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'.

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	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.

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	0c6fe94cf4	cmd/k8s-operator: add matching family addresses to status This was added in `3451b89e5f`, but resulted in the v6 Tailscale address being added to status when when the forwarding only happened on the v4 address.

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
