mac實戰mesos

如果程序一直deploy說明一定有問題
mac安裝

brew install mesos
brew upgrade mesos

啓動zookeeper 啓動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

啓動slave(注意端口，如果marathon中用到80等端口，需要將ports範圍足夠大)

/usr/local/Cellar/mesos/1.4.1/sbin/mesos-slave --help  查看幫助
啓動第一個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];'   

啓動第二個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];'   

測試task

/usr/local/Cellar/mesos/1.4.1/bin/mesos-execute --master=localhost:5050 --name=hellomesos --command="echo 'hello,mesos'"

啓動marathon

sudo ./bin/start --http_port 8088 --master ${HOST_IP}:5050 --zk zk://${HOST_IP}:2181/marathon -h ${HOST_IP} 

測試marathon

Command

while [ true ] ; do echo 'Hello Marathon' ; sleep 5 ; done

從marathon中使用docker啓動nginx

{
  "type": "DOCKER",
  "volumes": [],
  "docker": {
    "image": "library/nginx",
    "network": "BRIDGE",
    "portMappings": [
      {
        "containerPort": 80,
        "hostPort": 0,
        "servicePort": 2000,
        "protocol": "tcp",
        "labels": {}
      }
    ],
    "privileged": false,
    "parameters": [],
    "forcePullImage": false
  }
}

使用docker inspect containerid，查看動態分配的hostport
ps:在container裏邊， 這個web服務運行的端口是8080（containerPort的值）。在container外，Marathon會分配一個隨機端口（hostPort設置是0）

marathon-lb安裝

採用bridge方式，host方式失敗，不明白問題在哪兒**********
