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>. kubeadm: add configuration option to not taint master **What this PR does / why we need it**: Although tainting the master is normally a good and proper thing to do in some situations (docker for mac in our case, but I suppose minikube and such as well) having a single host configuration is desirable. In linuxkit we have a [workaround](443e47c408/projects/kubernetes/kubernetes/kubeadm-init.sh (L19...L22)) to remove the taint after initialisation. With the change here we could simply populate `/etc/kubeadm/kubeadm.yaml` with `noTaintMaster: true` instead and have it never be tainted in the first place. I have only added this to the config file and not to the CLI since AIUI the latter is somewhat deprecated. The code also arranges to _remove_ an existing taint if it is unwanted. I'm unsure if this behaviour is correct or desirable, I think a reasonable argument could be made for leaving an existing taint in place too. Signed-off-by: Ian Campbell <ijc@docker.com> **Release note**: Since the requirement for this option is rather niche and not best practice in the majority of cases I'm not sure if it warrants mentioning in the release notes? If it were then perhaps ```release-note `kubeadm init` can now omit the tainting of the master node if configured to do so in `kubeadm.yaml`. ```		2018-02-12 15:44:41 -08:00
