gitlab - 在 GitLab CI 中使用来自合并请求作业的工件

Question

在我的项目中，我使用合并请求来测试构建，并在提交合并到 master 后进行部署。目前我的 .gitlab-ci.yml好像:

build:
  stage: build
  script:
    - yarn build
  artifacts:
    paths:
      - public

deploy:
  stage: deploy
  script: yarn deploy
  rules:
    - if: $CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH

这种方式只会将构建成功的提交合并到 master 并部署。但是构建阶段运行两次，一次在合并请求分支中，一次在 master 中。我想要一些类似的东西:

build:
  stage: build
  script:
    - yarn build
  artifacts:
    paths:
      - public
  rules:
    - if: $CI_PIPELINE_SOURCE == "merge_request_event"

deploy:
  stage: deploy
  script: yarn deploy
  rules:
    - if: $CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH

但是部署作业应该有办法拉取由 build 生成的工件。合并请求分支中的作业。是否可以？

检查 CI_MERGE_REQUEST_REF_PATH 变量可用。
如果是这样，那么也许您可以将其与 GET /projects/:id/jobs/artifacts/:ref_name/download?job=name 一起使用API 调用，用于在合并请求的最近成功管道中下载您想要的作业的工件。
像这样的东西:

rules:
  - if: ${CI_PIPELINE_SOURCE} == "merge_request_event"
script:
    # Download the binaries from the most recent successful pipeline for the CI_MERGE_REQUEST_REF_PATH
    # See: https://docs.gitlab.com/ee/api/job_artifacts.html#download-the-artifacts-archive
    - echo Downloading ${CI_API_V4_URL}/projects/$(echo ${CI_PROJECT_PATH} | sed "s/\//%2F/g")/jobs/artifacts/$(echo ${CI_MERGE_REQUEST_REF_PATH} | sed "s/\//%2F/g")/download?job=build
    # Because of the ':' in the header, the whole curl command must be inside single-quotes
    - 'curl
       --header "JOB-TOKEN: ${CI_JOB_TOKEN}"
       --output ${CI_PROJECT_DIR}/artifacts.zip
       ${CI_API_V4_URL}/projects/$(echo ${CI_PROJECT_PATH} | sed "s/\//%2F/g")/jobs/artifacts/$(echo ${CI_MERGE_REQUEST_REF_PATH} | sed "s/\//%2F/g")/download?job=build'
    # extract desired artifacts from the zip file.
    - unzip
       -o
       -d ${CI_BUILDS_DIR}/${CI_PROJECT_NAMESPACE}
       ${CI_PROJECT_DIR}/artifacts.zip
       'directory/subDirectory/*'

注意 CI_PROJECT_PATH 和 CI_MERGE_REQUEST_REF_PATH 通常都包含 /人物。我用过 sed将它们更改为 URL 编码的 %2F .
