I'm not sure what other information I am to submit to debug this situation. Is there that can be done to improve performance?
回答1:
To speed this up you can also use http://docker-sync.io - it has been specifically build for this case under OSX.
回答2:
Mounting of home (mac) folders in VirtualBox is known to be extremely slow with data transfer. Try using Docker for Mac instead, or copy your content to a named volume. e.g.:
docker create volume --name myvol
docker run --rm --name data-container -v myvol:/data alpine top
docker cp dir/with/files data-container:/data
docker rm -f data-container
This gives you a volume myvol which you can mount on any container. The volume data is kept in the VirtualBox host.
