mesos 集群功能测试
###############################################################
1：首先准备一个json文件(hello.json)
{
"id": "hello",
"cmd": "echo hello; sleep 10",
"mem": 16,
"cpus": 0.1,
"instances": 1,
"disk": 0.0,
"ports": [0]
}
3：然后调用api，通过marathon启动一个应用
curl -i -H ‘Content-Type: application/json‘ [email protected] 172.16.7.12:8080/v2/apps
然后登陆,marathon 即可看到进程已经启动。
5：完整json 样例
