Windows mounting /data/db

[Sebastien-Meiffren]

Hi,

I'm trying to mount /data/db from my Windows dev PC but everytime I try, Mongo crashes as it seems to not have the right BUT :

• I have changed the security parameters in windows to allow everyone to do everything (full access)
• If I mount in a different directory, it works (the container launchs itself and I can write in my directory)

Here are the logs :

I have files that have been created in my directory but they seems locked in. I have to turn off the docker-machine to delete WiredTiger.wt

+1, it can run ,but don't mount

[yosifkit]

Yeah I don't think it is possible to run mongodb using the shared folders of the virtual machine. You can still keep it persistent if you use -v /var/lib/boot2docker/my-mongodb-data/:/data/db/ which will store it on the VM hard disk.

[Sebastien-Meiffren]

That is unfortunate !
Any clues on why it is this way ?

[yosifkit]

Found a link: VirtualBox Shared Folders are not supported by mongodb.

I am having this issue on the latest Docker for Windows beta, which uses Hyper-v (not Virtualbox):

Is this expected? I thought Hyper-v resolved all problems posed by Virtualbox.

[yosifkit]

Docker for Windows does make much of the VM transparent to the Windows host, but it is still a virtual machine. I haven't tried using it with a mongo container, but I would guess that MongoDB needs something else supported by the file system. There is also this issue on the forums about volume mounts being extremely slow.

[ptitcoutu]

It works using a volume which is created using docker volume create --name=myvolume
The volume name is used instead of the local path. It's just a workaround.
To be more precise the line I used in my case :

docker volume create --name=mongodata
docker run -d -p 27017:27017 -v mongodata:/data/db --name=mymongo mongodb:3.3

[Oyelaking]

Wow!!!

@ptitcoutu thanks a lot. Been battling with this for over a week.

[christianulson]

on docker-machine i use this

conect to docker-machine
docker-machine ssh default

create a file
cd /

vi "/mnt/sda1/var/lib/boot2docker/bootlocal.sh"
inside of this file
mkdir -p <local_dir>
mount -t vboxsf -o defaults,uid=id -u docker,gid=id -g docker <mount_name> <local_dir>

exemple :

mkdir -p Projects
mount -t vboxsf -o defaults,uid=id -u docker,gid=id -g docker Projects Projects

Where Projects is the virtual box folder

To close and save the file:
:x

[Unthrottled]

@ptitcoutu Thanks! For those using compose you can do this:

version: '3'
services:
  mongodb:
    image: mongo:latest
    volumes:
      - mongodata:/data/db
volumes:
  mongodata:

[lsytj0413]

same issue here.

[davesmits]

I am running a local kubernetes cluster via Docker for Windows option. It there a way to get mongo working that way with a persistant storage?

[payneBrandon]

@davesmits were you able to get mongo working with your local kubernetes cluster? I've got the exact same scenario and just came upon this post...

[davesmits]

We solved it by using a volume inside the virtual machine

[renaudl]

Sames issue. Will try mounted volume but this should not be needed really

[erkansirin78]

I used relative path ./mongodb_node rather than C:/Users/myuser/mongodb_node added some data than restarted container. Data still there. But when I used fully path data was wiped out.

[vitalybrandes]

Have same problem. Is there any solution for that on do let for windows?
