gitlab的持续集成

参考链接：gitlab-ci + docker配置 基于Gitlab-CI/CD Docker 持续集成 node 项目

介绍

CI/CD(Continus Integration/Continues Delivery)持续集成 GitLab提供了一种通过Docker和Shared Runners处理CI/CD Pipeline的简单方法。每次运行Pipeline时，GitLab都会创建一个独立的虚拟机并构建一个Docker镜像。Pipeline可以使用YAML配置文件进行配置。

目的

  • 代码提交gitlab，自动触发构建
  • gitlab发起Merge Request, 进行自动化测试（至少是单元测试），通过后才可以merge，实现代码review和质量管控
  • gitlab开发分支merge后自动发布到test环境
  • gitlab master分支merge后自动发布到prod环境

启动GitLab runner服务

基于Gitlab-CI/CD Docker 持续集成 node 项目

配置

项目中新建.gitlab.ci.yml文件（gitlab-ci.yml配置参数参照 ），构建阶段为build -> test -> deply

stages:
  - build
  - test
  - deploy

variables:
  # 内置环境变量 https://docs.gitlab.com/ee/ci/variables/
  # $DOCKER_USERNAME $DOCKER_PWD 在settings CI/CD中的Secret variables配置，如果是protected表示保护分支有效
  DEV_TAG: dev_$CI_COMMIT_SHA
  PROD_TAG: prod_$CI_COMMIT_SHA
  REPO: dockerhub.datagrand.com/datagrand/jianxin-client

before_script:
  - docker login -u $DOCKER_USERNAME -p $DOCKER_PWD http://dockerhub.datagrand.com
  - echo 'commit id full:' $CI_COMMIT_SHA
  - echo 'commit user:' $GITLAB_USER_NAME

# develop
build:
  stage: build
  script:
    - sh build/build.sh $REPO $DEV_TAG
  allow_failure: false

# test
test:
  stage: test
  script:
    - sh build/test.sh $REPO:$DEV_TAG
  allow_failure: false
  dependencies:
    - build

# production
deploy:
  stage: deploy
  when: manual
  only:
    - master
  script:
    - sh build/deploy.sh $REPO:$PROD_TAG
  allow_failure: false
  dependencies:
    - test

build.sh

#!/bin/bash

echo '开发环境打包 >>>' $1:$2

# 构建镜像
docker build -t $1:$2 -f build/Dockerfile .

# 推送镜像
docker push $1:$2

deploy.sh

echo '开始发布到生产环境 >>>' $1
docker pull $1
