Jenkins入门

前言：

本套教程均全部使用容器来部署，传统部署请自行搜索。

运行环境：

CentOS Linux release 7.6.1810 (Core)
Docker Version:    18.09.9
可正常访问互联网
关闭防火墙和selinux

Jenkins 容器部署

我们下载LTS版本

LTS是长期支持版本

docker run --name devops-jenkins --user=root -p 8080:8080 -p 50000:50000 -v /opt/data/jenkins_home:/var/jenkins_home  -v /var/run/docker.sock:/var/run/docker.sock -v /usr/local/bin/docker:/usr/bin/docker -d jenkins/jenkins:lts

启动一个名为devops-jenkins的容器

它的用户名为root

将宿主机8080端口与容器内部8080映射

我们将Jenkins相关配置文件挂载出来方便修改

Jenkins 配置代理

更改代理地址

进入Jenkins安装目录

编辑hudson.model.UpdateCenter.xml 文件

将其改成

<?xml version=‘1.1‘ encoding=‘UTF-8‘?>
<sites>
  <site>
    <id>default</id>
    <url>https://updates.jenkins-zh.cn/update-center.json</url>
  </site>
</sites>

配置密钥

需要配置对应密钥

进入

cd war/WEB-INF/update-center-rootCAs/
删除文件夹内密钥文件
rm -rf *

在文件内创建一个名为mirror-adapter.crt密钥文件

密钥文件写入以下内容

-----BEGIN CERTIFICATE-----

重启Jenkins即可正常安装插件

Jenkins 添加节点(静态)

进入节点管理

进入管理页面后

点击新建节点

填写节点名称

填写Node相关信息

获取token

我获取到的secret-token

-secret c479f0044b37421ab5576580b774d3e3469ba971758956526b86300c7359f141

添加容器节点

我们需要以下镜像

https://hub.docker.com/r/jenkins/jnlp-slave

官方给出在linux运行jenkins-agent命令

docker run --init jenkins/inbound-agent -url http://jenkins-server:port <secret> <agent name>

Note: --init is necessary for correct subprocesses handling (zombie reaping)

初始化镜像要添加--init为了防止僵尸进程

运行命令：

docker run --init jenkins/jnlp-slave -url http://39.100.134.17:8080 -workDir=/opt/java c479f0044b37421ab5576580b774d3e3469ba971758956526b86300c7359f141 build

运行结果

最后看到Connected基本上连接成功了

出现问题请查看端口8080与50000端口是否放行

目前是前台输出我们把它放入后台容器中执行

docker run -dit jenkins/jnlp-slave -url http://39.100.134.17:8080 -workDir=/opt/java c479f0044b37421ab5576580b774d3e3469ba971758956526b86300c7359f141 build

查看节点页面是否正常连接

Jenkins 添加节点(动态)

首先需要先安装Docker插件

https://plugins.jenkins.io/docker-plugin/

或在jenkins插件管理中搜索Docker插件并安装

docker开启API远程访问

https://blog.csdn.net/longzhanpeng/article/details/82217398

#vim /usr/lib/systemd/system/docker.service
* * * * 省略
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
* * * * 省略

重启加载Docker

systemctl daemon-reload

systemctl restart docker

测试一下

curl http://localhost:2375/version

设置一些腾讯云或阿里云的安全策略和防火墙
