Kubeadm: Kubeadm 配置文档/示例？

@Lokicity据我了解，您无法在控制计划运行时动态更改其配置。 您将不得不重新启动该组件。

至于token问题，如果你不传入任何token，它会为你生成一个。

是的。 但是 kubeadm init 有一个 --config 允许用户传入他们的默认数据。 我可以为 api 服务器传递我想要的某些数据吗？ 例如，我想将我自己的 --tls-private-key-file 用于 api 服务器，而不是 kubeadm 生成的默认文件。
我希望能够在 kubeadm 初始化时做到这一点

此处的文档中添加了一个配置示例：

https://kubernetes.io/docs/admin/kubeadm/#config -file

@jistr跟随你的上层链接，我使用了下面的 yaml 文件

apiVersion: kubeadm.k8s.io/v1alpha1
kind: MasterConfiguration
etcd:
  endpoints:
  - http://127.0.0.1:2379

作为配置文件，但它不反映 etcd 端点（仍然为零）。

kubeadm.MasterConfiguration{TypeMeta:v1.TypeMeta{Kind:"", APIVersion:""}, API:kubeadm.API{AdvertiseAddress:"192.168.180.53", BindPort:6443}, Etcd:kubeadm.Etcd{Endpoints:[]string(nil), CAFil
e:"", CertFile:"", KeyFile:""}, Networking:kubeadm.Networking{ServiceSubnet:"10.96.0.0/12", PodSubnet:"", DNSDomain:"cluster.local"}, KubernetesVersion:"v1.6.0", CloudProvider:"", AuthorizationM
ode:"RBAC", Token:"8f6cc5.9fdf609145758fbd", TokenTTL:0, SelfHosted:false, APIServerExtraArgs:map[string]string(nil), ControllerManagerExtraArgs:map[string]string(nil), SchedulerExtraArgs:map[st
ring]string(nil), APIServerCertSANs:[]string(nil), CertificatesDir:"/etc/kubernetes/pki"}

我想知道我可能在哪里犯了错误还是代码错误？

你好，

我们遇到与@WIZARD-CXY 相同的问题。
对此有任何更新吗？

谢谢！

抄送@jamiehannaford
也许您可以看一下 etcd 切片是否未正确解析？

@WIZARD-CXY @akarasik你使用的是什么版本的kubeadm和etcd ？ 我刚刚尝试了以下方法，它对我有用：

root<strong i="9">@c1</strong>: kubeadm version
kubeadm version: version.Info{Major:"1", Minor:"6", GitVersion:"v1.6.3", GitCommit:"0480917b552be33e2dba47386e51decb1a211df6", GitTreeState:"clean", BuildDate:"2017-05-10T15:38:08Z", GoVersion:"go1.7.5", Compiler:"gc", Platform:"linux/amd64"}

root<strong i="10">@c1</strong>: curl 127.0.0.1:2379/version
{"etcdserver":"3.1.7","etcdcluster":"3.1.0"}

root<strong i="11">@c1</strong>: cat config.yaml
apiVersion: kubeadm.k8s.io/v1alpha1
kind: MasterConfiguration
etcd:
  endpoints:
  - http://127.0.0.1:2379

root<strong i="12">@c1</strong>: kubectl get pods --all-namespaces
NAMESPACE     NAME                         READY     STATUS    RESTARTS   AGE
kube-system   kube-controller-manager-c1   1/1       Running   0          49s
kube-system   kube-dns-3913472980-vxldm    0/3       Pending   0          45s
kube-system   kube-proxy-2d3q4             1/1       Running   0          45s
kube-system   kube-scheduler-c1            1/1       Running   0          56s

另外，您在哪里访问了kubeadm.MasterConfiguration结构？ 它是自动转储出来的，还是您将调试逻辑添加到文件中？

@jamiehannaford kubeadm 1.6.1 etcd 3.0.17
通过一个简单的调试打印，我得到了 kubeadm.MasterConfiguration 结构。 也许我会升级 kubeadm 今天再试一次，我会在这里更新结果。 谢谢你的帮助

@jamiehannaford kubeadm 1.6.3 就像一个魅力。

@Lokicity您还在遇到新版本的 kubeadm 的问题吗？
