Tailscale Nginx TLS

This project serves as a study project to learn how to configure an Nginx instance inside Docker that is exposed through a Tailscale tailnet with a TLS certificate generated by Tailscale. The setup demonstrates how to:

• Run Nginx in a Docker container
• Connect the container to Tailscale
• Generate and use Tailscale TLS certificates
• Configure Nginx to serve content securely

Prerequisites

• Docker installed
• Tailscale account and CLI
• Basic understanding of Docker and Nginx configuration

Setup Instructions

1. Clone this repository:

   git clone https://github.com/EduardoThums/tailscale-nginx-tls.git
   cd tailscale-nginx-tls

2. Generate the TLS certificate on tailscale

   cd certificates
   tailscale cert your-domain.ts.net

3. Build and start the Docker container:

   TAILSCALE_HOSTNAME=your-domain.ts.net docker compose up -d

4. Verify the container is running:

   docker ps

5. Access your Nginx server through the Tailscale network using the hostname you configured.

   curl https://your-domain.ts.net
