Cluster Sim

A project to learn about simulating http traffic to a Go server and load balancing with NGINX using a Raspberry Pi 4 cluster

Tech

• Golang for a simple http server with a few endpoints serving very basic JSON data
• wrk - HTTP benchmarking
• NGINX - Load balancing

Current setup

• Docker Desktop to run wrk Docker Image
• x2 Raspberry Pi 4 Model B 2GB - Raspberry Pi OS Lite 2020-05-27

Current progress

• NGINX installed on Pi 1
• Go server binary running on both Pis in the cluster

Notes

• server.go build command on Windows to run on Pi - env GOOS=linux GOARCH=arm GOARM=6 go build Full setup instructions for cloning and contributions to come
• NGINX Pi start sudo /etc/init.d/nginx start
