Sinatra + Nginx + Docker compose

What is this

A little playground for trying out Nginx URL rewrites.

I needed a way to rewrite incoming URLs /api/v2/foo to remove the v2 and turn it into a parameter instead version=2. At the same time, I also needed any incoming URLs /api/foo with the version already specified to be left as-is.

This might be a useful project if:

• you need a place to spin up and test nginx configs
• you haven't seen an nginx image used without a Dockerfile
• you've never linked containers together using docker compose
• you need a super simple example of sinatra app that's wired up correctly to rackup.

Update: I wrote a blog post explaining the background behind this project.

Usage

$ make serve
# lots of boring noise as software builds

in another terminal session

$ make test
# lots of boring output...

after losing several seconds of your life, you can clean up using

$ make clean

Routes and expected outcomes

Method	Sinatra	Nginx	Params (In)	Params (Out)
GET	/api/v2/foo	/api/foo	none	version=2
POST	/api/v2/bar	/api/bar	none	version=2
GET	/api/foo	as-is	version=3	as-is
POST	/api/bar	as-is	version=3	as-is
