How do I set environment properties in AWS codestar?

Question

I created a spring project in AWS codestar. I would like to pass environment properties to my application (e.g. DATA_SOURCE_URL). I can do it in elastic beanstalk in "Configuration" -> "Software" "modify" and adding the properties. But whenever a new deployment is triggered this configuration gets reseted.

I was wondering what is the way of setting environment properties when using AWS codestar.

As it may help other people that search a solution I finally get it to work by using the Saved Configuration function in Beanstalk, and calling it via the cloud formation template.yml : EBConfigurationTemplate (from the autogenerated template.yml by codestar)

  EBConfigurationTemplate:
    [...]
    SourceConfiguration:
      ApplicationName: !Ref 'EBApplication'
      TemplateName: "Saved Configuration Name"

After that my django application was able to read the os.environ['ENV_VAR_NAME'] as well as django.config that was able to connect to an RDS (Non-managed by beanstalk) to do the migration as a container_command
