Tom Proctor	3099323976	cmd/k8s-operator,k8s-operator,go.{mod,sum}: publish proxy status condition for annotated services (#12463) ... Adds a new TailscaleProxyReady condition type for use in corev1.Service conditions. Also switch our CRDs to use metav1.Condition instead of ConnectorCondition. The Go structs are seralized identically, but it updates some descriptions and validation rules. Update k8s controller-tools and controller-runtime deps to fix the documentation generation for metav1.Condition so that it excludes comments and TODOs. Stop expecting the fake client to populate TypeMeta in tests. See kubernetes-sigs/controller-runtime#2633 for details of the change. Finally, make some minor improvements to validation for service hostnames.

Irbe Krumina	807934f00c	cmd/k8s-operator,k8s-operator: allow proxies accept advertized routes. (#12388) ... Add a new .spec.tailscale.acceptRoutes field to ProxyClass, that can be optionally set to true for the proxies to accept routes advertized by other nodes on tailnet (equivalent of setting --accept-routes to true).

Tom Proctor	23e26e589f	cmd/k8s-operator,k8s-opeerator: include Connector's MagicDNS name and tailnet IPs in status (#12359) ... Add new fields TailnetIPs and Hostname to Connector Status. These contain the addresses of the Tailscale node that the operator created for the Connector to aid debugging. Fixes #12214 Signed-off-by: Tom Proctor <tomhjp@users.noreply.github.com>	6 months ago
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	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.
