Docker example - Boilerplate

[gabrielhesposito]

My hope is that this image can be throughly documented so remote_syslog2 (rs2) can have a docker image for contributors to build on.

docker build --build-arg VERSION=v0.19 -t rs2 .
run (in background, docker ps to confirm)
docker run --name rs2 -d rs2
TODO: Documentation
This baseplate should have documentation that only corresponds to the docker CLI, very basic starting/stop/removing containers, confirming that logs send correctly + simple exampling, passing ENV variables to container to manipulate remote_syslog2 cli

Should I create documentation in this PR, or create a new fork ?

Hi @gabrielhesposito,

Thanks for the example! Documentation in this PR would be fine, no need for another one. Can you outline your motivations for this, and how you envision it being used?

[gabrielhesposito]

So my motivation for the Dockerfile meaning... a proper use-case for remote_syslog2+docker, why and when it should be shipped with docker- maybe a docker network command to help troubleshoot connection issues...ok ill add documentation into the root README.md on this PR

[gabrielhesposito]

@snorecone too many commits in this PR...besides that I am happy with the example and the documentation
