如何在opensuse中的同一台机器上的VM和docker之间共享目录？

Question

I know how to have a shared directory between docker and host and even VM and host, is there a way to directly share a directory between VM and the Docker in OpenSUSE, I am using virtual machine manager for the VM. please help.

Answer 1

Finally found the answer assign a tag to the VM filesystem(add file system from the "add hardware" option provided in the VM assign a string to it ie TAGNAME)

use the command inside the VM:

sudo mount -t 9p -o trans=virtio,version=9p2000.L,rw TAGNAME /MOUNT_POINT

And to make this directory permanently appear after every boot, edit the /etc/fstab , add this line at the end.

TAG   /MOUNT_POINT    9p  trans=virtio,version=9p2000.L,rw    0   0

To make the folder available from docker just use the -v option during docker creation and specify the same folder as source. This solves the problem. :)

Answer 2

The bind mount (-v or --mount) should apply within a VM as it does from a Host, in order to share a folder to your Docker container.

I do that all the time between a KVM and Docker container on SLES 12SP3 (not OpenSuse, but close)
