ProblemAPI is going to address this kind of problems in the future, but we need a fix for the 1.3.\r\n\r\nEither Kubelet or KubeProxy needs to update a NodeStatus with the information that Node networking is down. I suggests that we reuse NodeReady Condition for this, as this would make the rest of ControlPlane work out of the box. We will replace this fix with the ProblemAPI use in the future. @thockin @dchen1107 \r\n\r\nAnother option, which requires more work, is creating a completely new NodeCondition type to handle this case. This would require making Scheduler aware of this new Condition. @davidopp @bgrant0607 \r\n\r\n@alex-mohr @wojtek-t @fgrzadkowski @zmerlynn "},"comment":{"url":"https://api.github.com/repos/kubernetes/kubernetes/issues/comments/223686584","html_url":"https://github.com/kubernetes/kubernetes/issues/25543#issuecomment-223686584","issue_url":"https://api.github.com/repos/kubernetes/kubernetes/issues/25543","id":223686584,"user":{"login":"wojtek-t","id":10743879,"avatar_url":"https://avatars.githubusercontent.com/u/10743879?v=3","gravatar_id":"","url":"https://api.github.com/users/wojtek-t","html_url":"https://github.com/wojtek-t","followers_url":"https://api.github.com/users/wojtek-t/followers","following_url":"https://api.github.com/users/wojtek-t/following{/other_user}","gists_url":"https://api.github.com/users/wojtek-t/gists{/gist_id}","starred_url":"https://api.github.com/users/wojtek-t/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/wojtek-t/subscriptions","organizations_url":"https://api.github.com/users/wojtek-t/orgs","repos_url":"https://api.github.com/users/wojtek-t/repos","events_url":"https://api.github.com/users/wojtek-t/events{/privacy}","received_events_url":"https://api.github.com/users/wojtek-t/received_events","type":"User","site_admin":false},"created_at":"2016-06-03T20:29:50Z","updated_at":"2016-06-03T20:29:50Z","body":"I think we've seen it the day before yesterday during our tests - @gmarek can you please confirm?"}}
