Please read all the steps first before proceeding.

Steps

  1. Get ubuntu 18.04 LTS. Create a VM if needed.
  2. Install Tizen Studio from here: https://developer.tizen.org/development/tizen-studio/download

This is a living document. Everything in this document is made in good faith of being accurate, but like I just said; we don't yet know everything about what's going on.

Update: I've disabled comments as of 2025-01-26 to avoid everyone having notifications for something a year on if someone wants to suggest a correction. Folks are free to email to suggest corrections still, of course.

How to set up headscale with SWAG in docker-compose

Overview

This document descrives the process of setting up headscale with swag, using letsencrypt certs.

This assumes you have a subdomain (e.g. wg.example.com) pointing to your SWAG instance and want to use it as a reverse proxy.

Swag .env

Add the subdomain for your desired headscale domain to your .env file.

For example: SWAG_EXTRA_DOMAINS=wg.example.com

Change docker's default /var/lib/docker to different directory on Ubuntu
1. Take a backup of docker.service file.
$ cp /lib/systemd/system/docker.service /lib/systemd/system/docker.service.orig
2. Modify /lib/systemd/system/docker.service to tell docker to use our own directory
instead of default /var/lib/docker. In this example, I am using /p/var/lib/docker
Apply below patch.
$ diff -uP -N /lib/systemd/system/docker.service.orig /lib/systemd/system/docker.service
--- /lib/systemd/system/docker.service.orig 2018-12-05 21:24:20.544852391 -0800
