can't map mongo data directory of a window image in window host

[tungjb]

I got an error when map mongo data directory of a window image in window host

docker run -ti -p 27017:27017 -v c:/temp/mongo:c:/data dockermongo
docker: Error response from daemon: container c35916e043fe3607a2666ee7d0db66b78fb0164cea6d47c7aeab8e524edc0ea3 encountered an error during Start: failure in a Windows system call: The compute system exited unexpectedly. (0xc0370106).

This is the image that I used:
https://github.com/docker-library/mongo/blob/32e5645325ae5dff2ae6f934049cbd6b4635aec0/3.6/windows/windowsservercore-1709/Dockerfile

In the above link, there is a note about mapping issue. However, it seems like the issue has been fixed by virtualbox and also by mongo.

Any idea whether it is possible to map the data directory in window host?

If you're using Linux Containers on Windows(LCOW) there are contraindications related to NTFS and Docker's Overlay2 and AUFS

NTFS is still unsupported by Docker moby/moby#23930 (comment) however LCOW attempts to overcome this https://docs.microsoft.com/en-us/virtualization/windowscontainers/deploy-containers/linux-containers#Bind-mounts with Hyper-V POSIX translations and it seems you've run into an error where a Windows system call wasn't translated, so I would discern that mongo is unsupported for LCOW

You should still be able to let Docker manage your volume as a named volume, this is the alternative to a bind-mount: MariaDB/mariadb-docker#152 (comment)

Actually I skipped over your use of mongo:windowsservercore-1709 so my above comment is not very relevant.

There is an ongoing issue related to your error message on container start docker/for-win#676 and a comment in the thread notes that mounting the volume to a populated folder will give the error docker/for-win#676 (comment) but it seems this is if the volume is "baked into the image" so in a Dockerfile. Others in the thread mention getting this error from just simply mounting the volume in a docker-compose.yml, just the same as a docker run -v like your own usage

You're using the image dockermongo, is this a Dockerfile you've built?

Hi @wglambert, thanks for your answer. dockermongo is built using Dockerfile 3.6.8-windowsservercore-1709 without any changes. I try to create the mapping after that. So, I will need to check if it can work in a linux base image on linux.

This isn't really the appropriate place to file this -- this repository is for the documentation of the official images.

For help debugging your deployment/implementation/environment, I'd recommend trying the Docker Community Forums, the Docker Community Slack, or Stack Overflow.

Sure. Noted.
