提供一种在Docker中更改或覆盖Zookeeper配置的方法

Question

我将docker与zookeeper一起使用，

COPY zookeeper-3.4.12.tar.gz /opt
RUN cd /opt && \
        tar -xvf zookeeper-3.4.12.tar.gz
ENV ZK_HOME /opt/zookeeper-3.4.12

zoo.cfg有很多配置，我想更改这些参数， zoo.cfg

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5

某些Docker实例更改syncLimit = 10，某些Docker实例更改tickTime = 1000 我应该使用ARG，通过docker run env传递这些参数吗？但是如何更改zoo.cfg内容？我不想docker exec -it dockerid并更改文件，然后提交。还有其他建议吗？
