Maisem Ali	c919ff540f	cmd/k8s-operator,ipn/store/kubestore: patch secrets instead of updating We would call Update on the secret, but that was racey and would occasionaly fail. Instead use patch whenever we can.

Maisem Ali	0c6fe94cf4	cmd/k8s-operator: add matching family addresses to status This was added in `3451b89e5f`, but resulted in the v6 Tailscale address being added to status when when the forwarding only happened on the v4 address.

Maisem Ali	c8dea67cbf	cmd/k8s-operator: add support for Ingress resources Previously, the operator would only monitor Services and create a Tailscale StatefulSet which acted as a L3 proxy which proxied traffic inbound to the Tailscale IP onto the services ClusterIP. This extends that functionality to also monitor Ingress resources where the `ingressClassName=tailscale` and similarly creates a Tailscale StatefulSet, acting as a L7 proxy instead. Users can override the desired hostname by setting: ``` - tls hosts: - "foo" ``` Hostnames specified under `rules` are ignored as we only create a single host. This is emitted as an event for users to see. Fixes #7895 Signed-off-by: Maisem Ali <maisem@tailscale.com>	1 year ago
Maisem Ali	12ac672542	cmd/k8s-operator: handle changes to services w/o teardown Previously users would have to unexpose/expose the service in order to change Hostname/TargetIP.

Maisem Ali	24509f8b22	cmd/k8s-operator: add support for control plane assigned groups Previously we would use the Impersonate-Group header to pass through tags to the k8s api server. However, we would do nothing for non-tagged nodes. Now that we have a way to specify these via peerCaps respect those and send down groups for non-tagged nodes as well. For tagged nodes, it defaults to sending down the tags as groups to retain legacy behavior if there are no caps set. Otherwise, the tags are omitted.

Brad Fitzpatrick	4664318be2	client/tailscale: revert CreateKey API change, add Client.CreateKeyWithExpiry The client/tailscale is a stable-ish API we try not to break. Revert the Client.CreateKey method as it was and add a new CreateKeyWithExpiry method to do the new thing. And document the expiry field and enforce that the time.Duration can't be between in range greater than 0 and less than a second.

Vince Prignano	30380403d0	cmd/k8s-operator: remove use of InjectClient (deprecated) The dependency injection functionality has been deprecated a while back and it'll be removed in the 0.15 release of Controller Runtime.

David Anderson	8171eb600c	cmd/k8s-operator: move the operator into its own namespace. The operator creates a fair bit of internal cluster state to manage proxying, dumping it all in the default namespace is handy for development but rude for production.

David Anderson	3a5fc233aa	cmd/k8s-operator: use oauth credentials for API access. This automates both the operator's initial login, and provisioning/deprovisioning of proxies. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	a7ab3429b6	cmd/k8s-operator: refactor reconcile loop, un-plumbing reconcile.Result. We used to need to do timed requeues in a few places in the reconcile logic, and the easiest way to do that was to plumb reconcile.Result return values around. But now we're purely event-driven, so the only thing we care about is whether or not an error occurred. Incidentally also fix a very minor bug where headless services would get completely ignored, rather than reconciled into the correct state. This shouldn't matter in practice because you can't transition from a headful to a headless service without a deletion, but for consistency let's avoid having a path that takes no definite action if a service of interest does exist. Updates #502. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	835a73cc1f	cmd/k8s-operator: remove unnecessary timed requeue. Previously, we had to do blind timed requeues while waiting for the tailscale hostname, because we looked up the hostname through the API. But now the proxy container image writes back its hostname to the k8s secret, so we get an event-triggered reconcile automatically when the time is right. Updates #502 Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	d857fd00b3	cmd/k8s-operator: sprinkle debug logging throughout. As is convention in the k8s world, use zap for structured logging. For development, OPERATOR_LOGGING=dev switches to a more human-readable output than JSON. Updates #502 Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	8ccd707218	cmd/k8s-operator: remove times requeues in proxy deletion path. Our reconcile loop gets triggered again when the StatefulSet object finally disappears (in addition to when its deletion starts, as indicated by DeletionTimestamp != 0). So, we don't need to queue additional reconciliations to proceed with the remainder of the cleanup, that happens organically. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	9c77205ba1	cmd/k8s-operator: add more tests for "normal" paths. Tests cover configuring a proxy through an annotation rather than a LoadBalancerClass, and converting between those two modes at runtime. Updates #502. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	c902190e67	cmd/k8s-operator: factor out some of the larger expected test outputs. For other test cases, the operator is going to produce similar generated objects in several codepaths, and those objects are large. Move them out to helpers so that the main test code stays a bit more intelligible. The top-level Service that we start and end with remains in the main test body, because its shape at the start and end is one of the main things that varies a lot between test cases. Updates #502.

David Anderson	bc8f5a7734	cmd/k8s-operator: add a basic unit test. The test verifies one of the successful reconcile paths, where a client requests an exposed service via a LoadBalancer class. Updates #502. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	3b7ae39a06	cmd/k8s-operator: use the client's authkey method to create auth keys. Also introduces an intermediary interface for the tailscale client, in preparation for operator tests that fake out the Tailscale API interaction. Updates #502. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	b2d4abf25a	cmd/k8s-operator: add a kubernetes operator. This was initially developed in a separate repo, but for build/release reasons and because go module management limits the damage of importing k8s things now, moving it into this repo. At time of commit, the operator enables exposing services over tailscale, with the 'tailscale' loadBalancerClass. It also currently requires an unreleased feature to access the Tailscale API, so is not usable yet. Updates #502. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
