Hi danishmirza,
unfortunately this gist is very old. I think in the meantime AWS changed the structure in their Elastic Beanstalk instances. Do you have a chance to find out the directory for the environment variables on AWS instance?
Then you need to replace /opt/elasticbeanstalk/support/envvars with the current path.

Or you need to create the envvars file first.
See https://aws.amazon.com/premiumsupport/knowledge-center/view-environment-properties-elastic-beanstalk/

@danishmirza
I just found an article in stackoverflow for Amazon Linux 2 instances. It's a little bit different from Amazon 1 instances.
You need to do something like this:

export $(cat /opt/elasticbeanstalk/deployment/env | xargs)

See https://stackoverflow.com/questions/63280543/aws-eb-deploy-doesnt-load-environment-variables

Good morning everybody, thank you for your good work. please I want to ask how can i Restart supervisor main process which has started by /usr/bin/python /usr/local/bin/supervisord --pidfile /var/run/supervisord.pid. thank you for your answer.

Hi @kprosper, you can create a new pre- or post-deploy script (see supervisor.config for examples)
In this script you can try to run service supervisor restart or
supervisorctl restart <name>

@johnyvelho Cool, thanx for the update and your work.
