安装Client 工具

本次实验你将会安装一些实用的指令工具, 用来完成这整份教学 : cfssl, cfssljson, and kubectl

从cfssl repository下载cfssl and cfssljson 并安装

OS X

curl -o cfssl https://pkg.cfssl.org/R1.2/cfssl_darwin-amd64
curl -o cfssljson https://pkg.cfssl.org/R1.2/cfssljson_darwin-amd64

chmod +x cfssl cfssljson

sudo mv cfssl cfssljson /usr/local/bin/

Linux

wget -q --show-progress --https-only --timestamping \
  https://pkg.cfssl.org/R1.2/cfssl_linux-amd64 \
  https://pkg.cfssl.org/R1.2/cfssljson_linux-amd64

chmod +x cfssl_linux-amd64 cfssljson_linux-amd64

sudo mv cfssl_linux-amd64 /usr/local/bin/cfssl

sudo mv cfssljson_linux-amd64 /usr/local/bin/cfssljson

验证

验证cfssl的版本为1.2.0或是更高

cfssl version

输出为

Version: 1.2.0
Revision: dev
Runtime: go1.6

cfssljson的指令工具没有提供方法来列出版本

安装kubectl

kubectk指令工具是用来与 Kubernetes API Server沟通的, 下载并安装kubectl ,可在官方取得

OS X

curl -o kubectl https://storage.googleapis.com/kubernetes-release/release/v1.8.0/bin/darwin/amd64/kubectl

chmod +x kubectl

sudo mv kubectl /usr/local/bin/

Linux

wget https://storage.googleapis.com/kubernetes-release/release/v1.8.0/bin/linux/amd64/kubectl

chmod +x kubectl

sudo mv kubectl /usr/local/bin/

验证

验证kubectl的安装版本为 1.8.0 或是更高

kubectl version --client

输出为

Client Version: version.Info{Major:"1", Minor:"8", GitVersion:"v1.8.0", GitCommit:"6e937839ac04a38cac63e6a7a306c5d035fe7b0a", GitTreeState:"clean", BuildDate:"2017-09-28T22:57:57Z", GoVersion:"go1.8.3", Compiler:"gc", Platform:"darwin/amd64"}
