1. 安装kubectl
curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl && chmod +x kubectl && sudo mv kubectl /usr/local/bin/
下载指定版本，例如下载v1.9.0版本
curl -LO https://storage.googleapis.com/kubernetes-release/release/v1.9.0/bin/linux/amd64/kubectl && chmod +x kubectl && sudo mv kubectl /usr/local/bin/
2. 安装minikube
minikube的源码地址：https://github.com/kubernetes/minikube
2.1 安装minikube
以下命令为安装latest版本的minikube。
curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/
安装指定版本可到https://github.com/kubernetes/minikube/releases下载对应版本。
例如：以下为安装v0.28.2版本
curl -Lo minikube https://storage.googleapis.com/minikube/releases/v0.28.2/minikube-linux-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/
2.2 minikube命令帮助
Minikube is a CLI tool that provisions and manages single-node Kubernetes clusters optimized for development workflows.
Usage:
minikube [command]
Available Commands:
addons Modify minikube‘s kubernetes addons
cache Add or delete an image from the local cache.
completion Outputs minikube shell completion for the given shell (bash or zsh)
config Modify minikube config
dashboard Opens/displays the kubernetes dashboard URL for your local cluster
delete Deletes a local kubernetes cluster
docker-env Sets up docker env variables; similar to ‘$(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
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。
minikube start --vm-driver=none
安装指定版本的kubernetes集群
# 查阅版本 minikube get-k8s-versions # 选择版本启动 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。
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。

4.2. 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。
