1. 安裝kubectl
curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl && chmod +x kubectl && sudo mv kubectl /usr/local/bin/
下載指定版本，例如下載v1.9.0版本
curl -LO https://storage.googleapis.com/kubernetes-release/release/v1.9.0/bin/linux/amd64/kubectl && chmod +x kubectl && sudo mv kubectl /usr/local/bin/
2. 安裝minikube
minikube的源碼地址：https://github.com/kubernetes/minikube
2.1 安裝minikube
以下命令為安裝latest版本的minikube。
curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/
安裝指定版本可到https://github.com/kubernetes/minikube/releases下載對應版本。
例如：以下為安裝v0.28.2版本
curl -Lo minikube https://storage.googleapis.com/minikube/releases/v0.28.2/minikube-linux-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/
2.2 minikube命令幫助
Minikube is a CLI tool that provisions and manages single-node Kubernetes clusters optimized for development workflows.
Usage:
minikube [command]
Available Commands:
addons Modify minikube's kubernetes addons
cache Add or delete an image from the local cache.
completion Outputs minikube shell completion for the given shell (bash or zsh)
config Modify minikube config
dashboard Opens/displays the kubernetes dashboard URL for your local cluster
delete Deletes a local kubernetes cluster
docker-env Sets up docker env variables; similar to '$(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安裝k8s集群
3.1. minikube start
可以以Docker的方式運行k8s的組件，但需要先安裝Docker(可參考Docker安裝)，啟動參數使用--vm-driver=none。
minikube start --vm-driver=none
安裝指定版本的kubernetes集群
# 查閱版本 minikube get-k8s-versions # 選擇版本啟動 minikube start --kubernetes-version v1.7.3 --vm-driver=none
3.2. minikube status
$ minikube status minikube: Running cluster: Running kubectl: Correctly Configured: pointing to minikube-vm at 172.16.94.139
3.3. minikube stop
minikube stop 命令可以用來停止集群。 該命令會關閉 minikube 虛擬機，但將保留所有集群狀態和數據。 再次啟動集群將恢復到之前的狀態。
3.4. minikube delete
minikube delete 命令可以用來刪除集群。 該命令將關閉並刪除 minikube 虛擬機。沒有數據或狀態會被保存下來。

4.2. dashboard
通過訪問ip:port，例如：http://172.16.94.139:30000/，可以訪問k8s的dashboard控制台。
