanstalk

Question

I am deploying a Python Flask application with Elastic Beanstalk. I have a config file /.ebextensions/01.config where among other things I set some environment

Answer 1

You should be able to specify sensitive values as environment variables from eb web console: Your EB app -> Your EB environment -> Configuration -> Software Configuration -> Environment Properties
