gitlab-ci.yml, before_script 和神器

Question

在gitlab-ci.yml documentation中说

before_script is used to define the command that should be run before all jobs, including deploy jobs, but after the restoration of artifacts.

这告诉我工件是在作业开始之前生成的 运行

但是 artifact documentation 说

Artifacts is a list of files and directories which are attached to a job after it completes successfully

这告诉我工件是在作业完成后生成的 运行。

这是矛盾的。谁能解释一下这怎么不矛盾？

我猜他们是在谈论上一份工作中的神器？但我不知道神器和工作是如何工作的，并且可能是错误的。

Answer 1

工件可以由一个阶段的构建作业生成，并由下一阶段的构建作业使用。因此 before_script 是 运行 在为当前阶段恢复前一阶段产生的工件之后。

所以下面的.gitlab-ci.yml

stages:
  - build
  - test

before_script:
  - echo "before_script"
  - ls

build_artifacts:
  stage: build
  tags:
    - docker
  script:
    - echo "build_artifacts"
    - touch build_output
  artifacts:
    paths:
      - build_output

test_artifacts:
  stage: test
  tags:
    - docker
  script:
    - echo "test_artifacts"

将给出以下输出：

# build_artifacts job
$ echo "before_script"
before_script
$ ls
README.md
$ echo "build_artifacts"
build_artifacts
$ touch build_output
Uploading artifacts...
build_output: found 1 matching files               
Uploading artifacts to coordinator... ok            id=56026 responseStatus=201 Created token=xxxxzzzz
Job succeeded



# test_artifacts job
Downloading artifacts for build_artifacts (56026)...
Downloading artifacts from coordinator... ok        id=56026 responseStatus=200 OK token=xxxxzzzz
$ echo "before_script"
before_script
$ ls
README.md
build_output
$ echo "test_artifacts"
test_artifacts
Job succeeded

如您所见，test_artifacts 作业在 before_script 运行 之前下载工件。
