如何搭建基于Docker的gitlab服务器集成CI/CD实现DEVOPS(完整版)

From this lesson you will learn about

1,How to install and configure a docker based gitlab server

2,How to install and configure a docker based seperated gitlab-runner

3,The basic usage of expect utility

4,How to trigger a script task when committing files to gitlab server

5,How to map a local folder to a container folder

#从本课程你将学会

1,怎样安装和配置一个基于docker的gitlab server

2,怎样安装和配置一个基于docker的单独的gitlab-runner

3,expect 工具的基本使用

4,怎样在提交文件时触发gitlab server的脚本任务

5,怎样映射本地文件夹到容器文件夹

The configuration directory of gitlab server(in container)(gitlab server在容器中的配置目录)

/etc/gitlab   #gitlab configuration directory(配置文件目录)

/var/log/gitlab  #gitlab log directory (日志目录 )

/var/opt/gitlab #gitlab data directory(数据目录)

The gitlab server related ports:443,80,22

环境：CentOS7 ,Docker CE

1，Pull the gitlab image（拉取gitlab镜像）

sudo docker pull gitlab/gitlab-ce

2，

Prepare gitlab local foldders (准备gitlab本地文件夹)

sudo mkdir /home/gitlab
sudo chmod -Rf  /home/gitlab
sudo cd /home/gitlab
sudo mkdir etcgitlab
sudo mkdir loggitlab
sudo mkdir optgitlab

3，Create a docker  network （创建一个docker网络）

sudo docker network create --attachable --driver overlay my-net-git 

#--attachable ,can be manually attached (可被手动附加)

#--overlay   , can support Docker Swarm network (可支持Docker Swarm集群网络)

4，Run the gitlab server (运行gitlab server镜像)

 sudo docker run -td  -p : -p : -p : --name gitlab --restart always \

--network my-net-git  -v /home/gitlab/etcgitlab:/etc/gitlab -v /home/gitlab/loggitlab:/var/log/gitlab -v /home/gitlab/optgitlab:/var/opt/gitlab gitlab/gitlab-ce

#--network my-net-git let the gitlab container join the network my-net-git(让容器加入到my-net-git网络)

#-p ,host port to container port mapping (主机到容器的端口映射)

5，Prepare gitlab-runner Dockerfile

sudo mkdir docker
sudo chmod  docker
sudo vi docker/Dockerfile

Copy below content to the file

FROM centos:6.10

MAINTAINER Liping

RUN bash -c "curl -L https://packages.gitlab.com/install/repositories/runner/gitlab-runner/script.rpm.sh | bash"

RUN bash -c  "yum install -y expect.x86_64 expect-devel.x86_64"

RUN bash -c "yum install -y gitlab-runner"

ADD ./docker/my-init.sh /home/sh/my-init.sh

RUN chmod  /home/sh/my-init.sh

CMD ["/home/sh/my-init.sh"]

6，Open your gitlab server url ,the first access will ask you to set a new password.

Navigate to http://localhost:9080/admin/runners

Find the Server URL and to Token for Runner Registration.

打开gitlab server url,首次访问时会要求设置一个新密码。导航到http://localhost:9080/admin/runners

查找图所示 的url 和token 用于Runner 注册.

7，Prepare the Runner Registration script (准备Runner的注册脚本)

sudo vi docker/my-init.sh

Copy content below to the file replace the red font portion to your own data(复制如下内容至文件，使用你自己第7步中查到的数据，替换红色字体部分)

#!/usr/bin/expect

#the gitlab runner init command(gitlab runner 的初始化命令)

spawn gitlab-runner register --locked=false

expect "*gitlab.com/):"

#input the gitlab server url ,replace with your real gitlab server url(输入gitlab 服务>器地址,使用你实际的gitlab server地址代替)

send "http://localhost:9080/\r"

expect "*token for this runner:"

#replace with your real token

send "FSrjiy8_9oDbst2-xX-S\r"

expect "*description for this runner:*"

send "myrunner\r"

expect "*tags for this runner (comma separated):*"

send " \r"

expect "*shell,*"

send "shell\r"

exec bash -c "service gitlab-runner restart"

exec bash -c "read"

8，

sudo docker build -t lipingsg/mygitrunner -f docker/Dockerfile .

9，Start the gitlab-runner container (启动gitlab-runner容器)

sudo docker run -td --name my_gitrunner  --network my-net-git  lipingsg/mygitrunner 

10，Go to the gitlab server url http://localhost:9080/admin/runners , verify the registration was done.

导航至http://localhost:9080/admin/runners 验证注册是否已完成。

11，Go to http://localhost:9080/admin/application_settings/ci_cd

Uncheck “Default to Auto DevOps pipeline for all projects”and save.

进入ci_cd 页面 取消“Default to Auto DevOps pipeline for all projects”并保存

12,Create a new Project in gitlab ,and create a .gitlab-ci.yml to test the trigger fuction for a script task.（创建一个新工程，在工程中创建一个 .gitlab-ci.yml 文件 用来测试自动触发脚本任务是否完成） .gitlab-ci.yml的内容如下

stages:
  - test
  - build
  - deploy
job 1:
  stage: test
  script:
      - echo "$(date +"%Y%m%d%H%M%S")" job 1 done
job 2:
  stage: build
  script:
      - echo "$(date +"%Y%m%d%H%M%S")" job 2 done
job 3:
  stage: deploy
  script:
      - echo "$(date +"%Y%m%d%H%M%S")" job 3 done

13,The gitlab server DEVOPS environment is working.

Gitlab 服务器的DEVOPS功能已经完成，如果有任何疑问请在下面提出~
