kube-generate-all: kube-generate-deepcopy ## Refresh generated files for Tailscale Kubernetes Operator
	./tool/go generate ./cmd/k8s-operator

# Tailscale operator watches Connector custom resources in a Kubernetes cluster
# and caches them locally. Caching is done implicitly by controller-runtime
# library (the middleware used by Tailscale operator to create kube control
# loops). When a Connector resource is GET/LIST-ed from within our control loop,
# the request goes through the cache. To ensure that cache contents don't get
# modified by control loops, controller-runtime deep copies the requested
# object. In order for this to work, Connector must implement deep copy
# functionality so we autogenerate it here.
