Docker install

[nguy]

I followed the docker install instructions on the new website. To allow Hawkeye to run with lrose -- HawkEye -f ~/data/nexrad/20180515/* I had to do two things to avoid the following error

xhost:  bad hostname "3(NXDOMAIN)"
QXcbConnection: Could not connect to display 3(NXDOMAIN):0

I had to do the following, which might be useful for install instructions.

1. Start XQuartz and ensure that Allow connections from network Clients was selected (close and restart to enable)
2. A modification for obtaining the IP address of my machine [I am running MacOS 10.13.6] beginning at Line 93. I commented out the lines replaced.

# Common docker options

my_os=`uname`
case $my_os in
    Linux)
	DISPLAY_OPT="--env=DISPLAY --env QT_X11_NO_MITSHM=1"
	;;
    Darwin)
	my_host=`hostname`
#	my_ip=`host $my_host`
#	my_ip=${my_ip##* }
	my_ip=$(ifconfig en0 | grep inet | awk '$1=="inet" {print $2}')
	DISPLAY_OPT="-e DISPLAY=$my_ip:0"
	xhost +$my_ip > /dev/null
    ;;
    *)
	echo "Unknown OS '$my_os'. I don't know how to set up DISPLAY. Using Linux"
	DISPLAY_OPT="--env=\"DISPLAY\" --env QT_X11_NO_MITSHM=1"
	;;
esac

Thank you! I added your fix for my_ip to the lrose script in release-tools/elle/lrose-docker-scripts.
