如果程序一直deploy说明一定有问题
mac安装
brew install mesos brew upgrade mesos
启动zookeeper 启动master
HOST_IP=100.80.128.98
sudo /usr/local/Cellar/mesos/1.4.1/sbin/mesos-master --ip=${HOST_IP} \
--log_dir=/Users/lifei/dockerproject/mesos/master/log --work_dir=/Users/lifei/dockerproject/mesos/master/work \
--ZK=zk://${HOST_IP}:2181/mesos --quorum=1启动slave(注意端口，如果marathon中用到80等端口，需要将ports范围足够大)
/usr/local/Cellar/mesos/1.4.1/sbin/mesos-slave --help 查看帮助
启动第一个slave
sudo /usr/local/Cellar/mesos/1.4.1/sbin/mesos-slave --master=${HOST_IP}:5050 \
--log_dir=/Users/lifei/dockerproject/mesos/slave/log --work_dir=/Users/lifei/dockerproject/mesos/slave/work \
--containerizers=docker,mesos --no-hostname_lookup --ip=${HOST_IP} --resources='ports:[1-32000];'
启动第二个slave
sudo /usr/local/Cellar/mesos/1.4.1/sbin/mesos-slave --master=${HOST_IP}:5050 \
--log_dir=/Users/lifei/dockerproject/mesos/slave/log2 --work_dir=/Users/lifei/dockerproject/mesos/slave/work2 \
--containerizers=docker,mesos --no-hostname_lookup --ip=${HOST_IP} --resources='ports:[1-32000];'测试task
/usr/local/Cellar/mesos/1.4.1/bin/mesos-execute --master=localhost:5050 --name=hellomesos --command="echo 'hello,mesos'"
启动marathon
sudo ./bin/start --http_port 8088 --master ${HOST_IP}:5050 --zk zk://${HOST_IP}:2181/marathon -h ${HOST_IP}测试marathon
Command while [ true ] ; do echo 'Hello Marathon' ; sleep 5 ; done
从marathon中使用docker启动nginx

使用docker inspect containerid，查看动态分配的hostport
ps:在container里边， 这个web服务运行的端口是8080（containerPort的值）。在container外，Marathon会分配一个随机端口（hostPort设置是0）marathon-lb安装
采用bridge方式，host方式失败，不明白问题在哪儿**********
