Azure Devops kubectl 任务部署的镜像的状态为 ErrImagePull/ImagePullBackOff

Question

我使用 Azure Devops 创建了一个部署管道，通过它构建镜像并将其推送到 Azure 容器注册表。在下一步中，我将从 ACR 部署到我使用以下命令创建并附加到 ACR 的 AKS 集群:az aks create -n HealthCareAKSCluster -g AKSCICDRG --generate-ssh-keys --attach-acr HealthCareAKSCICDACR以下是我的 yaml 代码:

# Docker
# Build and push an image to Azure Container Registry
# https://learn.microsoft.com/azure/devops/pipelines/languages/docker

trigger:
- master

resources:
- repo: self

variables:
  # Container registry service connection established during pipeline creation
  dockerRegistryServiceConnection: 'XXXXXXXXXX'
  imageRepository: 'patientservice'
  containerRegistry: 'healthcareakscicdacr.azurecr.io'
  dockerfilePath: './PatientService/Dockerfile'
  tag: '$(Build.BuildId)'

  # Agent VM image name
  vmImageName: 'ubuntu-latest'

stages:
- stage: Build
  displayName: Build and push stage
  jobs:  
  - job: Build
    displayName: Build
    pool:
      vmImage: $(vmImageName)
    steps:
    - task: Docker@2
      displayName: Build and push an image to container registry
      inputs:
        command: buildAndPush
        repository: $(imageRepository)
        dockerfile: $(dockerfilePath)
        containerRegistry: $(dockerRegistryServiceConnection)
        tags: |
          $(tag)

- stage: Deploy
  displayName: Deploy
  jobs:  
  - job: Deploy
    displayName: Deploy
    pool:
      vmImage: $(vmImageName)
    steps:
    - task: Kubernetes@1
      displayName: Deploy an image to AKS
      inputs:
        connectionType: 'Azure Resource Manager'
        azureSubscriptionEndpoint: 'XXXXXXX'
        azureResourceGroup: 'AKSCICDRG'
        kubernetesCluster: 'HealthCareAKSCluster'
        command: 'apply'
        arguments: '-f patientservice.yaml'
        secretType: 'dockerRegistry'
        containerRegistryType: 'Azure Container Registry'

图像已成功推送到 ACR，构建步骤运行良好。

即使部署步骤也运行良好，但当我在 AKS 集群中执行“kubectl get pods”时，我得到的 pod 状态为 ImagePullBackOff 或 ErrImagePull。当我执行“kubectl描述pod”时，我收到以下消息:

Failed to pull image "patientservice": rpc error: code = Unknown desc = Error response from daemon: pull access denied for patientservice, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

请帮助我如何部署正确的镜像。

Answer 1

问题出在 Patientservice.yaml 文件中。我忽略了它。以前的图像只有服务名称。我将以下内容添加到 Patientservice.yaml 中的图像中:

image: healthcareakscicdacr.azurecr.io/patientservice:latest

部署工作正常。
