检查mesos和marathon在浏览器中输入http://192.168.56.7:5050看到如下图，表示mesos安装成功
在浏览器中输入http://192.168.56.7:8080看到如下图，表示marathon安装成功
使用marathon调度mesos创建docker容器编辑json文件# vim nginx.json{"id":"nginx","cpus":0.1,"mem":10,"instances": 1,"constraints":[["hostname", "UNIQUE",""]],"container": { "type":"DOCKER", "docker": { "image": "nginx", "network": "BRIDGE", "portMappings": [ {"containerPort": 80,"hostPort": 0,"servicePort": 0, "protocol":"tcp" } ] }}}调用json# curl -X POSThttp://192.168.56.7:8080/v2/apps-d @nginx.json -H "Content-type:application/json"
查看mesos
查看marathon
使用docker查看# docker psCONTAINERID IMAGE COMMAND CREATED STATUS PORTS NAMES5df80cefaee8 nginx "nginx -g 'daemonoff" 6 minutes ago Up 6 minutes 443/tcp, 0.0.0.0:31125->80/tcpmesos-8a9358e1-275d-46ec-ba5c-e57e0578f354-S1.071c4b7a-55d0-41f6-9259-077373fb8e18
