安装必要工具

本次实验你将会安装一些实用的命令行工具, 用来完成这份指南,这包括 cfsslcfssljson 以及 kubectl

安装 CFSSL

cfssl 网站 下载 cfsslcfssljson 并安装:

OS X

curl -o cfssl https://storage.googleapis.com/kubernetes-the-hard-way/cfssl/1.4.1/darwin/cfssl
curl -o cfssljson https://storage.googleapis.com/kubernetes-the-hard-way/cfssl/1.4.1/darwin/cfssljson
chmod +x cfssl cfssljson
sudo mv cfssl cfssljson /usr/local/bin/

或者使用 Homebrew 来安装

brew install cfssl

Linux

wget -q --show-progress --https-only --timestamping \
https://storage.googleapis.com/kubernetes-the-hard-way/cfssl/1.4.1/linux/cfssl \
https://storage.googleapis.com/kubernetes-the-hard-way/cfssl/1.4.1/linux/cfssljson
chmod +x cfssl cfssljson
sudo mv cfssl cfssljson /usr/local/bin/

验证

验证 cfssl 的版本为 1.4.1 或是更高:

$ cfssl version
Version: 1.4.1
Runtime: go1.12.12
$ cfssljson --version
Version: 1.4.1
Runtime: go1.12.12

安装 kubectl

kubectl 命令行工具用来与 Kubernetes API Server 交互,可以在 Kubernetes 官方网站下载并安装 kubectl

OS X

curl -o kubectl https://storage.googleapis.com/kubernetes-release/release/v1.18.6/bin/darwin/amd64/kubectl
chmod +x kubectl
sudo mv kubectl /usr/local/bin/

Linux

wget https://storage.googleapis.com/kubernetes-release/release/v1.18.6/bin/linux/amd64/kubectl
chmod +x kubectl
sudo mv kubectl /usr/local/bin/

验证

验证 kubectl 的安装版本为 1.18.6 或是更高

kubectl version --client

输出为

Client Version: version.Info{Major:"1", Minor:"18", GitVersion:"v1.18.6", GitCommit:"dff82dc0de47299ab66c83c626e08b245ab19037", GitTreeState:"clean", BuildDate:"2020-07-15T16:58:53Z", GoVersion:"go1.13.9", Compiler:"gc", Platform:"linux/amd64"}
