Deploy kubelet and kube-apiserver as containers kubelet via docker kube-apiserver as a static pod Fixed etcd service start to be more tolerant of slow start. Workaround for kube_version to stay in download role, but not download an files by creating a new "nothing" download entry. 2016-07-08 09:59:21 +00:00			`---`
Purge legacy cleanup tasks from older than 1 year (#4450) We don't need to support upgrades from 2 year old installs, just from the last major version.

Master component and kubelet container upgrade fixes * Fixes an issue where apiserver and friends (controller manager, scheduler) were prevented from restarting after manifests/secrets are changed. This occurred when a replaced kubelet doesn't reconcile new master manifests, which caused old master component versions to linger during deployment. In my case this was causing upgrades from k8s 1.6/1.7 -> k8s 1.8 to fail * Improves transitions from kubelet container to host kubelet by preventing issues where kubelet container reappeared during the deployment 2017-11-08 07:40:33 +00:00			`shell: "docker ps -af name=k8s_{{item}}* -q \| xargs --no-run-if-empty docker rm -f"`
