Question

我尝试使用Docker在本地计算机上安装Mesos。我读了this tutorial并稍微改了一下，因为我使用的是Docker for Mac。我的想法是将动物园管理员，船长，马拉松和奴隶放入一个网络进行相互通信。

我拥有的主节点已经识别出奴隶（我在下面说明了一个图）但我的问题是一个简单的应用程序无法部署echo "hello" >> /tmp/1543Feb19.txt而Marathon一直在说实例0/1带黄灯

我检查了网络，检查这些容器是否可以通信，但看起来可以。但

                "IPv6Address": ""
            }
        },

这就是我跑马拉松的方式（172.18.0.2是Zookeeper的IP）

docker run -d -p 8080:8080 --net="my-tiny-cluster" \
--name="marathon" "garland/mesosphere-docker-marathon" \
--master zk://172.18.0.2:2181/mesos --zk zk://172.18.0.2:2181/marathon

我的问题是我错过了正常运行的东西？谢谢。
