How to deploy two zipped Functions to the same Azure Function App? - azure

Question

I trying to deploy two zipped Functions to the same Azure Function App called http-trigger-api-test and the result is that the first one gets deployed but then it is replaced by the second function.
I have the tasks in the following yaml file:
- stage: Build
displayName: Build stage for Azure Function
jobs:
- job: Build
steps:
- task: ArchiveFiles#2
displayName: 'Archive HttpTriggerApi Azure Function'
inputs:
rootFolderOrFile: 'azure/azure_functions/HttpTriggerApi/function_code'
includeRootFolder: false
archiveType: zip
archiveFile: $(Build.ArtifactStagingDirectory)/$(Build.BuildId).zip
replaceExistingArchive: true
- task: ArchiveFiles#2
displayName: 'Archive HttpTriggerApiWeb Azure Function'
inputs:
rootFolderOrFile: 'azure/azure_functions/HttpTriggerApi/function_code_web'
includeRootFolder: false
archiveType: zip
archiveFile: $(Build.ArtifactStagingDirectory)/$(Build.BuildId)2.zip
replaceExistingArchive: true
- upload: $(Build.ArtifactStagingDirectory)/$(Build.BuildId).zip
displayName: 'Upload Azure Function Full Stack'
artifact: full_stack_deploy
- upload: $(Build.ArtifactStagingDirectory)/$(Build.BuildId)2.zip
displayName: 'Upload Azure Function Web Stack'
artifact: web_deploy
- stage: TEST
displayName: Deploy stage Test
variables:
- group: optimizelyeventconnector-test-group
jobs:
- deployment: Deploy
displayName: Deploy
environment: optimizelyeventconnector-test
pool:
vmImage: $(vmImageName)

steps:
- task: AzureCLI#1
displayName: 'Deploy Azure Function Full Stack'
inputs:
azureSubscription: 'test-group-SPN'
scriptType: 'ps'
scriptLocation: 'inlineScript'
inlineScript: |
az functionapp deployment source config-zip -g test-group -n http-trigger-api-test --src $(Pipeline.Workspace)/full_stack_deploy/$(Build.BuildId).zip
- task: AzureCLI#1
displayName: 'Deploy Azure Function Web Stack'
inputs:
azureSubscription: 'test-group-SPN'
scriptType: 'ps'
scriptLocation: 'inlineScript'
inlineScript: |
az functionapp deployment source config-zip -g test-group -n http-trigger-api-test --src $(Pipeline.Workspace)/web_deploy/$(Build.BuildId)2.zip
I have read some questions where it is suggested not to pack several functions into one function app unless they are related. In my case, both functions are related.
Any suggestion, comment or improvement to this questions is welcome.

After some research I found the solution.
I had to structure my function app in the following way:
- main_function_app
- functions
- Full_Stack
- configAPI.json
- configAPITest.json
- function.json
- index.js
- Web
- configAPI.json
- configAPITest.json
- function.json
- index.js
- host.json
- local.settings.json
- package-lock.json
- package.json
- proxies.json
- utils.js
When deploying to azure, you need to install node, dependencies, zip the files and publish them.
- stage: Build
displayName: Build stage for Azure Function
jobs:
- job: Build
displayName: Build
pool:
vmImage: $(vmImageName)
steps:
- task: NodeTool#0
inputs:
versionSpec: '14.x'
displayName: 'Install Node.js'
- task: Bash#3
inputs:
targetType: 'inline'
script: 'npm install --prefix azure/azure_functions/HttpTriggerApi/main_function_app/functions'
- task: ArchiveFiles#2
displayName: 'Build Azure Functions and Dependencies'
inputs:
rootFolderOrFile: 'azure/azure_functions/HttpTriggerApi/main_function_app/functions'
includeRootFolder: false
archiveType: zip
archiveFile: $(Build.ArtifactStagingDirectory)/$(Build.BuildId).zip
replaceExistingArchive: true
- upload: $(Build.ArtifactStagingDirectory)/$(Build.BuildId).zip
displayName: 'Publish Azure Functions Artifact'
artifact: functions
