如何从不同的变量组 Azure Pipeline 访问相同的变量？

Question

I am using azure-pipelines.yaml to build multiple stages each stage having a same variable ie var_key but different value in each stage for this I have different Azure Library groups

1. dev_group
2. qa_group

azure-pipelines.yaml

name: $(Date:yyyyMMdd)$(Rev:.r)

pr:
  branches:
    include:
    - develop
    - master

trigger:
  branches:
    include:
    - develop
    - master

variables:
  group: group1, group2, group3
  BuildNumber: $(Build.BuildNumber)

stages:
  - stage: debug
    jobs:
      - job: DebugConditions
        pool: 
          vmImage: 'ubuntu-latest'
        steps:
          - bash: echo $(group1.var_key)

   - stage: dev
    jobs:
      - job: DevConditions
        pool: 
          vmImage: 'ubuntu-latest'
        steps:
          - bash: echo $(group2.var_key)

this is giving me an error, is there an correct way of doing this.

Answer 1

In the future, please refer to the YAML schema documentation before you ask a question about an error with YAML.

A quick review of that document shows that this:

variables:
  group: group1, group2, group3

is not correct syntax.

To include variable groups, switch to this sequence syntax:

 variables:
 - name: string  # name of a variable   value: string # value of the variable
 - group: string # name of a variable group You can repeat name/value pairs and group.

You can also include variables from templates.

Extrapolating from that,

variables:
- group: group1
- group: group2
- group: group3

Following the schema is critical when writing YAML configuration documents. It is whitespace sensitive, so be sure you are indenting properly. I recommend using an editor such as VS Code with the Azure Pipelines YAML extension installed to help catch problems like this.

Beyond that, to use a variable group only within a stage, you reference it within the stage block:

stages: 
- stage: Foo
  variables:
  - group: DEVgroup

Again, read the schema documentation. This is all very well documented.
