Buoy

Buoy is simple containerized web app designed for testing load-balancing and demonstrating container concepts. It continuously calls an API endpoint to display basic system information without needing to refresh the page.

Quickstart

To download and run the latest tag from Docker Hub, simply run:

docker run -d -p 5000:5000 bcbrookman/buoy

A more complex example using multiple replicas and a container load-balancer like the one below can be run with docker stack deploy or docker-compose --compatibility up -d

---
version: "3.3"

services:
  traefik:
    image: "traefik:v2.5"
    container_name: "traefik"
    command:
      - "--log.level=DEBUG"
      - "--api.insecure=true"
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--entrypoints.web.address=:80"
    ports:
      - "8000:80"
      - "8080:8080"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock:ro"

  buoy:
    image: "bcbrookman/buoy"
    deploy:
      replicas: 3
    labels:
      - "traefik.enable=true"
      - "traefik.http.services.buoy.loadbalancer.server.port=5000"
      - "traefik.http.routers.buoy.rule=PathPrefix(`/`)"
      - "traefik.http.routers.buoy.entrypoints=web"
      - "traefik.http.routers.buoy.service=buoy"

This docker-compose file can also be found in examples/
