使用minikube安装kubernetes

以下内容基于Linux系统，特别为Ubuntu系统

hashtag
1. 安装kubectl

curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl && chmod +x kubectl && sudo mv kubectl /usr/local/bin/

下载指定版本，例如下载v1.9.0版本

curl -LO https://storage.googleapis.com/kubernetes-release/release/v1.9.0/bin/linux/amd64/kubectl && chmod +x kubectl && sudo mv kubectl /usr/local/bin/

2.1 安装minikube

以下命令为安装latest版本的minikube。

curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/

安装指定版本可到https://github.com/kubernetes/minikube/releases下载对应版本。

例如：以下为安装v0.28.2版本

2.2 minikube命令帮助

Minikube is a CLI tool that provisions and manages single-node Kubernetes clusters optimized for development workflows.

Usage:
  minikube [command]

Available Commands:
  addons           Modify minikube's kubernetes addons
  cache            Add or delete an image from the local cache.
  completion       Outputs minikube shell completion for the given shell (bash or zsh)
  config           Modify minikube config
  dashboard        Opens/displays the kubernetes dashboard URL for your local cluster
  delete           Deletes a local kubernetes cluster
  docker-env       Sets up docker env variables; similar to '$(docker-machine env)'
  get-k8s-versions Gets the list of Kubernetes versions available for minikube when using the localkube bootstrapper
  ip               Retrieves the IP address of the running cluster
  logs             Gets the logs of the running localkube instance, used for debugging minikube, not user code
  mount            Mounts the specified directory into minikube
  profile          Profile sets the current minikube profile
  service          Gets the kubernetes URL(s) for the specified service in your local cluster
  ssh              Log into or run a command on a machine with SSH; similar to 'docker-machine ssh'
  ssh-key          Retrieve the ssh identity key path of the specified cluster
  start            Starts a local kubernetes cluster
  status           Gets the status of a local kubernetes cluster
  stop             Stops a running local kubernetes cluster
  update-check     Print current and latest version number
  update-context   Verify the IP address of the running cluster in kubeconfig.
  version          Print the version of minikube

Flags:
      --alsologtostderr                  log to standard error as well as files
  -b, --bootstrapper string              The name of the cluster bootstrapper that will set up the kubernetes cluster. (default "localkube")
      --log_backtrace_at traceLocation   when logging hits line file:N, emit a stack trace (default :0)
      --log_dir string                   If non-empty, write log files in this directory
      --loglevel int                     Log level (0 = DEBUG, 5 = FATAL) (default 1)
      --logtostderr                      log to standard error instead of files
  -p, --profile string                   The name of the minikube VM being used.
	This can be modified to allow for multiple minikube instances to be run independently (default "minikube")
      --stderrthreshold severity         logs at or above this threshold go to stderr (default 2)
  -v, --v Level                          log level for V logs
      --vmodule moduleSpec               comma-separated list of pattern=N settings for file-filtered logging

Use "minikube [command] --help" for more information about a command.

3. 使用minikube安装k8s集群

hashtag
3.1. minikube start

可以以Docker的方式运行k8s的组件，但需要先安装Docker(可参考Docker安装)，启动参数使用--vm-driver=none。

例如：

安装指定版本的kubernetes集群

hashtag
3.2. minikube status

hashtag
3.3. minikube stop

minikube stop 命令可以用来停止集群。 该命令会关闭 minikube 虚拟机，但将保留所有集群状态和数据。 再次启动集群将恢复到之前的状态。

hashtag
3.4. minikube delete

minikube delete 命令可以用来删除集群。 该命令将关闭并删除 minikube 虚拟机。没有数据或状态会被保存下来。

4. 查看部署结果

hashtag
4.1. 部署组件

hashtag
4.2. dashboard

通过访问ip:port，例如：http://172.16.94.139:30000/，可以访问k8s的dashboard控制台。
