gitlab-ci: 1.2.0 .gitlab-ci.yml 基础

12 Dec 2019

0. .gitlab-ci.yml说明

参考链接：.gitlab-ci.yml 官方文档 .gitlab-ci.yml是用于配置gitlab的pipeline，里面定义了

image: dind

stages:
  - build
  - docker-build

variables:
  DOCKER_HOST: unix:///var/run/docker.sock
  DOCKER_DRIVER: overlay2
  MAVEN_OPTS: -Dmaven.repo.local=${CI_PROJECT_DIR}/.m2

before_script:
  - docker login -u user -p password private.docker-registry.net

build:
  stage: build
  script:
    - mvn clean install ${MAVEN_OPTS}
  cache:
    paths:
      - ${CI_PROJECT_DIR}/.m2
  artifacts:
    paths:
      - target
    expire_in: 1 day

docker-build:
  stage: docker-build
  script:
    - docker build --cache-from private.docker-registry.net/web:latest
        -t private.docker-registry.net/web:${CI_COMMIT_SHA:0:6}
        -t private.docker-registry.net/web:latest .
    - docker push private.docker-registry.net/web:${CI_COMMIT_SHA:0:6}
  only:
    - master

注意点：

  • 只有一个stage里面的所有job都执行完毕了，才会去执行下一个stage
  • 同一个stage里面的job是同时被执行的
  • only限定了只有master分支commit后才会触发pipeline的执行

1. 常用的gitlab ci内置变量

2. 关于curl的用法

  script: >-
    curl -X POST -H "Content-Type:application/json" -H "Authorization: 认证字符串" -d "{\"extra_vars\": {\"role\": \"test_role\",\"project\": {\"version\": \"${CI_COMMIT_SHA:0:6}\",\"name\": \"project_name\"},\"host\": \"project_host\"}}" http://awx_domain/api/v2/job_templates/deploy_test/launch/

别问我为啥，我是尝试了很多形式才成功的，最终这样成功了 gitlab issues stackoverflow

另外一种简单方法

  script:
    - msg='{"extra_vars": {"role": "test_role","project": {"version": "'${CI_COMMIT_SHA:0:6}'","name": "project_name"},"host":"project_host"}}'
    - >
      curl -X POST -H "Content-Type:application/json" -H "Authorization: 认证字符串" -d ${msg} http://awx_domain/api/v2/job_templates/deploy_test/launch/

注意msg变量不能用空格，curl命令的json格式里面都不要有空格

3. 关于for循环中多行代码的写法

  script:
    - echo ${rsyncpass} > ./rsyncpass && chmod 600 ./rsyncpass
    - for ip in ${rsync_dest_all};
        do
          rsync -auvz --progress --no-o --no-g --no-p --delete
            --password-file=./rsyncpass
            --exclude="properties" --exclude="config.properties"
            --exclude="ftp.properties" --exclude="log4j.properties"
            ./demo/target/demo/* rsync@<ip>::<RSYNC_DEST_MOD_PREF>;
        done

失败的尝试是在rsync的多行命令末尾增加\

4. git strategy

通过设定GIT_STRATEGY，我们可以来给job设定不同的git策略

5. anchors

如果遇到需要复用的部分，可以使用anchors

.job_template: &java-project
  cache:
    paths:
      - ${PROJECT_CACHE}
  artifacts:
    paths:
      - ${PROJECT_ARTIFACTS}

javaproject01:
  <<: *java-project
  varibles:
    PROJECT_CACHE: .m2
    PROJECT_ARTIFACTS: ./target
  script:
    - test1 project

javaproject02:
  <<: *java-project
  varibles:
    PROJECT_CACHE: .m2
    PROJECT_ARTIFACTS: ./target
  script:
    - test2 project

gitlab ci yaml anchors

6. include

如果遇到多个project复用的部分逻辑，可以使用include

# 多个project都需要同样的before_script
# put it in https://gitlab.com/awesome-project/raw/master/.before-script-template.yml
before_script:
  - apt-get update -qq && apt-get install -y -qq sqlite3 libsqlite3-dev nodejs
  - gem install bundler --no-document
  - bundle install --jobs $(nproc)  "${FLAGS[@]}"

# 在另外一个.gitlab-ci.yml中
include:
  - 'https://gitlab.com/awesome-project/raw/master/.before-script-template.yml'
  - '/templates/.after-script-template.yml'
  - template: Auto-DevOps.gitlab-ci.yml
  - project: 'my-group/my-project'
    ref: master
    file: '/templates/.gitlab-ci-template.yml'
