Irbe Krumina	95dcc1745b	cmd/k8s-operator: reconcile tailscale Ingresses when their backend Services change. (#11255) ... This is so that if a backend Service gets created after the Ingress, it gets picked up by the operator.

Irbe Krumina	303125d96d	cmd/k8s-operator: configure all proxies with declarative config (#11238) ... Containerboot container created for operator's ingress and egress proxies are now always configured by passing a configfile to tailscaled (tailscaled --config <configfile-path>. It does not run 'tailscale set' or 'tailscale up'. Upgrading existing setups to this version as well as downgrading existing setups at this version works.

Irbe Krumina	5bd19fd3e3	cmd/k8s-operator,k8s-operator: proxy configuration mechanism via a new ProxyClass custom resource (#11074) ... * cmd/k8s-operator,k8s-operator: introduce proxy configuration mechanism via ProxyClass custom resource. ProxyClass custom resource can be used to specify customizations for the proxy resources created by the operator. Add a reconciler that validates ProxyClass resources and sets a Ready condition to True or False with a corresponding reason and message. This is required because some fields (labels and annotations) require complex validations that cannot be performed at custom resource apply time. Reconcilers that use the ProxyClass to configure proxy resources are expected to verify that the ProxyClass is Ready and not proceed with resource creation if configuration from a ProxyClass that is not yet Ready is required. If a tailscale ingress/egress Service is annotated with a tailscale.com/proxy-class annotation, look up the corresponding ProxyClass and, if it is Ready, apply the configuration from the ProxyClass to the proxy's StatefulSet. If a tailscale Ingress has a tailscale.com/proxy-class annotation and the referenced ProxyClass custom resource is available and Ready, apply configuration from the ProxyClass to the proxy resources that will be created for the Ingress. Add a new .proxyClass field to the Connector spec. If connector.spec.proxyClass is set to a ProxyClass that is available and Ready, apply configuration from the ProxyClass to the proxy resources created for the Connector. Ensure that when Helm chart is packaged, the ProxyClass yaml is added to chart templates. Ensure that static manifest generator adds ProxyClass yaml to operator.yaml.

Irbe Krumina	a6cc2fdc3e	cmd/{containerboot,k8s-operator/deploy/manifests}: optionally allow proxying cluster traffic to a cluster target via ingress proxy (#11036) ... * cmd/containerboot,cmd/k8s-operator/deploy/manifests: optionally forward cluster traffic via ingress proxy. If a tailscale Ingress has tailscale.com/experimental-forward-cluster-traffic-via-ingress annotation, configure the associated ingress proxy to have its tailscale serve proxy to listen on Pod's IP address. This ensures that cluster traffic too can be forwarded via this proxy to the ingress backend(s). In containerboot, if EXPERIMENTAL_PROXY_CLUSTER_TRAFFIC_VIA_INGRESS is set to true and the node is Kubernetes operator ingress proxy configured via Ingress, make sure that traffic from within the cluster can be proxied to the ingress target.

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	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.

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.
