Jenkins+docker +net core 3.1 实现自动化部署

 

基于docker 安装Jenkins

1. 拉取jenkins

   docker pull jenkins/jenkins

2. 启动docker容器

   mkdir /usr/local/jenkins
   chown -R 1000:1000 /usr/local/jenkins
   sudo chown -R 1000:1000 /var/run/docker.sock
   ​
   docker run -itd -p 8080:8080 -p 50000:50000 --name myjenkins --privileged=true -v /usr/local/jenkins:/var/jenkins_home -v /usr/bin/docker:/bin/docker -v /var/run/docker.sock:/var/run/docker.sock jenkins/jenkins

 

3. 打开浏览器配置Jenkins

   http://118.24.51.65:8080/

4. 查看管理员密码

   docker logs myjenkins
   或
   进入myjenkins容器
   docker exec -it myjenkins bash

5. 安装推荐插件 （等待安装完成）

6. 配置管理员密码

7. 修改根目录(加速)

   1. /usr/local/jenkins/hudson.model.UpdateCenter.xml

      <sites>
      <site>
      <id>default</id>
      <url>http://mirror.xmission.com/jenkins/updates/update-center.json</url>
      </site>
      </sites>

   2. 等jenkins初始化完成后找到跟目录下面updates文件中default.json文件做如下修改 /usr/local/jenkins/updates

      sed -i 's/http:\/\/updates.jenkinsci.org\/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

   3. 重启jenkins

      docker restart myjenkins

8. Jenkins 系统管理-脚本命令行,执行指令,修改时间

   System.setProperty('org.apache.commons.jelly.tags.fmt.timeZone', 'Asia/Shanghai')  

9. 安装插件

   Publish Over SSH

10. 配置 进入系统管理-》系统设置 找到Publish Over SSH

11. 配置linux地址

12. 【源码管理】配置GIT地址

13. 【构建触发器】 选择轮询方式 * * * * * 表示每分钟轮询一次

14. 构建环境【Delete workspace before build starts】勾选 表示删除工作空间 、【Abort the build if it's stuck】 超时时间会终止

15. 构建shell命令（镜像跟容器名要小写）

    #!/bin/bash
    ​
    # 获取短版本号
    GITHASH=`git rev-parse --short HEAD`
    # 复制镜像到根目录
    cp WebApplication1/Dockerfile .
    ​
    # 容器名称
    AppName=webapplication1
    ​
    echo ---------------删除容器...------------------
    docker stop $AppName
    docker rm  -f $AppName
    echo ---------------删除镜像...------------------
    echo '>>>获取旧的镜像'
    IID=$(docker images |grep -E  "($AppName|none)" |  awk '{print $3}')
    echo $IID
    if [ "$IID" != "" ];then
    echo '>>>删除旧的镜像'
    docker rmi -f $IID
    fi
    echo ---------------Building Docker Image...------------------
    ​
    docker build -t $AppName:$GITHASH .
    ​
    echo ---------------Launching Container...------------------
    ​
    docker run --name $AppName -d -p 8005:80 $AppName:$GITHASH

 

清空多余的镜像（参考）

docker image prune  

 

docker 下拉asp.net core 所需要的镜像(防止超时)
