Use dumb-init in Dockerfile; chown tracker directory to proper uid Use dumb-init so proceses started from Roundup get properly reaped if they exit after the Roundup server instance. Also chown the tracker mount directory to the specified uid/gid.

#! /bin/sh

tracker=$(ps -ef | sed -ne '/roundup-server/s/^.*\s\(\w*\)=.*$/\1/p')
wget -q -O /dev/null --no-verbose http://localhost:8080/$tracker/
