Change hostname in docker container running chronos

[Jakub Veverka]

Hi, 

I am running chronos in docker conatiner and I am trying to change hosntame using --hostname switch. 

In the end I am getting following error: Error: Bad arguments for option 'hostname': '10.0.1.102 0dcbf74a80c3' - you should provide exactly one argument for this option

It smells like a bug to me, but its also possible I am doing something wrong. 

How I run container:

ip-10-0-1-180 ~ # docker run --rm -it -e LIBPROCESS_IP=`cat /etc/ip` -e IP=`cat /etc/ip` -p 8080:8080 -e LIBPROCESS_PORT=10001 -e ZOOKEEPER_ENDPOINTS=`/var/lib/scripts/get_zookeeper_endpoints.sh` quay.io/appuri/chronos /bin/bash

Show envs:

mesos@0dcbf74a80c3:/opt$ env

LIBPROCESS_IP=10.0.1.102

HOSTNAME=0dcbf74a80c3

TERM=xterm

ZOOKEEPER_ENDPOINTS=10.0.1.102:2181,10.0.1.100:2181,10.0.1.101:2181

Start chronos:

Chronos home set to /opt/chronos

curl: (22) The requested URL returned error: 404 Not Found

Using jar file: /opt/chronos/target/chronos-2.3.4.jar[0]

[scallop] Error: Bad arguments for option 'hostname': '10.0.1.102 0dcbf74a80c3' - you should provide exactly one argument for this option

Any thoughts on that?
