The used Zookeeper image doesn't work.

[cd1989]

Entrypoint /usr/local/bin/zookeeperStart.sh of pravega/zookeeper:0.2.5 has following logic:

if [[ "$WRITE_CONFIGURATION" == true ]]; then
  . . .
  else
    echo Writing configuration gleaned from zookeeper ensemble
    echo "$CONFIG" | grep -v "^version="> $DYNCONFIG
  fi
fi

But $CONFIG is not set.

After changed to following, it works:

if [[ "$WRITE_CONFIGURATION" == true ]]; then
  . . .
  else
    echo Writing configuration gleaned from zookeeper ensemble
    java -jar /root/zu.jar get-all ${DOMAIN}:${CLIENT_PORT} | grep -v "^version=" > $DYNCONFIG
  fi
fi
