Docker安装Jenkins
Jenkins 是一款由 Java 编写的开源的持续集成工具。在与 Oracle 发生争执后，项目从 Hudson 项目复刻。 Jenkins 提供了软件开发的持续集成服务。它运行在 Servlet 容器中（例如 Apache Tomcat）。它支持软件配置管理（SCM）工具（包括 AccuRev SCM、CVS、Subversion、Git、Perforce、Clearcase 和 RTC），可以执行基于 Apache Ant 和 Apache Maven 的项目，以及任意的 Shell 脚本和 Windows 批处理命令。Jenkins 的主要开发者是川口耕介。Jenkins 是在 MIT 许可证下发布的自由软件。 可以通过各种手段触发构建。例如提交给版本控制系统时被触发，也可以通过类似 Cron 的机制调度，也可以在其他的构建已经完成时，还可以通过一个特定的 URL 进行请求。 Wikipedia

创建并启动容器
创建容器
- 将容器名设置为
jenkins - 容器端口与主机端口进行同步绑定
- 主机
/var/jenkins_home与容器目录映射

cc0287527ff2d4f24b169f134334477d3就是默认的 admin 密码了
此时关闭终端 jenkins 自然会退出
启动容器
重新打开终端用 docker 启动jenkins容器
$ docker start jenkins
jenkins
确认容器是否正常运行
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
6246498b082a jenkins/jenkins:lts "/sbin/tini -- /usr/…" 14 minutes ago Up 12 minutes 0.0.0.0:8080->8080/tcp, :::8080->8080/tcp, 0.0.0.0:50000->50000/tcp, :::50000->50000/tcp jenkins
可以看到容器已经成功运行
Jenkins 初体验
启动 Jenkins
打开浏览器地址栏输入localhost:8080即可进入 jenkins
配置 Jenkins(Getting Started)
首次登陆 Jenkins 会进入默认配置向导
解锁以进行下一步配置(Unlock Jenkins)
为确保管理员登陆需要输入管理员密码(为初次构建容器输出时密码)
管理员密码也保存在容器的/var/jenkins_home/secrets/initialAdminPassword
自定义你的扩展补丁(Customize Jenkins)
有两种选项供我们选择, 由于不是特殊使用我个人选择第一项安装推荐补丁
- Install suggested plugins
- Select plugins to install
下面就是进行安装补丁过程(需要 7-8 分钟的时间)
包括一些常用的如 Git, SSH, Email Extension, Ant, Gradle 等工具
配置管理员信息(Setup of an admin user)
这里添加一些管理员信息如密码等(可以跳过)
后续 Jenkins URL 也跳过
点击 Start Using Jenkins 即可使用 Jenkins
