extends

在GitLab 11.3中引入

extends 定义使用扩展的作业将从中继承的条目名称。
在另一种情况下,使用YAML锚定更灵活和可读。

.tests:
  only:
    refs:
      - branches

rspec:
  extends: .tests
  script: rake rspec
  stage: test
  only:
    variables:
      - $RSPEC

多亏了这个问答 yaml repeated node that is a key

解决方案是:

.deploy_base:  &deploy_base
  stage: deploy
  tags:
  - linux
  retry: 2
  script:  &deploy_script
  - do_action 1
  - do_action 2
  - git push artifacts

deploy_release:
  only:  &deploy_release_only
  - master
  - stable
  script: *deploy_script

deploy_manual:
  except: *deploy_release_only
  when: manual
  script: *deploy_script

更妙的是:

.deploy_base :

.deploy_base: &deploy_base
  stage: deploy
  tags:
  - DlpcsCore
  - linux
  retry: 2
  variables:
    URL: 'git@gitlab.com:Yahoo/HeavenShine-bin.git'
  script: &deploy_script
  - do_act_1
  - do_action_2

deploy_release:
  << : *deploy_base
  only: &deploy_release_only
  - master
  - stable
  - CI
  #- /^master[-_].+$/
  #- /^(.+)[+]bin$/

deploy_manual:
  << : *deploy_base
  except: *deploy_release_only
  when: manual

YAML合并

Gitlab现在通过 rules https://docs.gitlab.com/ee/ci/yaml/#rules-clauses
