1: First prepare a JSON file (Hello.json)

{

"id": "Hello",

"cmd": "Echo hello; Sleep 10 ",

"Mem": 16,

"CPUs": 0.1,

"Instances": 1,

"Disk": 0.0,

"Ports": [0]

}

3: Then invoke API to launch an app via marathon

Curl-i-H ' content-type:application/json ' [email protected] 172.16.7.12:8080/v2/apps

Then log in and Marathon to see that the process has started.

5: Complete JSON sample
