For others who want to use environmental variables in this script, check out Referencing env variables from Elastic Beanstalk .ebextensions config files and
Passing custom env vars on Elastic Beanstalk.

While variables are available to the ebextensions script (which, in Ruby, would be the ENV hash), they are only available in container_commands, not commands or other config sections. That's why either preprocessing or a modification to this script is required.

I don't get it. Where am I supposed to know what version I want? The newest? What is it?

@aop I think it's just abstracting the version out to avoid having this go out of date too quickly. I chose to put in v0.16 for version after taking a look at the releases page here:

https://github.com/papertrail/remote_syslog2/releases

This config now lives in the remote_syslog2 examples directory.
