打造超级富容器开发环境（八）：下载和编译其它软件

概述

很多开源软件并不支持通过包管理器安装，或者包管理器中的版本比较滞后，希望安装的是最新版本，这时候我们就需要自己下载最新二进制，或者自己编译二进制进行安装。

本文介绍日常开发中常用的工具安装方法。

安装 kubectl 及其插件

kubectl 是云原生玩家最常用的工具，除了 kubectl 本身之外，还有 kubectl 的一些列常用插件，我们可以单独用个脚本文件来安装 kubectl 及其插件：

代码语言：bash复制

#!/bin/bash

set -ex

# kubectl
wget -O /usr/local/bin/kubectl "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/$(dpkg --print-architecture)/kubectl"
chmod  x /usr/local/bin/kubectl

# krew
(
	set -x
	cd "$(mktemp -d)" &&
		KREW="krew-linux_$(dpkg --print-architecture)" &&
		curl -fsSLO "https://github.com/kubernetes-sigs/krew/releases/latest/download/${KREW}.tar.gz" &&
		tar zxvf "${KREW}.tar.gz" &&
		./"${KREW}" install krew
)
export PATH="${KREW_ROOT:-$HOME/.krew}/bin:$PATH"
kubectl krew index add kvaps https://github.com/kvaps/krew-index
kubectl krew update
kubectl krew install kvaps/node-shell
kubectl krew install ctx
kubectl krew install explore
kubectl krew install fuzzy
kubectl krew install get-all
kubectl krew install kc
kubectl krew install konfig
kubectl krew install neat
kubectl krew install ns
kubectl krew install status
kubectl krew install view-cert
kubectl krew install whoami

安装其它工具

其它很多软件可能很多需要从 GitHub 获取最新 release 版本号、下载和编译等复杂操作，我们可以抽取一些公共函数和变量，单独放到一个脚本里执行：

代码语言：bash复制

#!/bin/bash

set -ex

export GITHUB_TOKEN="****************************************"
export DEBIAN_FRONTEND=noninteractive
export PATH="$PATH:/opt/go/bin:/root/go/bin"
export PATH="$PATH:/root/.cargo/bin"
export ARCH=$(dpkg --print-architecture)
export ARCH2=$(arch)
export OS=$(uname | tr '[:upper:]' '[:lower:]')
export OS_UPPER=$(uname)

clean_tmp() {
	cd /tmp
	rm -rf /tmp/tmp
}

gotmp() {
	mkdir -p /tmp/tmp
	cd /tmp/tmp
}

getLatestRelease() {
	repo="$1"
	release=$(curl -s --header "Authorization: Bearer ${GITHUB_TOKEN}" "https://api.github.com/repos/${repo}/releases/latest" | grep -Po '"tag_name": "vK[^"]*')
	echo "${release}"
}
