All folders correspond to a blog post's code, except double_advanced_working, which is a working example (but lacking environment variables)
##single_simple
basic intro to docker-compose, a single webapp running a single stack, a sample, not runnable
##single_intermediate
a slightly more complex intro to docker-compose, introduces environment variables
##double_advanced
an example that tosses in a reverse proxy on top of two webapp stacks
##double_advanced_working
a working example that demonstrates working use of a reverse proxy on top of 3 static nginx servers,
used to demonstrate the important concepts of double_advanced without getting bogged down in complexities
