rancher pod 上搭建压测环境

by 夏泽民 May 16, 2021

docker 一般用的都是apline镜像，不支持yum等工具，但是支持apk，用apk安装git 和ssh ，然后就可以开始拉代码做压测环境了

apk add git
apk update
apk list |grep golang
wget https://dl.google.com/go/go1.10.3.linux-amd64.tar.gz
tar -C /usr/local -xzf go1.10.3.linux-amd64.tar.gz
export PATH=$PATH:/usr/local/go/bin
go version
git version
