Launch Traefik With the Docker Provider

Create a docker-compose.yml file where you will define a reverse-proxy service that uses the official Traefik image:

version: '3'

services:
  reverse-proxy:
    # The official v2 Traefik docker image
    image: traefik:v2.11
    # Enables the web UI and tells Traefik to listen to docker
    command: --api.insecure=true --providers.docker
    ports:
      # The HTTP port
      - "80:80"
      # The Web UI (enabled by --api.insecure=true)
      - "8080:8080"
    volumes:
      # So that Traefik can listen to the Docker events
      - /var/run/docker.sock:/var/run/docker.sock

Start your reverse-proxy with the following command:

docker-compose up -d reverse-proxy

V2版本的compose命令为：

docker compose up -d reverse-proxy
