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>	6 months ago
Lee Briggs	14ac41febc	cmd/k8s-operator,k8s-operator: proxyclass affinity (#11862 ) add ability to set affinity rules to proxyclass Updates#11861 Signed-off-by: Lee Briggs <lee@leebriggs.co.uk>	6 months ago
Irbe Krumina	38fb23f120	cmd/k8s-operator,k8s-operator: allow users to configure proxy env vars via ProxyClass (#11743 ) Adds new ProxyClass.spec.statefulSet.pod.{tailscaleContainer,tailscaleInitContainer}.Env field that allow users to provide key, value pairs that will be set as env vars for the respective containers. Allow overriding all containerboot env vars, but warn that this is not supported and might break (in docs + a warning when validating ProxyClass).

Irbe Krumina	303125d96d	cmd/k8s-operator: configure all proxies with declarative config (#11238 ) Containerboot container created for operator's ingress and egress proxies are now always configured by passing a configfile to tailscaled (tailscaled --config <configfile-path>. It does not run 'tailscale set' or 'tailscale up'. Upgrading existing setups to this version as well as downgrading existing setups at this version works.

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	469af614b0	cmd/k8s-operator: fix base truncating for extra long Service names (#10825 ) cmd/k8s-operator: fix base truncating for extra long Service names StatefulSet names for ingress/egress proxies are calculated using Kubernetes name generator and the parent resource name as a base. The name generator also cuts the base, but has a higher max cap. This commit fixes a bug where, if we get a shortened base back from the generator, we cut off too little as the base that we have cut will be passed into the generator again, which will then itself cut less because the base is shorter- so we end up with a too long name again.

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.
