+You can use `-v` to bind mount `conf` and `storage` to the hosts filesystem:
 ```bash
 V_PATH=/path/for/verdaccio; docker run -it --rm --name verdaccio -p 4873:4873 \
   -v $V_PATH/conf:/verdaccio/conf \

+>Note: Verdaccio runs as a non-root user (uid=101, gid=101) inside the container, if you use bind mount to override default, you need to make sure the mount directory is assigned to the right user. In above example, you need to run `sudo chown -R 101:101 /opt/verdaccio` otherwise you will get permission errors at runtime. [Use docker volume](https://docs.docker.com/storage/volumes/) is recommended over using bind mount.
