Azure Devops deploy docker image to ACR using deployment job

[Marcee]

I'm trying to deploy a docker image to Azure Container Registry via an Azure Devops pipeline. Now this works fine when I run it with this script:

trigger:
- master
variables:
Container registry service connection established during pipeline creation
dockerRegistryServiceConnection: 'some_id'

imageRepository: 'worker'

containerRegistry: 'microcontainerapptest.azurecr.io'

dockerfilePath: '$(Build.SourcesDirectory)/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)

However, I want to actually use a deployment job so I can run the pipeline in different environments. Therefore I updated the .yml like this:

trigger:
- master
variables:
Container registry service connection established during pipeline creation
dockerRegistryServiceConnection: 'some_id'

imageRepository: 'worker'

containerRegistry: 'microcontainerapptest.azurecr.io'

dockerfilePath: '$(Build.SourcesDirectory)/Dockerfile'

tag: '$(Build.BuildId)'
Agent VM image name
vmImageName: 'ubuntu-latest'
stages:

stage: Build

displayName: Build and push stage

jobs:

deployment:

displayName: Build docker image

environment: $(DEPLOY_ENVIRONMENT)

strategy:

runOnce:

deploy:

steps:

- task: Docker@2

displayName: Build and push an image to container registry

inputs:

command: buildAndPush

repository: $(imageRepository)

dockerfile: $(Build.SourcesDirectory)/Dockerfile

containerRegistry: $(dockerRegistryServiceConnection)

tags: |

$(tag)

Making a deployment job out of this. Now when I run the pipeline like this I get an error

Unhandled: No Dockerfile matching /home/vsts/work/1/s/Dockerfile was found.

So it seems like the dockerfilePath is not valid anymore when I run it as a deployment job. I have searched but don't have a clue as to why this would be the case, does anybody know the answer to this?

You need to explicitly check out your source code, https://docs.microsoft.com/en-us/azure/devops/pipelines/process/deployment-jobs?view=azure-devops :

A deployment job doesn't automatically clone the source repo. You can checkout the source repo within your job with checkout: self. Deployment jobs only support one checkout step.

strategy:
  runOnce:
    deploy:
      steps:
  - checkout: self
  
  - task: Docker@2
    displayName: Build and push an image to container registry
    inputs:
      command: buildAndPush
      repository: $(imageRepository)
      dockerfile: $(Build.SourcesDirectory)/Dockerfile
      containerRegistry: $(dockerRegistryServiceConnection)
      tags: |
        $(tag)
