mesos 集羣功能測試
###############################################################
1：首先準備一個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：然後調用api，通過marathon啓動一個應用
curl -i -H 'Content-Type: application/json' [email protected] 172.16.7.12:8080/v2/apps
然後登陸,marathon 即可看到進程已經啓動。
5：完整json 樣例
