Nginx Proxy

Works with Docker Compose v2.

Compose file

services:
  whoami:
    image: jwilder/whoami
    environment:
      - VIRTUAL_HOST=whoami.example.com

  nginx-proxy:
    image: nginxproxy/nginx-proxy
    ports:
      - "80:80"
    volumes:
      - /var/run/docker.sock:/tmp/docker.sock:ro

Mounting the Docker socket is a potential security risk. If the nginx-proxy container is compromised, an attacker could gain full control of the host. If you are concerned about this risk, consider using docker-socket-proxy to access the Docker socket from the nginx-proxy container.

Steps

1. Change domain in docker-compose.yml to a domain pointing to your server

2. Start all services

    docker-compose up -d
   

3. Change whoami image to, for example, traefik/whoami.

4. Deploy a new version of whoami service without downtime.

    docker rollout whoami
