docker-compose安装JenKins
一、Jenkins
Jenkins是一个开源软件项目,是基于Java开发的一种持续集成工具,用于监控持续重复的工作,旨在提供一个开放易用的软件平台,使软件的持续集成变成可能。
二、安装JenKins的前提条件
硬件 | 最低要求 | 推荐 |
---|---|---|
内存 | 256M | 1GB或更高 |
硬盘 | 1GB(作为一个Docker容器运行jenkins的话推荐10GB) | 50GB或更高 |
三、部署规划
服务器IP | 192.168.113.48 |
---|---|
端口 | 8928 |
安装目录 | /home/work/docker-jenkins |
数据卷映射目录 | /home/work/docker-jenkins/data |
四、安装JenKins
-
在安装目录下创建docker-jenkins目录,创建成功后进入该目录
mkdir docker-jenkins cd docker-jenkins
-
新建并按照规划编辑docker-compose.yml文件,编辑完后保存退出
vim docker-compose.yml
version: '3' services: jenkins: image: 'jenkins/jenkins:lts' container_name: jenkins restart: always environment: - TZ=Asia/Shanghai ports: - '8928:8080' - '50000:50000' volumes: - '/etc/localtime:/etc/localtime' - './data:/var/jenkins_home' - '/var/run/docker.sock:/var/run/docker.sock' - '/usr/bin/docker:/usr/bin/docker'
-
在安装目录下执行相关命令,启动容器
docker-compose up -d
执行命令后发现服务并没有运行,查看日志:

通过日志发现,是由于权限不足导致服务没有正常运行, 因为当映射本地数据卷时,/home/work/docker-jenkins目录的拥有者为root用户,而容器中jenkins user的uid为1000;执行以下命令即可。
chown -R 1000:1000 /home/work/docker-jenkins
执行命令后会发现服务已正常启动:
[root@node03 docker-jenkins]# chown -R 1000:1000 /home/work/docker-jenkins You have new mail in /var/spool/mail/root [root@node03 docker-jenkins]# docker-compose ps Name Command State Ports --------------------------------------------------------------------------------------------------- jenkins /sbin/tini -- /usr/local/b ... Up 0.0.0.0:50000->50000/tcp, 0.0.0.0:8928->8080/tcp
五、验证Jenkins
-
在浏览器输入ip:端口,页面提示解锁Jenkins
根据页面提示信息,密码路径(路径为容器中路径)如上图所示,在此之前已经做了数据映射,不用登录容器,直接在宿主机查看即可:
[root@node03 docker-jenkins]# cat /home/work/docker-jenkins/data/secrets/initialAdminPassword d1d17726052b4716acd6315a276fd0fb
将查出来的密码复制到浏览器中即可。点击"继续"就会出现以下界面:
根据自己所需进行选择即可。(建议选择“安装推荐的插件”,若插件安装失败,多试几次即可)
插件下载较慢是由于服务器在国外,所以下载缓慢,可以更换为国内插件源:
