eb-env-generator.py
#!/usr/bin/env python
# On Amazon Linux 2, when you ssh into an instance, the Elastic Beanstalk environment variables are
# not set. This is annoying when trying to reproduce production issues. I dug for a while, couldn't
# find any documentation on this, then rolled my own solution. NB AL2 has Python 2 not 3 *sigh*
# Usage:
# Save this file on the instance, I suggest the name eb-env-generator.py
#
# python eb-env-generator.py
#
# This outputs a file called eb-envvars.sh which contains all the commands to set and export
# the variables to the shell
#
# . eb-envars.sh
# ^^^ Note the full stop syntax to source the file.

file.write("#!/bin/sh\n")
for key, value in vars.iteritems():
file.write("export " + key + "=\"" + value + "\"\n")
