Azure Devops kubectl task deployed image is with status ErrImagePull/ImagePullBackOff - azure

Question

I have created a deployment pipeline using Azure Devops through which I am building and pushing an image to Azure Container Registry.
In the next step I am deploying from ACR to an AKS cluster which I have created and attached to ACR using the following command:
az aks create -n HealthCareAKSCluster -g AKSCICDRG --generate-ssh-keys --attach-acr HealthCareAKSCICDACR
Following is my yaml code:
# 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'
The image is getting pushed to ACR successfully and Build step is running fine.
Even deploy step is running fine but when I do 'kubectl get pods' in my AKS cluster I am getting the pod status as ImagePullBackOff or ErrImagePull.
When I did 'kubectl describe pod' I am getting the following message:
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
Please help as to how can I deploy a proper image.

Answer 1

The issue was in patientservice.yaml file. I overlooked it. Previously image had only the name of the service.I added the following to the image in patientservice.yaml:
image: healthcareakscicdacr.azurecr.io/patientservice:latest
The deployment worked fine.
