1.安装好jenkins后，输完页面密码，这时候jenkins需要的文件目录已经生成完毕了, 切换到updates目录

docker exec -it b13e815bf589 /bin/bash



cd /var/jenkins_home/updates

2.使用sed命令替换为国内地址

sed -i 's/http:\/\/updates.jenkins-ci.org\/download/https:\/\/mirrors.tuna.tsinghua.edu.cn\/jenkins/g' default.json && sed -i 's/http:\/\/www.google.com/https:\/\/www.baidu.com/g' default.json

3.重启jenkins
systemctl restart jenkins
//docker 安装：
docker restart jenkins

docker restart b13e815bf589
