Azure Pipeline 部署到 Kubernetes:覆盖图像参考

Azure Pipline Deploy to Kubernetes: Override image reference

我有一个包含一个容器的 deployment.yml 文件,如下所示:

apiVersion: apps/v1
kind: Deployment
[...]
    spec:
      containers:
        - name: my-app
          image: acr/my-app:1.0 #-> should be completly overridden!

和一个 Azure DevOps 作业,它做一个停靠 build/push 并且应该部署我的应用程序:

variables:
  imageRepository: 'my-app'
  containerRegistry: 'acr'
  dockerfilePath: '$(Build.SourcesDirectory)/myapp/Dockerfile'
  tag: '$(Build.BuildId)'

[...]

- task: KubernetesManifest@0
      displayName: Deploy on kubernetes cluster
      inputs:
        action: 'deploy'
        kubernetesServiceConnection: '...'
        namespace: 'default'
        manifests: '$(Build.SourcesDirectory)/deployment.yml'
        containers: |
          $(containerRegistry)/$(imageRepository):$(tag)

我想覆盖 deployment.yml 中的完整图像参考值。但我不知道如何编写工作占位符。我尝试了很多不同的东西,从 $(VALUE)VALUE 到 ``{{ VALUE }} ,例如:

image: ${{ variables.containerRegistry }} / ${{ variables.imageRepository }} : ${{ variables.tag}}。但是占位符根本没有被替换,并且 Pod 因无效图像引用而失败。

Azure DevOps 可以做到这一点,还是我需要通过 bash 任务或类似的方式覆盖图像值?

更新

澄清我的要求: 我想覆盖完整的字符串,因为我想在多个阶段重用该文件,其中只有注册表标签很困难。例如:acr1/my-app:tag1acr2/my-app:tag2

取自https://docs.microsoft.com/en-us/azure/devops/pipelines/tasks/deploy/kubernetes-manifest?view=azure-devops

The fully qualified URL of the image to be used for substitutions on the manifest files. This input accepts the specification of multiple artifact substitutions in newline-separated form. Here's an example:

containers: |
  contosodemo.azurecr.io/foo:test1
  contosodemo.azurecr.io/bar:test2

In this example, all references to contosodemo.azurecr.io/foo and contosodemo.azurecr.io/bar are searched for in the image field of the input manifest files. For each match found, the tag test1 or test2 replaces the matched reference.

您需要确保清单中的字符串与 KubernetesManifestTask

中的 registry/image:tag 字符串匹配

Azure DevOps 填充 wine 匹配 registry/image 并更新标签部分
