Auto-mount non `/Users` directory on Docker Machine (docker/machine#1826)

profile

# This Gist contains a snippet for auto-mounting non `/Users` or `/c/Users` directory on docker-machine with VirtualBox driver.

# 1. Add more shared folder on VirtualBox e.g., D:\Code -> /d/Code (and make it permanent)
# 2. Access Docker Machine SSH `docker-machine ssh`
# 3. Append the following code after original `/var/lib/boot2docker/profile` file. (as root/sudo)
# 4. `docker-machine restart`
# Note: Change the last line to match your shared folder
try_mount_share() {
	dir="$1"

	mkdir -p "$dir" 2>/dev/null
	if ! mount -t vboxsf -o "$mountOptions" "$name" "$dir" 2>/dev/null; then
		rmdir "$dir" 2>/dev/null || true

			dir="$(dirname "$dir")"
			rmdir "$dir" 2>/dev/null || break
