For kubeadm I can do something like this to enable the deprecated APIs in k8s 1.16:

apiVersion: kubeadm.k8s.io/v1beta1
kind: ClusterConfiguration
apiServer:
  extraArgs:
    runtime-config: "apps/v1beta1=true,apps/v1beta2=true,extensions/v1beta1/daemonsets=true,extensions/v1beta1/deployments=true,extensions/v1beta1/replicasets=true,extensions/v1beta1/networkpolicies=true,extensions/v1b

我刚看了一下其他人都好像有这个问题，不过还是看见有人数可以用renew的办法，我也尝试了一下
kubeadm alpha phase all
初步看好像是续期了一年的样子，但由于我是vmware的1master 3node的。。没有环境测试高可用情况下这样renew证书的话，其他master要怎么操作。

另外贴一下下面的help信息
[root@t0 etcd]# kubeadm alpha phase --help
This command is not meant to be run on its own. See list of available subcommands.

[root@t0 etcd]# kubeadm alpha certs renew --help

Current guide does not result in working cluster.

Dashboard install instructions not current (can fix by using "offical" arm installation of kubernetes-dashboard-arm).
No "heapster.yaml" in demos folder. Seems to be deprecated in current repo, but instructions still reference.

The current video shows an error about resizing image and does not show the new subcommands create, start, list... It should be updated to match the last version of kube-spawn.

Some files , it is observed that "Copyright 2017 The Kubernetes Authors." , should it be The CNI-Genie Authors ?
Example:
CNI-Genie/controllers/network-admission-controller/gencerts.sh
CNI-Genie/controllers/network-policy-controller/signals/signal_posix.go

A task I've found error-prone and also poorly documented is decommissioning worker/master nodes in a cluster. It'd be really helpful to have some kurl-specific docs on https://kurl.sh/docs.

Also rebooting worker/master nodes.

As per our discussion, after having curled the latest version of kn and run kn apply in an already existing working directory (hence previously initialized with an older version of kn), I am getting this error:

/opt/KubeNow/bin/ssh-agent-wrapper: line 7: kn-apply: command not found

By running ls bin in the working folder I noticed that the command kn-apply does not exist. This is becau

From Kubelet's startup logs via journalctl -f, when running Kubernetes 1.10+:

if someone wants to use their own repos instead of relying on the repos listed in our ansible playbooks, we need to have documentation for this.
It will good for our team as well, so that we can avoid running into ovs related issues hence onwards.

We should be able to detect if certificates have expired and then use kubeadm for rotating them.

We should investigate if we can do that as nodes are not accesible once they have been provisioned. Maybe we will need some triggers block in a null_resource, like this:

resource "null_resource" "renew_certs" {
 

many people would like to see this feature added, especially when we're talking for projects like openstack-helm and kolla-kubernetes.

i'd like to see CoreOS supported for the project, and this issue is just to track this and let the community know that this is the project's intention. i know we're
