Marathon說'資源不足'需要少於可用的任務

Question

我有一個可通過公共IP訪問的Mesos Master。

我有一個提供一些資源的奴隸。

我嘗試部署一個小應用程序，但馬拉松迴應

曾經展開爲：

      port: 5051 
     } 
     path: "/slave(1)" 
    } 
] 

我不明白爲什麼馬拉松說「資源不足」，因爲它似乎從日誌，有足夠的...

我解決了它通過添加resources=ports:[1-65000]代理執行命令：

/usr/sbin/mesos-slave --master=10.2.0.56:5050 --work_dir=/var/lib/mesos/agent --containerizers=docker --executor_registration_timeout=3mins --log_dir=/var/log/mesos --resources=ports:[1-65000] --advertise_ip=10.1.10.20 --advertise_port=5051
