在azure管道中替换yml文件中的变量

Question

我在azure流水线上声明变量，并希望将它们注入到deployment.yml文件中，使用replacetoken@4任务来实现这一点，但变量不会使用vaules更新。

管道代码: azure-pipelines.yaml

  stages:
  - stage: dockerbuild
  variables:
  - name: replicas
    value: 2
  jobs:
  - job: builddockerimageandpush
    pool: 
    name: Azure Pipelines
    steps:
        
      - task: Bash@3
        inputs:
        targetType: 'inline'
        script: |
          COMMAND="$(echo '$(build.sourceversion)' | cut -c-7)"
          echo "##vso[task.setvariable variable=dockertag]$COMMAND"
      displayName: GetCommitID
      
    
      - task: replacetokens@4
        inputs:
          rootDirectory: '$(System.DefaultWorkingDirectory)'
          targetFiles: 'deployment.yaml'
          encoding: 'auto'
          tokenPattern: 'default'
          writeBOM: true
          actionOnMissing: 'warn'
          keepToken: false
          actionOnNoFiles: 'continue'
          enableTransforms: false
          useLegacyPattern: false
          enableTelemetry: true

下面是deployment.yaml配置

apiVersion: apps/v1
kind: Deployment
metadata:
  name: messagesender
  labels:
  app: messagesender
spec:
  selector:
    matchLabels:
      app: messagesender
replicas: {replicas}
template:
  metadata:
    labels:
      app: messagesender    
  spec:
    containers:
    - name: devcontainer
      image: telefonicamdnidevcontainer.azurecr.io/messagesender:{dockertag}
      imagePullPolicy: Always

因此，在上面的配置变量{replicas}和{dockertag}需要替换，但这并没有发生。有没有人能帮我看看这里少了什么。提前感谢

默认的令牌模式是#{some_variable_here}#。在你的deployment.yml中，它就是{some_variable}。

将其更改为#{replicas}#和#{dockertag}#。

apiVersion: apps/v1
kind: Deployment
metadata:
  name: messagesender
  labels:
  app: messagesender
spec:
  selector:
    matchLabels:
      app: messagesender
replicas: #{replicas}#
template:
  metadata:
    labels:
      app: messagesender    
  spec:
    containers:
    - name: devcontainer
      image: telefonicamdnidevcontainer.azurecr.io/messagesender:#{dockertag}#
      imagePullPolicy: Always
