替换国内源

cd /root/jenkins/data/updates
sed -i 's/https:\/\/updates.jenkins.io\/download/https:\/\/mirrors.tuna.tsinghua.edu.cn\/jenkins/g' default.json && sed -i 's/https:\/\/www.google.com/https:\/\/www.baidu.com/g' default.json

# 重启使配置生效
docker restart jenkins

安装查看密码

cat /root/jenkins/data/secrets/initialAdminPassword
