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. Regenerate operator.yaml Signed-off-by: Irbe Krumina <irbe@tailscale.com>	9 months ago
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.

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.

Irbe Krumina	18ceb4e1f6	cmd/{containerboot,k8s-operator}: allow users to define tailnet egress target by FQDN (#10360 ) * cmd/containerboot: proxy traffic to tailnet target defined by FQDN Add a new Service annotation tailscale.com/tailnet-fqdn that users can use to specify a tailnet target for which an egress proxy should be deployed in the cluster.

Irbe Krumina	cac290da87	cmd/k8s-operator: users can configure firewall mode for kube operator proxies (#9769 ) * cmd/k8s-operator: users can configure operator to set firewall mode for proxies Users can now pass PROXY_FIREWALL_MODE={nftables,auto,iptables} to operator to make it create ingress/egress proxies with that firewall mode Also makes sure that if an invalid firewall mode gets configured, the operator will not start provisioning proxy resources, but will instead log an error and write an error event to the related Service.

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.

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.

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.
