I want to mount an external configuration file but it is invalid.

$ docker -v

@qingdujun try checking the container logs to see the reason of failure. I guess that's because your dataDir doesn't exist within the container.

Thanks, I found my mistake.

bash-4.4# vi conf/zoo.cfg

The right way

bash-4.4# vi /conf/zoo.cfg

Here are all my commands.

$ sudo docker exec -it macvlan_zk1 /bin/bash
bash-4.4# echo 1 >> /data/myid
bash-4.4# cat /data/myid
1
bash-4.4# vi /conf/zoo.cfg
bash-4.4# exit
exit
