Joe Tsai	c25968e1c5	all: make use of ctxkey everywhere (#10846 ) Also perform minor cleanups on the ctxkey package itself. Provide guidance on when to use ctxkey.Key[T] over ctxkey.New. Also, allow for interface kinds because the value wrapping trick also happens to fix edge cases with interfaces in Go.

Irbe Krumina	d0492fdee5	cmd/k8s-operator: adds a tailscale IngressClass resource, prints warning if class not found. (#10823 ) * cmd/k8s-operator/deploy: deploy a Tailscale IngressClass resource. Some Ingress validating webhooks reject Ingresses with .spec.ingressClassName for which there is no matching IngressClass. Additionally, validate that the expected IngressClass is present, when parsing a tailscale `Ingress`. We currently do not utilize the IngressClass, however we might in the future at which point we might start requiring that the right class for this controller instance actually exists.

Irbe Krumina	5cc1bfe82d	cmd/k8s-operator: remove configuration knob for Connector (#10791 ) The configuration knob (that defaulted to Connector being disabled) was added largely because the Connector CRD had to be installed in a separate step. Now when the CRD has been added to both chart and static manifest, we can have it on by default. Updates tailscale/tailscale#10878 Signed-off-by: Irbe Krumina <irbe@tailscale.com>	11 months ago
Irbe Krumina	469af614b0	cmd/k8s-operator: fix base truncating for extra long Service names (#10825 ) cmd/k8s-operator: fix base truncating for extra long Service names StatefulSet names for ingress/egress proxies are calculated using Kubernetes name generator and the parent resource name as a base. The name generator also cuts the base, but has a higher max cap. This commit fixes a bug where, if we get a shortened base back from the generator, we cut off too little as the base that we have cut will be passed into the generator again, which will then itself cut less because the base is shorter- so we end up with a too long name again.

Irbe Krumina	05093ea7d9	cmd/k8s-operator,k8s-operator: allow the operator to deploy exit nodes via Connector custom resource (#10724 ) cmd/k8s-operator/deploy/crds,k8s-operator/apis/v1alpha1: allow to define an exit node via Connector CR. Make it possible to define an exit node to be deployed to a Kubernetes cluster via Connector Custom resource. Also changes to Connector API so that one Connector corresponds to one Tailnet node that can be either a subnet router or an exit node or both. The Kubernetes operator parses Connector custom resource and, if .spec.isExitNode is set, configures that Tailscale node deployed for that connector as an exit node.

Irbe Krumina	1a08ea5990	cmd/k8s-operator: operator can create subnetrouter (#9505 ) * k8s-operator,cmd/k8s-operator,Makefile,scripts,.github/workflows: add Connector kube CRD. Connector CRD allows users to configure the Tailscale Kubernetes operator to deploy a subnet router to expose cluster CIDRs or other CIDRs available from within the cluster to their tailnet. Also adds various CRD related machinery to generate CRD YAML, deep copy implementations etc. Engineers will now have to run 'make kube-generate-all` after changing kube files to ensure that all generated files are up to date. * cmd/k8s-operator,k8s-operator: reconcile Connector resources Reconcile Connector resources, create/delete subnetrouter resources in response to changes to Connector(s). Connector reconciler will not be started unless ENABLE_CONNECTOR env var is set to true. This means that users who don't want to use the alpha Connector custom resource don't have to install the Connector CRD to their cluster. For users who do want to use it the flow is: - install the CRD - install the operator (via Helm chart or using static manifests). For Helm users set .values.enableConnector to true, for static manifest users, set ENABLE_CONNECTOR to true in the static manifest.

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.

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.

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.

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	8dbb3b8bbe	cmd/k8s-operator: remove unused structs. Cleanup missed in #6718 . Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	53a9cc76c7	cmd/k8s-operator: rename main.go -> operator.go. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
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.

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
