Tom Proctor f421907c38 all-kube: create Tailscale Service for HA kube-apiserver ProxyGroup (#16572 ) Adds a new reconciler for ProxyGroups of type kube-apiserver that will provision a Tailscale Service for each replica to advertise. Adds two new condition types to the ProxyGroup, TailscaleServiceValid and TailscaleServiceConfigured, to post updates on the state of that reconciler in a way that's consistent with the service-pg reconciler. The created Tailscale Service name is configurable via a new ProxyGroup field spec.kubeAPISserver.ServiceName, which expects a string of the form "svc:<dns-label>". Lots of supporting changes were needed to implement this in a way that's consistent with other operator workflows, including: * Pulled containerboot's ensureServicesUnadvertised and certManager into kube/ libraries to be shared with k8s-proxy. Use those in k8s-proxy to aid Service cert sharing between replicas and graceful Service shutdown. * For certManager, add an initial wait to the cert loop to wait until the domain appears in the devices's netmap to avoid a guaranteed error on the first issue attempt when it's quick to start. * Made several methods in ingress-for-pg.go and svc-for-pg.go into functions to share with the new reconciler * Added a Resource struct to the owner refs stored in Tailscale Service annotations to be able to distinguish between Ingress- and ProxyGroup- based Services that need cleaning up in the Tailscale API. * Added a ListVIPServices method to the internal tailscale client to aid cleaning up orphaned Services * Support for reading config from a kube Secret, and partial support for config reloading, to prevent us having to force Pod restarts when config changes. * Fixed up the zap logger so it's possible to set debug log level.

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 1.23. (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 commit-messages.md (or skim git log) for our commit message style.
