一个Kubernetes集群由分布式存储etcd、控制节点controller以及服务节点Node组成。
|
|
|
|
|
|
|
|
|
|
|
|
- 控制节点主要负责整个集群的管理，比如容器的调度、维护资源的状态、自动扩展以及滚动更新等
|
|
|
|
|
|
- 服务节点是真正运行容器的主机，负责管理镜像和容器以及cluster内的服务发现和负载均衡
|
|
|
|
|
|
- etcd集群保存了整个集群的状态

## Kubernetes单机版

创建Kubernetes cluster（单机版）最简单的方法是[minikube](https://github.com/kubernetes/minikube):
|
|
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
|
$ minikube start
|
|
|
|
|
|
Starting local Kubernetes cluster...
|
|
|
|
|
|
Kubectl is now configured to use the cluster.
|
|
|
|
|
|
$ kubectl cluster-info
|
|
|
|
|
|
Kubernetes master is running at https://192.168.64.12:8443
|
|
|
|
|
|
kubernetes-dashboard is running at https://192.168.64.12:8443/api/v1/proxy/namespaces/kube-system/services/kubernetes-dashboard
|
|
|
|
|
|
|
|
|
|
|
|
To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
|
|
|
|
|
|
```
|
|
|
|
|
