# This script allows you to easily add a container to your Tailscale network
|
|
# to share the connection with others without opening a port.
|
|
#
|
|
# To utilize this script just put this script somewhere on your unRAID
|
|
# Server (eg: /mnt/user/appdata/scripts/tailscale.sh is preferred) and make
|
|
# sure it is executable `chmod +x tailscale.sh`.
|
|
# After that edit the template from the container that you want to add to
|
|
# your Tailscale network and do the following:
|
|
#
|
|
# Add the following variables:
|
|
# Key: TAILSCALE_KEY
|
|
# Value: <Key generated by Tailscale for the container>
|
|
#
|
|
# Key: TAILSCALE_HOSTNAME
|
|
# Value: <Your preferred hostname for the container>
|
|
#
|
|
# Finally mount the script to the container in the template:
|
|
# Container Path: /opt/scripts/user.sh
|
|
# Host Path: /mnt/user/appdata/scripts/tailscale.sh
|
|
#
|
|
# The script will then add the container to your Tailscale network.
