are running kubernetes 1.2.4 on GKE. We observed that when we increased load on our system by 20% our outbound connections from our pods started to fail 80% of the time. After much diagnosing we found that our cluster was running with just one `kube-dns` pod. This pod was being hammered and resulted in failures to resolve DNS requests.\r\n\r\nOur cluster started smaller (3x VM 8 core if i remember correctly) and is currently almost doubled in size/cores (10x VM 4 core).\r\n\r\nCreating a new cluster in GKE of the same size gave us three `kube-dns` pods. My expectations would be that the amound of `kube-dns` pods would scale by load (using a HPA?) or that the pods would scale by cluster size (using deamonsets?). Not that the amound of `kube-dns` pods would be based on the initial cluster size when creating it in GKE.\r\n\r\n```\r\nClient Version: version.Info{Major:\"1\", Minor:\"2\", GitVersion:\"v1.2.4\", GitCommit:\"3eed1e3be6848b877ff80a93da3785d9034d0a4f\", GitTreeState:\"clean\"}\r\nServer Version: version.Info{Major:\"1\", Minor:\"2\", GitVersion:\"v1.2.4\", GitCommit:\"3eed1e3be6848b877ff80a93da3785d9034d0a4f\", GitTreeState:\"clean\"}\r\n```\r\n\r\nNOTE: I do not know if this issue is superseded by the DNS changes discussed in #22823"},"comment":{"url":"https://api.github.com/repos/kubernetes/kubernetes/issues/comments/245466574","html_url":"https://github.com/kubernetes/kubernetes/issues/28497#issuecomment-245466574","issue_url":"https://api.github.com/repos/kubernetes/kubernetes/issues/28497","id":245466574,"user":{"login":"pwittrock","id":7882754,"avatar_url":"https://avatars.githubusercontent.com/u/7882754?v=3","gravatar_id":"","url":"https://api.github.com/users/pwittrock","html_url":"https://github.com/pwittrock","followers_url":"https://api.github.com/users/pwittrock/followers","following_url":"https://api.github.com/users/pwittrock/following{/other_user}","gists_url":"https://api.github.com/users/pwittrock/gists{/gist_id}","starred_url":"https://api.github.com/users/pwittrock/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/pwittrock/subscriptions","organizations_url":"https://api.github.com/users/pwittrock/orgs","repos_url":"https://api.github.com/users/pwittrock/repos","events_url":"https://api.github.com/users/pwittrock/events{/privacy}","received_events_url":"https://api.github.com/users/pwittrock/received_events","type":"User","site_admin":false},"created_at":"2016-09-08T01:13:33Z","updated_at":"2016-09-08T01:13:33Z","body":"@MrHohn @thockin @crunchie84 @girishkalele \r\n\r\nI am leaving this in the 1.4 release as a blocking issue.
