docker安装gitlab并部署CICD

摘要

本文主要实现了在docker下安装gitlab，将gitlab绑定在宿主机的180端口，将gitlab的clone的URL添加指定端口号；部署了CI/CD，并公布了测试项目。

安装docker^[1]

1. 删除旧版本的docker（如果未安装则忽略）

sudo apt-get remove docker docker-engine docker.io containerd runc

2. 安装依赖

   sudo apt-get update
   sudo apt-get install \
       apt-transport-https \
       ca-certificates \
       curl \
       gnupg-agent \
       software-properties-common
   

3. Add Docker’s official GPG key

   curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
   

4. 添加仓库

   # x86_64
   sudo add-apt-repository \
      "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
      $(lsb_release -cs) \
      stable"
   
   # armf
   sudo add-apt-repository \
      "deb [arch=armhf] https://download.docker.com/linux/ubuntu \
      $(lsb_release -cs) \
      stable"
   
   # arm64
   sudo add-apt-repository \
      "deb [arch=arm64] https://download.docker.com/linux/ubuntu \
      $(lsb_release -cs) \
      stable"
   

5. 安装

   sudo apt-get update
   sudo apt-get install docker-ce docker-ce-cli containerd.io
   

docker换源

1. 注册阿里云账号

2. 选择容器镜像服务

3. 

4. 执行命令

   sudo mkdir -p /etc/docker
   sudo tee /etc/docker/daemon.json <<-'EOF'
   {
     "registry-mirrors": ["https://uy81mm79.mirror.aliyuncs.com"]
   }
   EOF
   sudo systemctl daemon-reload
   sudo systemctl restart docker
   

docker安装gitlab^{[2] [3]}

创建运行目录

sudo mkdir /opt/gitlab_docker
cd /opt/gitlab_docker

安装docker-compose

sudo apt install docker-compose

编写docker-compose.yml

version: '3.1'
services:
 gitlab:
  image: 'gitlab/gitlab-ce'
  container_name: "gitlab"
  restart: always
  privileged: true
  hostname: 'gitlab'
  environment:
   TZ: 'Asia/Shanghai'
   GITLAB_OMNIBUS_CONFIG: |
    external_url 'http://192.168.2.157:180'
    gitlab_rails['time_zone'] = 'Asia/Shanghai'
    gitlab_rails['smtp_enable'] = true
    gitlab_rails['gitlab_shell_ssh_port'] = 22
    nginx['listen_port'] = 180
    unicorn['port'] = 181
  ports:
   - '181:80'
   - '180:180'
   - '1443:443'
   - '22:22'
  volumes:
   - /opt/gitlab_docker/config:/etc/gitlab
   - /opt/gitlab_docker/data:/var/opt/gitlab
   - /opt/gitlab_docker/logs:/var/log/gitlab

安装gitlab镜像

sudo docker-compose up -d

修改文件配置

sudo vim /opt/gitlab_docker/config/gitlab.rb

1. 修改nginx['listen_port']

   nginx['listen_port'] = 180
   

2. 修改external_url

   external_url 'http://192.168.196.1:180'
   

3. 重新启动

   sudo docker exec -it $CONTINER_ID gitlab-ctl restart
   

CI/CD依赖

使用docker安装gitlab-runner也是可以的，但是感觉有bug，可能会不成功，这里介绍了我成功的方法。

安装gitlab-runner

找到对应包下载安装。下载地址https://gitlab-runner-downloads.s3.amazonaws.com/latest/index.html.

sudo dpkg -i gitlab-runner_amd64.deb

启动运行gitlab-runner

# 允许开机自启动
systemctl enable gitlab-runner
# 启动服务
systemctl start gitlab-runner

项目测试

创建项目

新建项目，项目文件如下：

.gitlab-ci.yml

# This file is a template, and might need editing before it works on your project.
# use the official gcc image, based on debian
# can use verions as well, like gcc:5.2
# see https://hub.docker.com/_/gcc/
image: ubuntu:bionic

build:
  stage: build
  # instead of calling g++ directly you can also use some build toolkit like make
  # install the necessary build tools when needed
  # before_script:
  #   - apt update && apt -y install make autoconf
  script:
    - g++ hello.cpp -o mybinary
  artifacts:
    paths:
      - mybinary
      # depending on your build setup it's most likely a good idea to cache outputs to reduce the build time
      # cache:
      #   paths:
      #     - "*.o"

# run tests using the binary built before
test:
  stage: test
  script:
    - chmod +x runmytests.sh
    - ./runmytests.sh

hello.cpp

#include <iostream>
using namespace std;
int main()
{
    cout << "hello world" << endl;
    return 0;
}

runmytests.sh

./mybinary

项目文件说明

.gitlab-ci.yml就是自动化测试的配置文件，相关内容可参见^[4]，建议大家仔细阅读该配置文件即可理解该项目。

gitlab-runner注册

查找api

注册

执行命令：

sudo gitlab-runner register

输入相关参数，下面内容引用自^[2:1]

# 输入 GitLab 地址
Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com/):
http://192.168.199.109/
 
# 输入 GitLab Token
Please enter the gitlab-ci token for this runner:
1Lxq_f1NRfCfeNbE5WRh
 
# 输入 Runner 的说明
Please enter the gitlab-ci description for this runner:
可以为空
 
# 设置 Tag，可以用于指定在构建规定的 tag 时触发 ci
Please enter the gitlab-ci tags for this runner (comma separated):
deploy
 
# 这里选择 true ，可以用于代码上传后直接执行（根据版本，也会没有此选项）
Whether to run untagged builds [true/false]:
true
 
# 这里选择 false，可以直接回车，默认为 false（根据版本，也会没有此选项）
Whether to lock Runner to current project [true/false]:
false
 
# 选择 runner 执行器，这里我们选择的是 shell
Please enter the executor: virtualbox, docker+machine, parallels, shell, ssh, docker-ssh+machine, kubernetes, docker, docker-ssh:
shell

重启gitlab-runner

systemctl restart gitlab-runner

自动测试

此时，应该是已经自动进行了测试了：
