我正在尝试将一堆服务部署到 docker for mac。让我事先说一下，将我的堆栈部署到一个真正的群体中非常有效。

我为 mac Beta 版本 17.05.0-ce-rc1-mac8 (16582) 运行 docker。我确实跑过swarm init它。

这是我的 yaml 文件：

version: "3"
services:
  proxy:
    image: traefik:1.2-alpine
    command: --web --docker --docker.swarmmode --docker.domain=docker.localhost --docker.watch --debug --logLevel=DEBUG \
             --entryPoints='Name:https Address::443 TLS' \
             --entryPoints='Name:http Address::80 Redirect.EntryPoint:https' \
             --acme=true \
             --acme.entryPoint=https \
             --acme.email=myemail@gmail.com \
             --acme.storage=/etc/traefik/acme/acme.json \
             --acme.domains=mydomain.com \
             --acme.ondemand=true \
             --acme.onhostrule=true
    networks:
      - proxy
    ports:
      - 80:80
      - 443:443
      - 8080:8080
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - traefikdata:/etc/traefik/acme
    deploy:
      placement:
        constraints:
          - node.labels.env == prod
          - node.role == manager
          - node.labels.traefik == yes

volumes:
  traefikdata:
    driver: local-persist
    driver_opts:
      mountpoint: ${MOUNTPOINT}/data/traefik

networks:
  proxy:
    driver: overlay

问题是，docker stack services proxy返回 REPLICAS 0/1。显然它在等待什么。docker service logs proxy_proxy什么都不返回。这是输出syslog -k Sender Docker：

我不知道这是否正常，图像已正确下载。

现在，我该如何解决正在发生的事情？顺便说一句：我确实应用了所有必要的标签，这是输出docker inspect moby：

另外，我在另一个容器中使用本地持久驱动程序。

查找服务的任务状态proxy。它会告诉你为什么服务底层的任务失败，这应该解释为什么你的服务永远不会达到超过 0/1 的副本。

您可以使用 找到特定服务的任务docker service ps $SERVICE_NAME。或者，堆栈服务的所有任务都使用docker stack ps $STACK_NAME.

无论哪种情况，从第一列中选​​择任务 ID，然后用于docker inspect $TASK_ID获取任务详细信息。该Status部分可能会说除 之外running的其他内容State，以及 . 的错误Message。
