upsnap-docker-example

Example of a docker compose file and Serve configuration for UpSnap that adds Tailscale connectivity as a "sidecar." Created as part of the blog post: Make a dedicated Wake-on-LAN server with Tailscale.

See our blog post on Docker or YouTube video guide for more details and examples on configuring Tailscale inside containers.

To utilize this:

1. Create a folder on the hosting system named upsnap
2. Place compose.yaml inside the upsnap folder
3. Create a sub-folder inside upsnap, named ts-upsnap
4. Inside ts-upsnap, create folders state and config
5. If you want to access UpSnap from a single URL with no port number, as its own Tailscale node, place upsnap.json inside the config folder.

With those pieces in place, from the upsnap folder, run: docker compose up -d

This should pull and start the container images for UpSnap and Tailscale, and (if you set it up) use upsnap.json to configure your container with Tailscale serve.

To check for Tailscale errors and issues, run: docker exec -it ts-upsnap tailscale status
