pkg/service: There were a couple of references here just as a reminder to change the behavior of findPort. As of v1beta3, TargetPort was always defaulted, so we could remove findDefaultPort and related tests. pkg/apiserver: The tests were using versioned API codecs for some of their encoding tests. Necessary API types had to be written and registered with the fake versioned codecs. pkg/kubectl: Some tests were converted to current versions where it made sense.
Heapster
Heapster enables monitoring of Kubernetes Clusters using cAdvisor. The kubelet will communicate with an instance of cAdvisor running on localhost and proxy container stats to Heapster. Kubelet will attempt to connect to cAdvisor on port 4194 by default but this port can be configured with kubelet's -cadvisor_port run flag. Detailed information about heapster can be found here.
