There are several ways the filesystem of the host machine can be made available to containers.
By default, Docker does a bind-mount to a path on the host machine.
See Mount a host directory as a data volume in the official Docker docs for a better understanding of how this works.
Docksal uses the bind-mount approach as well. From the perspective of a container a local Linux path is mounted regardless of the host OS. That's because on macOS and Windows there's always a Linux VM and inside of the VM the host's (macOS/Win) filesystem is mounted.
On macOS the host filesystem is mounted using NFS, on Windows - using SMB.
/Users is configured as an NFS export by default and mounted into
/Users in the VM. This export can only
be accessed by the Docksal VM and the host itself.
When you have other software, like Vagrant, defining NFS exports, there may be conflicts, as NFS exports cannot overlap.
In such cases the default NFS export can be overridden via the
DOCKSAL_NFS_PATH variable in
When the VM is started fin will detect NFS export conflicts and suggest an automatic fix.

On Windows Docksal sets up shares for all logical drives. These shares can be only accessed by the current Windows user.
