使用marathon部署一个dockerregister的教程

使用marathon部署一个docker register的教程

1.要求：

  成功部署一个docker register
  暂时还不能实现重启容器数据不丢,如果要保障重启容器数据不丢失，那就要使用volume进行外部存储。

2.实现：

cat marathon.json


{
  "id": "/bigdata-base-services/registry",
  "cpus": 1,
  "mem": 256,
  "disk": 0,
  "instances": 1,
  "container": {
    "type": "DOCKER",
    "docker": {
      "image": "registry",
      "network": "BRIDGE",
      "portMappings": [
        {
          "containerPort": 5000,
          "hostPort": 5000,
          "servicePort": 0,
          "protocol": "tcp",
          "name": "http",
          "labels": {}
        }
      ],
      "privileged": false,
      "parameters": [],
      "forcePullImage": false
    },
    "volumes": [
      {
        "containerPath": "/tmp/registry ",
        "hostPath": "/cloudstar/data/registry",
        "mode": "RW"
      }
    ]
  },
  "healthChecks": [
    {
      "gracePeriodSeconds": 300,
      "intervalSeconds": 60,
      "timeoutSeconds": 20,
      "maxConsecutiveFailures": 3,
      "portIndex": 0,
      "path": "/",
      "protocol": "HTTP",
      "ignoreHttp1xx": false
    }
  ],
  "upgradeStrategy": {
    "minimumHealthCapacity": 0,
    "maximumOverCapacity": 0
  },
  "constraints": [
    [
      "hostname",
      "CLUSTER",
      "bigdata03"
    ]
  ]
}

3.测试：

 通过marathon提供的端口能访问仓库内容
 https://bigdata03:31000/v2/_catalog

4.说明：

1.想通过marathon+meso实现微服务，也想管理器docker-register，这样全部微服务相关的容器都能用marathon管理起来。
2.通过这个测试为后续微服务做好知识探索
