kubectl的插件安装工具krew

最近得知一个kubectl插件安装工具，叫做krew。

官网地址是：Krew – kubectl plugin manager

安装krew

按照官网的做法，一直安装失败，于是拆解步骤，一步一步下载离线安装。

1、下载krew.yaml

地址：https://github.com/kubernetes-sigs/krew-index/blob/master/plugins/krew.yaml

这里我把原文贴出来，大家可以直接copy使用

2、下载安装包

根据官网给的命令中的这一部分，大家执行的时候，可能会出错，但是至少可以看到一个url地址

set -x; cd "$(mktemp -d)" &&OS="$(uname | tr '[:upper:]' '[:lower:]')" &&ARCH="$(uname -m | sed -e 's/x86_64/amd64/' -e 's/\(arm\)\(64\)\?.*/\1\2/' -e 's/aarch64$/arm64/')" &&KREW="krew-${OS}_${ARCH}" &&curl -fsSLO "https://github.com/kubernetes-sigs/krew/releases/latest/download/${KREW}.tar.gz"
