Use powershell script to customize azure devOps pipeline? - azure

Question

I have an azure function app that is running on Azure. I am now trying to configure the application based on a powershell script. This powershell script is being used to create azure resources (Ex: KeyVault, ApplicationInsights...) that will be then used by the function app. I created the powershell script and my question here is how can I add the powershell script in the yaml file which is responsible to deploy the application. The powershell script is located in the repository under the name functionapp.ps1 . The idea here is to run the powershell script once the build is finished so in the deploy stage. What I did so far is the following:
stages:
- stage: Build
displayName: Build stage
jobs:
- job: Build
displayName: Build
pool:
vmImage: $(vmImageName)
steps:
- task: DotNetCoreCLI#2
displayName: Build
inputs:
command: 'build'
projects: |
$(workingDirectory)/*.csproj
arguments: --output $(System.DefaultWorkingDirectory)/publish_output --configuration Release
- task: ArchiveFiles#2
displayName: 'Archive files'
inputs:
rootFolderOrFile: '$(System.DefaultWorkingDirectory)/publish_output'
includeRootFolder: false
archiveType: zip
archiveFile: $(Build.ArtifactStagingDirectory)/$(Build.BuildId).zip
replaceExistingArchive: true
- publish: $(Build.ArtifactStagingDirectory)/$(Build.BuildId).zip
artifact: drop
- stage: Deploy
displayName: Deploy stage
dependsOn: Build
condition: succeeded()
jobs:
- deployment: Deploy
displayName: Deploy
environment: 'development'
pool:
vmImage: $(vmImageName)
strategy:
runOnce:
deploy:
steps:
- task: CmdLine#2
inputs:
script: |
echo '$(System.DefaultWorkingDirectory)'
dir
- task: PowerShell#2
inputs:
targetType: 'filePath'
filePath: $(System.DefaultWorkingDirectory)/functionapp.ps1
- task: AzureFunctionApp#1
displayName: 'Azure functions app deploy'
inputs:
azureSubscription: '$(azureSubscription)'
appType: functionApp
appName: $(functionAppName)
package: '$(Pipeline.Workspace)/drop/$(Build.BuildId).zip'
When the stages are being run and it arrives to this task I get the following error:
##[error]Invalid file path 'D:\a\1\s\functionapp.ps1'. A path to a .ps1 file is required.
I tried using the command line task to check the default working directory and I got the following result: D:\a\1\s
I still don't know what I am missing here and why I am getting this error. Can someone please give me a concrete solution to this problem ?
I ended up having the same error. Can someone please tell me what is the issue here ?
