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
