Nginx Router Comparison

Runs a simple application in four different scenarios: Direct access (no container, no router router), app inside a container, simple nginx router (proxy) and dynamic-upstream proxy (nginx + lua).

After starting de desired application, run your benchmark against localhost:4000.

Running the applications:

Direct access:

cd server
bundle install
ruby server.rb -e production -p 4000 puma

App in container:

cd server
docker build -t app .
docker run -p 4000:4000 -d app

App in container + Nginx Proxy:

docker network create routing
cd server
docker build -t app .
docker run -d --net=routing --name application app
cd ../nginx-default
docker build -t nginx-default .
docker run -p 4000:4000 -d --net=routing nginx-default

Dynamic router with 2 app containers (blue and green):

docker network create routing
docker run -p 6379:6379 --name redis --net=routing -d redis
cd server-blue
docker build -t app-blue .
docker run -d --net=routing --name app-blue app-blue
cd ../server-green
docker build -t app-green .
docker run -d --net=routing --name app-green app-green
cd ../nginx-lua
docker build -t nginx-lua .
docker run -p 4000:4000 -d --net=routing nginx-lua

EXTRA - router switch example (depends on nginx-lua above):

• Run a simple loop to watch the response changing. In a separate terminal: while true; do curl localhost:4000; done;
• Run the sample deploy script cd deploy && ruby deploy.rb
