用docker-compose 部署 Jenkins + Gitlab 环境快速自动部署 SpringBoot项目

提示：以下是本篇文章正文内容，下面案例可供参考

一、CI/CD是什么？

二、使用步骤

1.安装docker

下载地址：https://mirrors.tuna.tsinghua.edu.cn/docker-ce/
代码如下（示例）：

    1.解压安装包
        tar -zxvf docker.**.tgz
    2.将文件移动到/usr/bin/文件夹下
        cp ../docker/* /usr/bin/
    3.在/etc/systemd/system/创建docker.service(文件内容见2.1)
        cd /etc/systemd/system
        touch docker.service
        vi docker.service
        .... (见下面1.1)
    4.赋文件权限和启动docker
        chmod +x docker.service    # 添加文件权限
        systemctl daemon-reload    # 重载unit配置文件
        systemctl start docker     # 启动docker
        systemctl enable docker.service #设置开机自启
        (
            设置开机自启出错：Failed to execute operation: File exists
            解决部分：find / -name docker.service
            rm 删除除自己添加外相同名称的配置文件
        )

# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker

# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.

# Uncomment TasksMax if your systemd version supports it.
# Only systemd 226 and above support this version.
#TasksMax=infinity

3.2 配置容器信息

创建docker-compose.yml文件，配置jenkins信息

version: '3.1'
networks: # 网关配置
  docker_net:
     driver: bridge
     ipam:
       driver: default
       config:
         - subnet: 172.66.11.0/24
services:
  jenkins:
     restart: always
     image: jenkins/jenkins
     container_name: jenkins
     user: root
     ports:
      - '8080:8080' # 浏览器访问端口
      - '50000:50000'
     volumes:
      - /usr/local/maven/:/usr/local/maven   # 将本地maven映射到jenkins容器中去
      - /root/docker/jenkins/jenkins_home:/var/jenkins_home # 将容器中的jenkins数据映射到服务器
      - /usr/bin/docker:/usr/bin/docker
      - /var/run/docker.sock:/var/run/docker.sock
     networks:
       docker_net:
        ipv4_address: 172.66.11.19

docker-compose.yml文件，配置jenkins信息

  gitlab:
     restart: always
     image: twang2218/gitlab-ce-zh
     container_name: gitlab
     hostname: '192.168.14.102'
     ports:
      - '8443:443'
      - '8088:8088' # 浏览器访问端口
      - '8022:22'
     volumes:
      - /root/docker/config/gitlab:/etc/gitlab
      - /root/docker/logs/gitlab:/var/log/gitlab
      - /root/docker/data/gitlab:/var/opt/gitlab
     environment:
      TZ: 'Asia/shanghai'

vi /root/docker/config/gitlab/gitlab.rb

alertmanager['flags'] = {
  'cluster.advertise-address' => '127.0.0.1:9093'
}

4.配置Jenkins和Gitlab适用maven打包部署

配置jenkins 的工具

git和jdkjenkins时安装时就会有，所有直接配置容器中的安装路径


还需要安装maven打包项目，所以
下载maven 所需插件

服务器安装maven并映射到容器中去


接下来创建任务，


构建

总结
