Project files not available in deploy job azure dev ops pipelines - azure

Question

The files in the related repo are available when running the Build stage of the Azure Dev Ops pipeline, but not when running the deploy stage. Any ideas as to why this would be the case?
Here is a simplified version of the yaml file:
# Deploy to Azure Kubernetes Service
# Build and push image to Azure Container Registry; Deploy to Azure Kubernetes Service
# https://learn.microsoft.com/azure/devops/pipelines/languages/docker
trigger:
- master
resources:
- repo: self
variables:
# Agent VM image name
vmImageName: 'ubuntu-latest'
# Name of the new namespace being created to deploy the PR changes.
k8sNamespaceForPR: 'review-app-$(System.PullRequest.PullRequestId)'
stages:
- stage: Build
displayName: Build stage
jobs:
- job: Build
displayName: Build
pool:
vmImage: $(vmImageName)
steps:
- task: Bash#3
inputs:
targetType: 'inline'
script: |
pwd
ls -la
- stage: Deploy
displayName: Deploy stage
dependsOn: Build
jobs:
- deployment: Deploy
condition: and(succeeded(), not(startsWith(variables['Build.SourceBranch'], 'refs/pull/')))
displayName: Deploy
pool:
vmImage: $(vmImageName)
environment: 'test.development'
strategy:
runOnce:
deploy:
steps:
- task: Bash#3
inputs:
targetType: 'inline'
script: |
pwd
ls -la
Additional notes:
If the deploy stage is run first (the build stage is removed) the working directory is also empty.

Answer 1

The job in your Deploy stage is a deployment job rather than a standard job, deployment jobs don't automatically checkout the repo that the pipeline is based on but they do have access to any published pipeline artifacts.
You can either publish a pipeline artifact in the Build stage or add a task to your Deploy stage to explicitly checkout the repo.
To publish a pipeline artifact add the Publish Pipeline Artifact as task in your Build stage. In your Deploy stage you can then reference files in that artifact with the path $(Pipeline.Workspace)/<artifactName>/<rest-of-path>
To checkout out the whole repo add this to your Deploy stage:
steps:
- checkout: self
path: 'myrepo/'
Then reference the files in the repo using $(System.DefaultWorkingDirectory)\<rest-of-path>
