You can use Tailscale with Kubernetes, you know

Tailscale has made significant strides in integrating with Kubernetes and container ecosystems, providing a managed Docker image that facilitates its deployment. This image is available on Docker Hub and GitHub Packages, allowing users to run Tailscale within containers without requiring traditional Linux capabilities like CAP_NET_RAW and CAP_NET_ADMIN, thanks to its userspace networking feature. With the release of Tailscale v1.16, additional features such as a built-in HTTP proxy server enhance its utility on platforms like Heroku and Google Cloud Run. Users can add containers as ephemeral nodes using authentication keys and manage these through Kubernetes secrets, enabling seamless integration with existing infrastructure. Tailscale can also function as a sidecar container, providing flexibility for deployments where security or vendor constraints exist. Furthermore, it acts as a proxy within Kubernetes clusters, facilitating secure workload sharing across networks using MagicDNS, thereby avoiding exposure on the public internet.
