Irbe Krumina 3af0f526b8 cmd{containerboot,k8s-operator},util/linuxfw: support ExternalName Services (#11802 ) * cmd/containerboot,util/linuxfw: support proxy backends specified by DNS name Adds support for optionally configuring containerboot to proxy traffic to backends configured by passing TS_EXPERIMENTAL_DEST_DNS_NAME env var to containerboot. Containerboot will periodically (every 10 minutes) attempt to resolve the DNS name and ensure that all traffic sent to the node's tailnet IP gets forwarded to the resolved backend IP addresses. Currently: - if the firewall mode is iptables, traffic will be load balanced accross the backend IP addresses using round robin. There are no health checks for whether the IPs are reachable. - if the firewall mode is nftables traffic will only be forwarded to the first IP address in the list. This is to be improved. * cmd/k8s-operator: support ExternalName Services Adds support for exposing endpoints, accessible from within a cluster to the tailnet via DNS names using ExternalName Services. This can be done by annotating the ExternalName Service with tailscale.com/expose: "true" annotation. The operator will deploy a proxy configured to route tailnet traffic to the backend IPs that service.spec.externalName resolves to. The backend IPs must be reachable from the operator's namespace.

Tailscale

Private WireGuard® networks made easy

Overview

This repository contains the majority of Tailscale's open source code. Notably, it includes the tailscaled daemon and the tailscale CLI tool. The tailscaled daemon runs on Linux, Windows, macOS, and to varying degrees on FreeBSD and OpenBSD. The Tailscale iOS and Android apps use this repo's code, but this repo doesn't contain the mobile GUI code.

Other Tailscale repos of note:

the Android app is at https://github.com/tailscale/tailscale-android
the Synology package is at https://github.com/tailscale/tailscale-synology
the QNAP package is at https://github.com/tailscale/tailscale-qpkg
the Chocolatey packaging is at https://github.com/tailscale/tailscale-chocolatey

For background on which parts of Tailscale are open source and why, see https://tailscale.com/opensource/.

Using

We serve packages for a variety of distros and platforms at https://pkgs.tailscale.com.

Other clients

The macOS, iOS, and Windows clients use the code in this repository but additionally include small GUI wrappers. The GUI wrappers on non-open source platforms are themselves not open source.

Building

We always require the latest Go release, currently Go 1.22. (While we build releases with our Go fork, its use is not required.)

go install tailscale.com/cmd/tailscale{,d}

If you're packaging Tailscale for distribution, use build_dist.sh instead, to burn commit IDs and version info into the binaries:

./build_dist.sh tailscale.com/cmd/tailscale
./build_dist.sh tailscale.com/cmd/tailscaled

If your distro has conventions that preclude the use of build_dist.sh, please do the equivalent of what it does in your distro's way, so that bug reports contain useful version information.

Bugs

Please file any issues about this code or the hosted service on the issue tracker.

Contributing

PRs welcome! But please file bugs. Commit messages should reference bugs.

We require Developer Certificate of Origin Signed-off-by lines in commits.

See git log for our commit message style. It's basically the same as Go's style.
