This follows the pattern `kubectl` uses for logging. There are two remaining glog.Infof call that cannot be removed easily. One glog call comes from kubelet validation which calls features.SetFromMap. The other comes from test/e2e during kernel validation. Mostly fixes kubernetes/kubeadm#852 Signed-off-by: Chuck Ha <ha.chuck@gmail.com>

│ KUBEADM IS CURRENTLY IN BETA │
|
|
│ │
|
|
│ But please, try it out and give us feedback at: │
|
|
│ https://github.com/kubernetes/kubeadm/issues │
|
|
│ and at-mention @kubernetes/sig-cluster-lifecycle-bugs │
|
|
│ or @kubernetes/sig-cluster-lifecycle-feature-requests │

└──────────────────────────────────────────────────────────┘

|
|
Example usage:
|
|
|
|
Create a two-machine cluster with one master (which controls the cluster),
|
|
and one node (where your workloads, like Pods and Deployments run).
|
|
|
|
┌──────────────────────────────────────────────────────────┐
|
|
│ On the first machine: │
|
|
├──────────────────────────────────────────────────────────┤
|
|
│ master# kubeadm init │
|
|
└──────────────────────────────────────────────────────────┘
|
|
|
|
┌──────────────────────────────────────────────────────────┐
|
|
│ On the second machine: │
|
|
├──────────────────────────────────────────────────────────┤
|
|
│ node# kubeadm join <arguments-returned-from-init> │
|
|
└──────────────────────────────────────────────────────────┘
|
|
|
|
You can then repeat the second step on as many other machines as you like.
