Getting started with Docker and Tailscale

In a guide by Alex Kretzschmar, the basics of installing Docker and connecting the first container with Tailscale are discussed, emphasizing the ease of integrating containers into a Tailscale network, referred to as a "tailnet." The video tutorial highlights the built-in feature for generating automated TLS certificates for nodes, simplifying network security without needing complex firewall rules or port forwarding. By placing containers directly onto a tailnet, each container becomes a full-fledged node, regardless of NAT setup challenges, aligning with Tailscale's mission to create small, trusted networks of devices and services. The guide suggests starting with the official Docker image and notes that Tailscale offers a free plan that supports up to 100 devices and three users, providing ample opportunity to explore and utilize Tailscale's capabilities.
