基于GitLab 的持续集成工具 GitLab Runner 在Docker 下的安装

 

传统的部署无法适应互联网开发的小步快跑,快速迭代,这里使用持续集成工具 GitLab Runner 自动化部署

一般来说,构建任务都会占用很多的系统资源 (譬如编译代码),而 GitLab CI 又是 GitLab 的一部分,如果由 GitLab CI 来运行构建任务的话,在执行构建任务的时候,GitLab 的性能会大幅下降。

GitLab CI 最大的作用是管理各个项目的构建状态,因此,运行构建任务这种浪费资源的事情就交给 GitLab Runner 来做。

因为 GitLab Runner 可以安装到不同的机器上,所以在构建任务运行期间并不会影响到 GitLab 的性能。

环境准备

  • 创建工作目录 /usr/local/docker/runner
  • 创建构建目录 /usr/local/docker/runner/environment
  • 下载 jdk-8u152-linux-x64.tar.gz 并复制到 /usr/local/docker/runner/environment
  • 下载 apache-maven-3.5.3-bin.tar.gz并复制到 /usr/local/docker/runner/environment
daemon.json

/usr/local/docker/runner/environment 目录下创建 daemon.json,用于配置加速器和仓库地址

{
  "registry-mirrors": [
    "https://registry.docker-cn.com"
  ],
  "insecure-registries": [
    "192.168.1.23:5000"
  ]
}

insecure-registries 是 Docker 私服的地址

Dockerfile

/usr/local/docker/runner/environment 目录下创建 Dockerfile
自动化部署需要 maven,而 maven 又依赖于 JDK

WORKDIR /
docker-compose.yml

/usr/local/docker/runner 目录下创建 docker-compose.yml
表示从 environment 目录下寻找 Dockerfile,即在Docker 里装 Docker

version: '3.1'
services:
  gitlab-runner:
    build: environment
    restart: always
    container_name: gitlab-runner
    privileged: true
    volumes:
      - ./config:/etc/gitlab-runner
      - /var/run/docker.sock:/var/run/docker.sock

构建镜像并启动

/usr/local/docker/runner 目录下执行 docker-compose build
等待安装即可,中间有个从 GitHub 拉取 docker-compose 的环节可能比较慢,可以从官网或网页端下载放入目录下,修改Dockefile 从本地安装即可

注册 Runner

首先打开 GitLab ,进入持续集成设置界面,我这里是群组
在这里插入图片描述

启动容器后,用以下方式进入容器自动执行注册流程:

docker exec -it gitlab-runner gitlab-runner register

在交互式终端中填入 Git Lab 提供的 URL 和 token
如下所示:

root@environment:/usr/local/docker/runner# docker exec -it gitlab-runner gitlab-runner register
Runtime platform                                    arch=amd64 os=linux pid=12 revision=5a147c92 version=11.11.1
Running in system-mode.                            
                                                   
Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com/):
http://192.168.1.21/
Please enter the gitlab-ci token for this runner:
kTx_PUnx_hhy63pNJtqM
Please enter the gitlab-ci description for this runner:
[c77b5e39a2a6]: 
Please enter the gitlab-ci tags for this runner (comma separated):

Registering runner... succeeded                     runner=kTx_PUnx
Please enter the executor: docker, shell, ssh, docker-ssh+machine, docker+machine, kubernetes, docker-windows, docker-ssh, parallels, virtualbox:
shell
Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded! 
root@environment:/usr/local/docker/runner# 

这里跳过了 description 与 tags ,tags表示什么时候触发,为空表示任何时候都触发,deploy表示部署时触发,下面是执行器,这里填入 shell

回到 GitLab ,可以看到已经注册成功
