Azure Pipelines : Variable not taking assigned value, 相反解析为 $(variableName)

Question

我正在使用 Azure Pipelines，并遇到使用 ##vso[task.setvariable] 语法设置管道变量的问题。我的目的是根据管道中的环境参数设置变量 kaasServiceConnection 不同的值。但是，当我稍后在管道中引用该变量时，它似乎并未获取指定的值；相反，它似乎解析为 $(kaasServiceConnection)。

这是我的管道中的相关片段:

- script: |
    if [ "$(parameters.environment)" == "dev" ]; then
      echo "##vso[task.setvariable variable=kaasServiceConnection;]SVC-DEV-CONN"
    elif [ "$(parameters.environment)" == "qa" ]; then
      echo "##vso[task.setvariable variable=kaasServiceConnection;]SVC-QA-Conn"
    fi
  displayName: 'getting Service Connection'

- task: HelmDeploy@0
  displayName: 'Helm upgrade'
  inputs:
    connectionType: 'Kubernetes Service Connection'
    kubernetesServiceEndpoint: '$(kaasServiceConnection)'
    ...

我认为这适合您的情况，并且更适合 azure DevOps 管道。

变量部分也接受表达式，请参阅 conditionally-assign-a-variable

parameters:
 - name: environment
   type: string
   values:
    - dev
    - prod
variables:
- ${{ if eq(parameters.environment, 'dev') }}:
    - name: kaasServiceConnection
      value: "SVC-DEV-CONN"
- ${{ if eq(parameters.environment, 'qa') }}:
    - name: kaasServiceConnection
      value: "SVC-QA-CONN"

stages:
  - stage: yourStage
    steps:
      - task: HelmDeploy@0
        displayName: 'Helm upgrade'
        inputs:
          connectionType: 'Kubernetes Service Connection'
          kubernetesServiceEndpoint: $(kaasServiceConnection)

Please adjust the pipeline accordingly.
