选择第二个版本的镜像,因为这个是 Jenkins 官网里面推荐的 Docker 镜像,同时第一个也提示已经废弃了。
docker pull jenkins/jenkins
该命令直接拉取的最新版本(latest)的镜像,我们还可以选择下面几个推荐的版本:
更多 TAG 版本的 Jenkins 可以查看 Docker Hub 官网:https://registry.hub.docker.com/r/jenkins/jenkins/tags
docker inspect jenkins/jenkins
mkdir -p /data/jenkins_home
chmod 777 /data/jenkins_home
注意: 创建挂载目录的同时要给该目录配置权限 777,如果权限不足的话,到时进行目录挂载的时候会失败导致无法启动 Jenkins 容器。
docker run -d \
-p 8888:8080 \
-p 50000:50000 \
-v /data/jenkins_home:/var/jenkins_home \
-v /etc/localtime:/etc/localtime \
--restart=always \
--name=jenkins \
jenkins/jenkins
-d
:后台运行容器;-p 8888:8080
:将容器的 8080 端口映射到服务器的 8888 端口;-p 50000:50000
:将容器的 50000 端口映射到服务器的 50000 端口;-v /data/jenkins_home:/var/jenkins_home
:将容器中 Jenkins 的工作目录挂载到服务器的/data/jenkins_home;-v /etc/localtime:/etc/localtime
:让容器使用和服务器同样的时间设置;--restart=always
:设置容器的重启策略为 Docker 重启时自动重启;--name=jenkins
:给容器起别名;查看是否在运行:
[root@localhost ~]# docker ps -a

查看启动日志:
[root@localhost ~]# docker logs jenkins

如果没有启动成功的话,可以排查一下挂载的目录是否正确,比如是否配了目录权限等。
在访问 Jenkins 页面前,我们需要对 Jenkins 的插件配置内容修改成内容的镜像加速地址
因为目录进行了挂载,可以直接在宿主机进行修改配置
cd /data/jenkins_home/updates
sed -i 's#https://updates.jenkins.io/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
修改配置后重启jenkins
docker restart jenkins
配置好后,访问 Jenkins 页面,地址为:IP + 容器的8080端口所映射到服务器上的端口
宿主机或者容器根据提示查看密码
宿主机路径
:/data/jenkins_home/secrets/initialAdminPassword容器路径
:/var/jenkins_home/secrets/initialAdminPassword[root@localhost ~]# cat /data/jenkins_home/secrets/initialAdminPassword

选择安装推荐的插件即可,下面是推荐的插件安装页面:
安装完成后,会进入管理员创建页面,可以选择使用admin账户继续,也可以创建一个新的管理员用户
