Functions are not listed under function app in Azure Portal

Question

Hello!

I am experiencing an issue trying to deploy a dotnet Azure function using Azure DevOps pipelines. The pipeline is running successfully, the runtime version is detected, but there is no function listed under 'Overview > Functions' in the portal. When I publish the same Function App using a publish profile in Visual Studio however, everything is working fine. When I use 'Download app content' to compare the 2 methods, the function code is there and -seems- to be identical.

I am using the following .yml template:

trigger:
  - master

stages:
  - stage: LintIaC
    jobs:
      - job: LintIaC
        displayName: Lint IaC
        steps:
          - script: |
              az bicep build --file iac/main.bicep
            name: LintIaC
            displayName: Run Bicep linter

  - stage: ValidateIaC
    jobs:
      - job: ValidateBicepCode
        displayName: Validate Bicep code
        steps:
          - task: AzureResourceManagerTemplateDeployment@3

              templateLocation: "Linked artifact"
              csmFile: "./iac/main.bicep"
              deploymentName: $(Build.BuildNumber)

        steps:

            inputs:
              buildType: "current"
              artifactName: "drop"
              downloadPath: "$(System.ArtifactsDirectory)"
          - task: AzureFunctionApp@2
            inputs:
              azureSubscription: "Authenticators"
              appType: functionApp
              appName: "func-silverfintokenmanager-live"
              package: "$(System.ArtifactsDirectory)/drop/build$(Build.BuildId).zip"

What am I missing?

Best regards,

Emiel Van Belle, Glad that you are able to resolve the issue by updating your yaml.

Follow below steps to modify the name of .zip:

1. Specify the name of the .zip file using the --output argument in Publish step. You might also need to use a custom name for the .zip archive.
2. After creating the .zip, add its reference with the custom name in the AzureFunctionApp@2 deployment task.

Modify the DotNetCoreCLI@2 task:

- task: DotNetCoreCLI@2
  inputs:
    command: publish
    arguments: "--configuration Release --output $(Build.ArtifactStagingDirectory)/SilverfinTokenManager_custom.zip"
    projects: "**/*.csproj"
    publishWebProjects: false

And then use this custom name in AzureFunctionApp@2 task:

- task: AzureFunctionApp@2
  inputs:
    azureSubscription: "Authenticators"
    appType: functionApp
    appName: "func-silverfintokenmanager-live"
    package: "$(System.ArtifactsDirectory)/drop/SilverfinTokenManager_custom.zip"
