如何将变量传递给azure yaml中的模板参数？

Question

我有模板

dockerbuild.yml

steps:
  - task: Bash@3
    displayName: Build an image to container registry
    inputs:
      script : echo $(PATH)

然后是一个变量文件

var.build.yml
- name: PATH
  value: 'docker/path'
- name: PATH1
  value: 'docker/oldpath'
- name: PATH2
  value: 'docker/newpath'

azurepipeline1.yml

resources:
  repositories:
  - repository: templates
    type: git
    name: components/pipeline_templates
trigger:
- none

pool:
  name: PoolA

variables:
- template: variabletemplates/var.build.yml@templates

jobs:
  steps:
      - template: CI-CD/dockerbuild.yml@templates  # Template reference  
        parameters:
          PATH: ${{ variables.PATH }}
      - template: CI-CD/dockerbuild.yml@templates  # Template reference  
        parameters:
          PATH: ${{ variables.PATH1 }}
      - template: CI-CD/dockerbuild.yml@templates  # Template reference  
        parameters:
          PATH: ${{ variables.PATH2 }}

上面的代码有效

但是如果我将参数更改为

    parameters:
      PATH: ${{ variables.PATH1 }}
       OR
    parameters:
      PATH: ${{ variables.PATH2 }}

在输出中它显示

 Output:
   docker/path
    $(PATH1)
    $(PATH2)

我需要在具有不同路径的管道中多次重用模板。请帮助解决问题

您的模板需要一个parameters块。

parameters:
  - name: PATH
    type: string

steps:
  - task: Bash@3
    displayName: Build an image to container registry
    inputs:
      script : echo ${{ parameters.PATH }}
