docker 運行fastdfs 報錯

docker run -dti --network=host --name tracker -v /var/fdfs/tracker:/var/fdfs delron/fastdfs tracker

運行tracke時候報錯，
docker: Error response from daemon: Mounts denied:
The path /var/fdfs/tracker
is not shared from OS X and is not known to Docker.
You can configure shared paths from Docker -> Preferences… -> File Sharing.
See https://docs.docker.com/docker-for-mac/osxfs/#namespaces for more info

改一下需要
這估計是mac 上 docker一個小bug

docker run -dti --network=host --name tracker -v  ${HOME}/docker/fdfs/tracker:/var/fdfs delron/fastdfs tracker
