docker安装jenkins
#使用docker安装jenkins
一 、拉取jenkins镜像
镜像地址
docker镜像配置文档
#拉取镜像
docker pull jenkins/jenkins
二 、运行容器
2.1 docker安装
docker run -d
-p 18081:8080 -p 50000:50000
#数据文件挂载
-v /usr/local/use_data/jenkins/data:/var/jenkins_home
#时间同步
-v /etc/localtime:/etc/localtime --name jenkins_01
jenkins/jenkins:latest
注意事项：可能会出现的错误
-
WARNING: IPv4 forwarding is disabled. Networking will not work.
解决方法：
vim /etc/sysctl.conf #配置转发 net.ipv4.ip_forward=1 #重启服务，让配置生效 systemctl restart network #查看是否成功,如果返回为“net.ipv4.ip_forward = 1”则表示成功 sysctl net.ipv4.ip_forward -
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?解决方法：
需要修改下目录权限, 因为当映射本地数据卷时，/usr/local/use_data/jenkins目录的拥有者为root用户，而容器中jenkins user的uid为1000
执行如下命令即可：chown -R 1000:1000 /usr/local/use_data/jenkins
建议：在运行容器前先配合好
2.2 window安装
-
Jenkins下载
-
使用管理员权限运行cmd，然后执行.msi安装包
-
安装完成后自动加到服务自动运行
-
修改端口号
到安装目录下，找到jenkins.xml
-
重启服务
三 、登录界面
-
关闭防火墙
# CentOS7环境 # 临时关闭 systemctl stop firewalld # 禁止开机启动 systemctl disable firewalld -
访问路径：http://192.168.xxx.xxx:18081
-
获取登录密码
#进入jenkins容器 docker exec -it 容器id /bin/bash #查看密匙 cat /var/jenkins_home/secrets/initialAdminPassword -
登录界面
-
选择安装推荐插件
-
新建一个管理员账户
四、配置插件
4.1 安装插件
-
安装maven插件
-
安装git插件
4.2 全局工具配置
- 安装jdk、git、maven
如果在安装的时候有些组件安装失败，可以后续根据页面上提示的插件，重新安装
**Manage Jenkins（**系统管理） -> Manage Plugins（插件管理） -> available（可选插件）
搜索插件然后安装，最后重启jenkins
-
maven的settings.xml配置信息
使用docker cp放进容器中
#从主机复制到容器 sudo docker cp settings.xml containerID:container_path
五、构建maven项目
5.1 新建任务
5.2 JDK安装失败处理
因为JDK是自动安装的，而Oracle的JDK需要登录才能下载，所以会出现以下错误
点击Your Oracle account doesn't appear valid. Please specify a valid username/password这个链接
5.3 有可能会出现的nexus或者maven的jar包问题，docker host需要本机安装等等
这里给出pom.xml文件

本地Maven仓库文件夹没有权限提示错误
#进入docker 容器
docker exec -it -u root ${containId} /bin/bash
#赋予权限
chmod +rw ./repository
5.4 查看打包结果
六 、推荐安装方式
推荐直接安装在centos系统中，原因：
- maven、git插件可以复用
- maven本地仓库方便复制
