Azure Pipelines YAML:意外值“变量" [英] Azure Pipelines YAML: Unexpected value 'variables'

问题描述

我将Azure Pipelines用作Azure DevOps的一部分.我正在尝试在模板文件中定义变量，因为我需要多次使用相同的值.

I'm using Azure Pipelines as a part of Azure DevOps. I'm trying to define variables in my template file, because I need to use the same value multiple times.

这是我的 stage-template.yml :

parameters:
 - name: param1
   type: string
 - name: param2
   type: string

variables:
  var1: path/${{ parameters.param2 }}/to-my-file.yml

stages:
 - stage: Deploy${{ parameters.param2 }}
   displayName: Deploy ${{ parameters.param1 }}
   jobs:  
    ...

尝试使用此管道时，出现错误消息:

When trying to use this pipeline, I get an error message:

/stage-template.yml(第7行，第1行):意外值变量"

/stage-template.yml (Line: 7, Col: 1): Unexpected value 'variables'

为什么这不起作用?我做错了什么?

Why is this not working? What did I do wrong?

推荐答案

您不能在管道中有参数，只能在templateReferences中:

you cant have parameters in the pipeline, only in the templateReferences:

name: string  # build numbering format
resources:
  pipelines: [ pipelineResource ]
  containers: [ containerResource ]
  repositories: [ repositoryResource ]
variables: # several syntaxes, see specific section
trigger: trigger
pr: pr
stages: [ stage | templateReference ]

如果要在模板中使用变量，则必须使用正确的语法:

if you want to use variables in templates you have to use proper syntax:

parameters:
 - name: param1
   type: string
 - name: param2
   type: string

stages:
- stage: Deploy${{ parameters.param2 }}
  displayName: Deploy ${{ parameters.param1 }}
  variables:
    var1: path/${{ parameters.param2 }}/to-my-file.yml
  jobs:  
  ...
