Wei Wei commented on MESOS-6225:
--------------------------------

Thanks, I use sysctl -w net.ipv4.ip_local_reserved_ports="start end" reserve port range defined in mesos-agent resource files solved this problem.

> we implement a scheduler to launch a batch of data process worker in docker container, we use network: host and assign random picked port for the process worker and encounter a port collision problem:
> the port we choose for the container was taken by the mesos-docker-container.
> mesos-agent resource config:
> {"name":"ports","type":"RANGES","ranges":{"range": [{"begin":10000,"end":32000}]}}]
> root@xs35:lsof -i:31981
> COMMAND     PID USER   FD   TYPE    DEVICE SIZE/OFF NODE NAME
> mesos-doc  2835 root    8u  IPv4 433237650      0t0  TCP 10.34.38.30:31981 (LISTEN)
> the port was taken by mesos-docker-executor and the framework still offer port resource 31981
> is there a way to set mesos-docker-executors port range?
