Traefik rate limit example

This is a test for the traefik rate limiter functionality like described here:

• https://docs.traefik.io/configuration/commons/#rate-limiting

Using the docker labels like described here:

• https://docs.traefik.io/configuration/backends/docker/#using-docker-compose

Benchmarks are done with apache benchmark: (part of apache2-utils)

• https://httpd.apache.org/docs/2.4/programs/ab.html

Testing the rate limit

• add foo.bar as domain to /etc/hosts

127.0.0.1 foo.bar

• start stack with deploy.sh

./deploy.sh

• benchmark with rate limit from traefik

ab -c1 -n500 -l http://foo.bar/

• benchmark nginx directly

ab -c1 -n500 -l http://foo.bar:7080/

• inspect service labels of webservice service

docker service inspect gateway_webservice

• inspect container labels of webservice tasks

docker inspect $(docker ps |grep hello|cut -d" " -f1)

Discussion about this can be found here:

• traefik/traefik#4576

The right way to use the rateLimit for docker stack services is to use them as deploy labels in the affected services and replacing by some arbitrary name. You can stack multiple rateLimits for an service by using multiple names.
