Irbe Krumina	c3e2b7347b	tailcfg,cmd/k8s-operator,kube: move Kubernetes cap to a location that can be shared with control (#12236) ... This PR is in prep of adding logic to control to be able to parse tailscale.com/cap/kubernetes grants in control: - moves the type definition of PeerCapabilityKubernetes cap to a location shared with control. - update the Kubernetes cap rule definition with fields for granting kubectl exec session recording capabilities. - adds a convenience function to produce tailcfg.RawMessage from an arbitrary cap rule and a test for it. An example grant defined via ACLs: "grants": [{ "src": ["tag:eng"], "dst": ["tag:k8s-operator"], "app": { "tailscale.com/cap/kubernetes": [{ "recorder": ["tag:my-recorder"] “enforceRecorder”: true }], }, } ] This grant enforces `kubectl exec` sessions from tailnet clients, matching `tag:eng` via API server proxy matching `tag:k8s-operator` to be recorded and recording to be sent to a tsrecorder instance, matching `tag:my-recorder`. The type needs to be shared with control because we want control to parse this cap and resolve tags to peer IPs.

Turn off stateful filtering for egress proxies to allow cluster traffic to be forwarded to tailnet. Allow configuring stateful filter via tailscaled config file. Deprecate EXPERIMENTAL_TS_CONFIGFILE_PATH env var and introduce a new TS_EXPERIMENTAL_VERSIONED_CONFIG env var that can be used to provide containerboot a directory that should contain one or more tailscaled config files named cap-<tailscaled-cap-version>.hujson. Containerboot will pick the one with the newest capability version that is not newer than its current capability version. Proxies with this change will not work with older Tailscale Kubernetes operator versions - users must ensure that the deployed operator is at the same version or newer (up to 4 version skew) than the proxies.

Irbe Krumina	19b31ac9a6	cmd/{k8s-operator,k8s-nameserver},k8s-operator: update nameserver config with records for ingress/egress proxies (#11019) ... cmd/k8s-operator: optionally update dnsrecords Configmap with DNS records for proxies. This commit adds functionality to automatically populate DNS records for the in-cluster ts.net nameserver to allow cluster workloads to resolve MagicDNS names associated with operator's proxies. The records are created as follows: * For tailscale Ingress proxies there will be a record mapping the MagicDNS name of the Ingress device and each proxy Pod's IP address. * For cluster egress proxies, configured via tailscale.com/tailnet-fqdn annotation, there will be a record for each proxy Pod, mapping the MagicDNS name of the exposed tailnet workload to the proxy Pod's IP. No records will be created for any other proxy types. Records will only be created if users have configured the operator to deploy an in-cluster ts.net nameserver by applying tailscale.com/v1alpha1.DNSConfig. It is user's responsibility to add the ts.net nameserver as a stub nameserver for ts.net DNS names. https://kubernetes.io/docs/tasks/administer-cluster/dns-custom-nameservers/#configuration-of-stub-domain-and-upstream-nameserver-using-coredns https://cloud.google.com/kubernetes-engine/docs/how-to/kube-dns#upstream_nameservers See also https://github.com/tailscale/tailscale/pull/11017 Updates tailscale/tailscale#10499 Signed-off-by: Irbe Krumina <irbe@tailscale.com>	7 months ago

Irbe Krumina	44aa809cb0	cmd/{k8s-nameserver,k8s-operator},k8s-operator: add a kube nameserver, make operator deploy it (#11919) ... * cmd/k8s-nameserver,k8s-operator: add a nameserver that can resolve ts.net DNS names in cluster. Adds a simple nameserver that can respond to A record queries for ts.net DNS names. It can respond to queries from in-memory records, populated from a ConfigMap mounted at /config. It dynamically updates its records as the ConfigMap contents changes. It will respond with NXDOMAIN to queries for any other record types (AAAA to be implemented in the future). It can respond to queries over UDP or TCP. It runs a miekg/dns DNS server with a single registered handler for ts.net domain names. Queries for other domain names will be refused. The intended use of this is: 1) to allow non-tailnet cluster workloads to talk to HTTPS tailnet services exposed via Tailscale operator egress over HTTPS 2) to allow non-tailnet cluster workloads to talk to workloads in the same cluster that have been exposed to tailnet over their MagicDNS names but on their cluster IPs. DNSConfig CRD can be used to configure the operator to deploy kube nameserver (./cmd/k8s-nameserver) to cluster.

Irbe Krumina	df8f40905b	cmd/k8s-operator,k8s-operator: optionally serve tailscaled metrics on Pod IP (#11699) ... Adds a new .spec.metrics field to ProxyClass to allow users to optionally serve client metrics (tailscaled --debug) on <Pod-IP>:9001. Metrics cannot currently be enabled for proxies that egress traffic to tailnet and for Ingress proxies with tailscale.com/experimental-forward-cluster-traffic-via-ingress annotation (because they currently forward all cluster traffic to their respective backends). The assumption is that users will want to have these metrics enabled continuously to be able to monitor proxy behaviour (as opposed to enabling them temporarily for debugging). Hence we expose them on Pod IP to make it easier to consume them i.e via Prometheus PodMonitor. Updates tailscale/tailscale#11292 Signed-off-by: Irbe Krumina <irbe@tailscale.com>	7 months ago

Irbe Krumina	3af0f526b8	cmd{containerboot,k8s-operator},util/linuxfw: support ExternalName Services (#11802) ... * cmd/containerboot,util/linuxfw: support proxy backends specified by DNS name Adds support for optionally configuring containerboot to proxy traffic to backends configured by passing TS_EXPERIMENTAL_DEST_DNS_NAME env var to containerboot. Containerboot will periodically (every 10 minutes) attempt to resolve the DNS name and ensure that all traffic sent to the node's tailnet IP gets forwarded to the resolved backend IP addresses. Currently: - if the firewall mode is iptables, traffic will be load balanced accross the backend IP addresses using round robin. There are no health checks for whether the IPs are reachable. - if the firewall mode is nftables traffic will only be forwarded to the first IP address in the list. This is to be improved. * cmd/k8s-operator: support ExternalName Services Adds support for exposing endpoints, accessible from within a cluster to the tailnet via DNS names using ExternalName Services. This can be done by annotating the ExternalName Service with tailscale.com/expose: "true" annotation. The operator will deploy a proxy configured to route tailnet traffic to the backend IPs that service.spec.externalName resolves to. The backend IPs must be reachable from the operator's namespace.

Irbe Krumina	bbe194c80d	cmd/k8s-operator: correctly determine cluster domain (#11512) ... Kubernetes cluster domain defaults to 'cluster.local', but can also be customized. We need to determine cluster domain to set up in-cluster forwarding to our egress proxies. This was previously hardcoded to 'cluster.local', so was the egress proxies were not usable in clusters with custom domains. This PR ensures that we attempt to determine the cluster domain by parsing /etc/resolv.conf. In case the cluster domain cannot be determined from /etc/resolv.conf, we fall back to 'cluster.local'.

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.
