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	66471710f8	cmd/k8s-operator: truncate long StatefulSet name prefixes (#10343 ) Kubernetes can generate StatefulSet names that are too long and result in invalid Pod revision hash label values. Calculate whether a StatefulSet name generated for a Service or Ingress will be too long and if so, truncate it.

Irbe Krumina	ed1b935238	cmd/k8s-operator: allow to install operator via helm (#9920 ) Initial helm manifests. Updates tailscale/tailscale#9222 Signed-off-by: Irbe Krumina <irbe@tailscale.com> Co-authored-by: Maisem Ali <maisem@tailscale.com>	1 year ago
Irbe Krumina	e9956419f6	cmd/k8s-operator: allow cleanup of cluster resources for deleted devices (#9917 ) Users should delete proxies by deleting or modifying the k8s cluster resources that they used to tell the operator to create they proxy. With this flow, the tailscale operator will delete the associated device from the control. However, in some cases users might have already deleted the device from the control manually.

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	f53c3be07c	cmd/k8s-operator: use our own container image instead of busybox We already have sysctl in the `tailscale/tailscale` image, just use that. Updates #cleanup Signed-off-by: Maisem Ali <maisem@tailscale.com>	1 year ago
Maisem Ali	5f4d76c18c	cmd/k8s-operator: rename egress annotation It was tailscale.com/ts-tailnet-target-ip, which was pretty redundant. Change it to tailscale.com/tailnet-ip. Updates #502 Signed-off-by: Maisem Ali <maisem@tailscale.com>	1 year ago
Maisem Ali	794650fe50	cmd/k8s-operator: emit event if HTTPS is disabled on Tailnet Instead of confusing users, emit an event that explicitly tells the user that HTTPS is disabled on the tailnet and that ingress may not work until they enable it.

Irbe Krumina	fe709c81e5	cmd/k8s-operator,cmd/containerboot: add kube egress proxy (#9031 ) First part of work for the functionality that allows users to create an egress proxy to access Tailnet services from within Kubernetes cluster workloads. This PR allows creating an egress proxy that can access Tailscale services over HTTP only.

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. Fixes errors like ``` boot: 2023/08/29 01:03:53 failed to set serve config: sending serve config: updating config: writing ServeConfig to StateStore: Operation cannot be fulfilled on secrets "ts-webdav-kfrzv-0": the object has been modified; please apply your changes to the latest version and try again {"level":"error","ts":"2023-08-29T01:03:48Z","msg":"Reconciler error","controller":"ingress","controllerGroup":"networking.k8s.io","controllerKind":"Ingress","Ingress":{"name":"webdav","namespace":"default"},"namespace":"default","name":"webdav","reconcileID":"96f5cfed-7782-4834-9b75-b0950fd563ed","error":"failed to provision: failed to create or get API key secret: Operation cannot be fulfilled on secrets \"ts-webdav-kfrzv-0\": the object has been modified; please apply your changes to the latest version and try again","stacktrace":"sigs.k8s.io/controller-runtime/pkg/internal/controller.(Controller).reconcileHandler\n\tsigs.k8s.io/controller-runtime@v0.15.0/pkg/internal/controller/controller.go:324\nsigs.k8s.io/controller-runtime/pkg/internal/controller.(Controller).processNextWorkItem\n\tsigs.k8s.io/controller-runtime@v0.15.0/pkg/internal/controller/controller.go:265\nsigs.k8s.io/controller-runtime/pkg/internal/controller.(*Controller).Start.func2.2\n\tsigs.k8s.io/controller-runtime@v0.15.0/pkg/internal/controller/controller.go:226"} ``` Updates #502 Updates #7895 Signed-off-by: Maisem Ali <maisem@tailscale.com>	1 year ago

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.
