docker安装jenkins
https://blog.csdn.net/mmd0308/article/details/77206563?locationNum=6&fps=1
查看docker的某个容器的日志
docker logs [容器名称]
jenkins启动命令
sudo docker run -d --name enkins -p 8081:8080 -p 50000:50000 --volume $PWD/jenkins:/var/jenkins_home jenkins
本地端口映射成8081
[ludvikwoo ~/SoftwareData]$docker logs myjenkins
touch: cannot touch '/var/jenkins_home/copy_reference_file.log': Permission denied
Can not write to /var/jenkins_home/copy_reference_file.log. Wrong volume permissions?
sudo chown -R 1000 jenkins
然后重启
docker start myjenkins
http://127.0.0.1:8081/jenkins
打开 ip地址:8080 网页，按照提示
/var/jenkins_home/secrets/initialAdminPassword
在里面找到初始密码 要把/var/jenkins_home 换成 /home/jenkins_home
cat /home/jenkins_home/secrets/initialAdminPassword
按照对应的密码初始化，开始Jenkins的使用吧
