使用 Azure Release Pipelines 以及 clustername、acr、resourcegroup 等参数将 Docker 映像部署到 AKS 集群

Question

我开始学习azure devops管道，尝试使用Azure Release Pipelines将Docker镜像部署到AKS集群中，例如：简单的python应用程序，创建docker镜像并使用动态用户输入参数将docker镜像部署到AKS集群中但图像参数值来自yml脚本中管道的值没有被选择。如果我错过了这里，请协助提供任何文档或语法，提前致谢！

该问题是由于您的 powershell 任务中的

'\${{ parameters.containerRegistry }}'

表达式不正确引起的。

要替换 powershell 任务中

azure-aks.yaml

中的图像字符串，我用以下方法修复了该任务：

          - task: PowerShell@2
            inputs:
              targetType: 'inline'
              script: |
                $aksYamlPath = "/home/vsts/work/1/drop/azure-aks.yaml"
                $containerRegistry = "${{ parameters.containerRegistry }}.azurecr.io"
                $content = Get-Content -Path $aksYamlPath -Raw
                $content = $content -replace '\$\{\{ parameters\.containerRegistry \}\}', $containerRegistry        # fix the expression
                Set-Content -Path $aksYamlPath -Value $content
                cat $aksYamlPath
            displayName: 'Replace Container Registry in YAML'

我在最后添加了

cat $aksYamlPath

来检查yaml内容，我的管道结果：
