zkimage=`docker images | grep zookeeper | awk {'print $1'}`
if [ -n "$zkimage" ]
then
    echo 'The zookeeper image is already existed.'
else
    echo 'Pull the latest zookeeper image.'
    docker pull zookeeper
fi

#Create network for zookeeper containers
zknet=`docker network ls | grep zknetwork | awk {'print $2'}`
if [ -n "$zknet" ]
then
    echo 'The zknetwork is already existed.'
else
    echo 'Create zknetwork.'
    docker network create zknetwork
