如何在GitLab ci中引用作业规则中的变量？ [英] How reference variables in job rules in gitlab ci?

问题描述

我需要重用GitLab配置项作业规则中的变量

include:
  - template: "Workflows/Branch-Pipelines.gitlab-ci.yml"

.staging_variables:
  variables:
    CONFIG_NAME: "staging"

.staging_rules:
  rules:
    - if: $CI_COMMIT_BRANCH == $STAGING_BRANCH
      variables: !reference [.staging_variables, variables]

stages:
  - staging

staging:
  stage: staging
  rules:
    - !reference [.staging_rules, rules]
  script:
    - echo $CONFIG_NAME
  tags:
    - staging

但是，我看到此Syntax is incorrect皮棉错误：

jobs:staging:rules:rule:variables config should be a hash of key value pairs

我使用的是这里解释的示例：

https://docs.gitlab.com/ee/ci/yaml/yaml_optimization.html#reference-tags

请注意，我可以做到这一点，并且它是有效的：

include:
  - template: "Workflows/Branch-Pipelines.gitlab-ci.yml"

.staging_rules:
  rules:
    - if: $CI_COMMIT_BRANCH == $STAGING_BRANCH
      variables:
          CONFIG_NAME: "staging"

stages:
  - staging

staging:
  stage: staging
  rules:
    - !reference [.staging_rules, rules]
  script:
    - echo $CONFIG_NAME
  tags:
    - staging

推荐答案

目前无法将!reference-关键字用于!reference引用节和!reference。

!reference documentation：

您不能重复使用已包含！Reference标记的节。仅限 支持一级嵌套。

根据您的需要，您可以使用YAML-Anchors。(未测试)

include:
  - template: "Workflows/Branch-Pipelines.gitlab-ci.yml"

.staging_variables: &staging_variables
  variables:
    CONFIG_NAME: "staging"

.staging_rules: &staging_rules
  rules:
    - if: $CI_COMMIT_BRANCH == $STAGING_BRANCH
      variables: *staging_variables

stages:
  - staging

staging:
  stage: staging
  rules:
    - *staging_rules
  script:
    - echo $CONFIG_NAME
  tags:
    - staging
