在这里读书 docker-compose 文件：（来源：https://docs.traefik.io/user-guides/docker-compose/acme-dns/#setup)

version: "3.3"
services:
  traefik:
    image: "traefik:v2.1.0"
    container_name: "traefik"
    command:
      - "--log.level=DEBUG"

我该怎么设置 --log.level=DEBUG 此部署文件中的命令：

{
  "id": "/whoami",
  "cpus": 0.1,
  "mem": 256.0,
  "instances": 1,
  "container": {
    "type": "DOCKER",
    "docker": {
      "image": "traefik:v2.1.0",
      "network": "BRIDGE",
      "portMappings": [
        {
          "containerPort": 80,
          "protocol": "tcp"
        }
      ]
    }
  }
}
