Automatic merge from submit-queue. If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>. Disable session affinity for internal kuberntes service Under following conditions session affinity leads to a deadlock: - Self hosted controller-manager, where it talks to API servers via kubernetes service ClusterIP - default master-count reconcilier is used - --apiserver-count is set to >1 according to the help message - number of responsive APIServers goes below `apiserver-count` - all controller-managers happen to be hashed to APIServers which are down. What then happens is that controller managers never be able to contact APIServer, despite correctly working APIServer available. Less serious outages also possible for other consumers of kubernetes service, such as operators, kube-dns, flannel & calico, etc. There is always non zero chance, that given consumer is hashed to an apiserver which is down.
