View summary of image vulnerabilities and recommendations →dockerscout quickview jenkins/jenkins:lts注：因为Jenkins容器里的用户是Jenkins，而主机用户不是Jenkins，就算是root也一样会报错：/var/jenkins_home/copy_reference_file.log: Permission denied，这个时候就需要在主机上面给主机地址赋予访问Jenkins容器的权限，Jenkins内部用的是uid 1000的userprivileged=true让容器具有root权限，便于进入容器p 8080:8080指定主机8080端口映射到Jenkins容器的8080端口（Jenkins的web访问端口）-v /home/jenkins:/var/jenkins_home容器/var/jenkins_home路径挂载到宿主机/home/jenkins路径2:jenkens在linux环境部署dockerrun-d--namejenkins-p8080:8080-p8888:8888-p50000:50000-v/usr/local/java/jdk1.8:/usr/local/src/jdk/jdk1.8-v/opt/apache-maven-3.8.8:/opt/apache-maven-3.8.8-v/home/jenkins:/var/jenkins_home--privileged=true jenkins/jenkins:lts指令说明-d：在后台运行容器-p 8080:8080 ：容器的端口8080到主机上的端口8080-p 50000:50000 ：公开主机上的 Docker 守护进程端口/usr/local/java/jdk1.8:/usr/local/src/jdk/jdk1.8 可以挂载本地的不同的jdk版本到Jenkins中，到时候在Dashboard→系统管理→全局工具配置里，配置JDK安装的不同版本和路径，也可以在Jenkins里安装指定的jdk版本-v /home/jenkins:/var/jenkins_home ：将容器的 /var/jenkins_home 目录映射到宿主机中的 /home/jenkins-data目录/opt/apache-maven-3.8.8:/opt/apache-maven-3.8.8 可以把本地的maven和settings.xml配置文件都挂载进去Jenkins容器中，到时候执行命令，指定使用的maven路径即可3:在浏览器中输入http:127.0.0.1:8080访问jenkins根据提示可以查找 /var/jenkins_home/secrets/initialAdminPassword 获取管理员密码当然我们还可以执行docker logs 指令查看4:等待几分钟，自动安装
