This commit contains the implementation of multi-tailnet support within the Kubernetes Operator
Each of our custom resources now expose the `spec.tailnet` field. This field is a string that must match the name of an existing `Tailnet` resource. A `Tailnet` resource looks like this:
```yaml
apiVersion: tailscale.com/v1alpha1
kind: Tailnet
metadata:
name: example # This is the name that must be referenced by other resources
spec:
credentials:
secretName: example-oauth
```
Each `Tailnet` references a `Secret` resource that contains a set of oauth credentials. This secret must be created in the same namespace as the operator:
```yaml
apiVersion: v1
kind: Secret
metadata:
name: example-oauth # This is the name that's referenced by the Tailnet resource.
namespace: tailscale
stringData:
client_id: "client-id"
client_secret: "client-secret"
```
When created, the operator performs a basic check that the oauth client has access to all required scopes. This is done using read actions on devices, keys & services. While this doesn't capture a missing "write" permission, it catches completely missing permissions. Once this check passes, the `Tailnet` moves into a ready state and can be referenced. Attempting to use a `Tailnet` in a non-ready state will stall the deployment of `Connector`s, `ProxyGroup`s and `Recorder`s until the `Tailnet` becomes ready.
The `spec.tailnet` field informs the operator that a `Connector`, `ProxyGroup`, or `Recorder` must be given an auth key generated using the specified oauth client. For backwards compatibility, the set of credentials the operator is configured with are considered the default. That is, where `spec.tailnet` is not set, the resource will be deployed in the same tailnet as the operator.

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 1.25. (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.
