Load balancing with haproxy

Project was made to compare performance of haproxy algorithms depending on the web application usage frequency

Requirements

To run project you will need:

• docker
• docker-compose

Usage

Firstly you will need to build node-app container

cd node-app
docker build -t node-app .

Next you need to init docker swarm

docker swarm init

Last step will run the application

sudo docker stack deploy -c docker-compose.yml haproxy

If everything is setup correctly you should be able to

$ sudo docker service ls
[sudo] password for piotr: 
ID                  NAME                MODE                REPLICAS            IMAGE                        PORTS
gsalhcohjkzi        haproxy_app         replicated          3/3                 node-app:latest              *:30001->8080/tcp

Application server will run on you localhost

$ for i in {1..10}; do printf "$(curl -s -X GET http://localhost:12001)\n"; done;
