Work in progress - Though the dockerfile builds and runs fine at its current state

This Dockerfile is your ticket to building a docker image for Uptime Kuma with Tailscale support; Uptime Kuma is a self-hosted monitoring tool, and Tailscale is a zero config VPN, making this combination a pretty useful one.

The Dockerfile provided always fetches the latest version of each image during the build, I'm still working on pinning a working version. (fallback for when the "latest" build fails)

1. Clone the Repository

Grab this repository by running:

git clone https://github.com/SGprooo/Uptime-Kuma-Tailscale-Docker.git

2. Build the Docker Image

Navigate to the directory with the Dockerfile and start the build:

docker build -t uptime-kuma-tailscale-docker .

3. Fire Up the Docker Container

Launch the Docker container with this command:

docker run -d --restart=always -p 3001:3001 --device /dev/net/tun:/dev/net/tun --cap-add=NET_ADMIN -v uptime-kuma:/app/data --name uptime-kuma -e TSKEY=YOUR_TAILSACLE_API_KEY -e TS_HOSTNAME=YOUR_HOSTNAME uptime-kuma-tailscale

Replace YOUR_TAILSACLE_API_KEY and YOUR_HOSTNAME with your Tailscale API key and desired hostname respectively. The hostname defaults to TailscaleUptimeKuma if not specified. You can generate a API key here.

Environment Variables

• TSKEY: Your Tailscale API key.
• TS_HOSTNAME: The hostname for your Tailscale node. Defaults to TailscaleUptimeKuma.

Volumes

• /app/data: This is where Uptime Kuma stores its data.

Exposed Ports

• Uptime Kuma's web interface is accessible at port 3001. If you need to map this port elsewhere, use -p 3002:3001 in your docker run command. (You can also access this web interface from other devices on the same Tailent)

This Dockerfile was revised from a dockerfile in discussion under this issue. As of the time of writing this, the build works fine with Tailscale 1.40.1 and Uptime Kuma 1.21.3. If you have any improvements, feel free to create a pull requests.

And heads up, I'm still figuring out how to integrate Tailscale ping with Uptime Kuma instead of using its default ICMP pings. I'll pull Uptime Kuma in the future.
