6、pipline 类型及触发方式

流水线类型参考文档： https://docs.gitlab.cn/jh/ci/pipelines/pipeline_architectures.html

1、流水线类型：

1、基本流水线(按照job个阶段执行)

yaml 复制代码

stages:
	- install
	- lint-code
	- build
	- deploy

job_install:
  stage: install
  tags: 
    - test
  script:
    - npm install
    
job_lint_code:
  stage: lint-code
  tags: 
    - test
  script:
    - npm run eslint
  allow_failure: true

2、DAG流水线（有向无环图流水线）

关键词 needs

如果效率对您很重要，并且您希望一切都尽可能快地运行，则可以使用有向无环图（DAG）。使用 needs关键字定义作业之间的依赖关系。当系统知道您的作业之间的关系时，它可以尽可能快地运行所有内容，甚至在可能的情况下跳到后续阶段。

在下面的示例中，如果 build_a 和 test_a 比 build_b 和 test_b 快得多，即使 build_b 仍在运行，系统也会启动 deploy_a。

yaml 复制代码

stages:
  - build
  - test
  - deploy

image: alpine

build_a:
  stage: build
  script:
    - echo "This job builds something quickly."

build_b:
  stage: build
  script:
    - echo "This job builds something else slowly."

test_a:
  stage: test
  needs: [build_a]
  script:
    - echo "This test job will start as soon as build_a finishes."
    - echo "It will not wait for build_b, or other jobs in the build stage, to finish."

test_b:
  stage: test
  needs: [build_b]
  script:
    - echo "This test job will start as soon as build_b finishes."
    - echo "It will not wait for other jobs in the build stage to finish."

deploy_a:
  stage: deploy
  needs: [test_a]
  script:
    - echo "Since build_a and test_a run quickly, this deploy job can run much earlier."
    - echo "It does not need to wait for build_b or test_b."

deploy_b:
  stage: deploy
  needs: [test_b]
  script:
    - echo "Since build_b and test_b run slowly, this deploy job will run much later."

3、父子流水线

关键词 trigger: include

使用场景：项目和使用文档是分离的，在部署项目的同时，也要更新使用文档

yaml 复制代码

stages:
  - triggers

trigger_a:
  stage: triggers
  trigger:
    include: a/.gitlab-ci.yml
  rules:     # 就是修改变动a下面的文件，就会触发这个 a下面的这个.yml, 不会执行trigger_b
    - changes:
        - a/*

trigger_b:
  stage: triggers
  trigger:
    include: b/.gitlab-ci.yml
  rules:
    - changes:
        - b/*

4、多项目流水线

使用场景：比如微前端，需要同时部署几个子应用

yaml 复制代码

trigger:
	stage: deploy
	trigger:
		project: root/minapp  #指向的其他应用项目
		branch: master
		stragegy: depend   #子流水线的状态会在父流水线显示出来

5、合并请求流水线

yaml 复制代码

build_a:
  stage: build
  script:
    - echo "This job builds something quickly."
	only:
		- merge_requests

2、流水线的触发

1、推送代码

2、定时触发

注释：自定义时间： 21: 分钟 17：小时 15: 天数 10: 月份 *：每月

3、url 触发

场景：（使用机器人 or 发布平台）

curl

bash 复制代码

curl -X POST \
--fail \
-F token=TOKEN \
-F ref=REF_NAME \
http://gitlab.21silva.top:8090/api/v4/projects/3/trigger/pipeline

webhook （群机器人）

bash 复制代码

http://gitlab.21silva.top:8090/api/v4/projects/3/ref/REF_NAME/trigger/pipeline?token=TOKEN

4、手动

yaml 复制代码

job_deploy_main:
	stage: deploy
	image: docker
	tags: 
	- test
	script:
	- docker build -t testimageprod .
	- if [ $(docker ps -aq --filter name=mycicd-containerprod) ]; then docker rm -f mycicd-containerprod;fi
	- docker run -d -p 8082:80 --name mycicd-containerprod testimageprod
	environment:
		name: silvaProd
		url: 访问url
	only:
	- main
	when: manual
