1.為何要將jenkins安裝到mesos叢集中

老的一套Jenkins使用的是固定Jenkins slave節點來構建任務，當構建任務多的時候，總是會出現排隊等待的現象。為了改善這種情況，在網上找到了Jenkins On Mesos的解決方案。Jenkins Master可以在構建時根據實際需要動態的向Mesos申請slave節點，並在構建完成的一段時間後將節點歸還給Mesos

2.如何安裝?

使用marathon webUI新建一個application,

應用程式的配置如下:

{
  "id": "/jenkinsmaster",
  "cmd": null,
  "cpus": 1,
  "mem": 600,
  "disk": 0,
  "instances": 1,
  "acceptedResourceRoles": [],
  "container": {

      "privileged": false
    },
    "volumes": [],
    "portMappings": [
      {

        "protocol": "tcp",
        "servicePort": 10002
      },
      {
        "containerPort": 31500,
        "hostPort
 
": 31500,
        "labels": {},
        "protocol": "tcp",
        "servicePort": 10003
      }
    ]
  },
  "env": {
    "JENKINS_SLAVE_AGENT_PORT": "31500"
  },
  "healthChecks": [
    {
      "gracePeriodSeconds": 300,

    }
  ],
  "labels": {
    "HAPROXY_GROUP": "external",
    "HAPROXY_0_VHOST": "jenkins.evan.com"
