# Azure DevOps Pipeline - Deploy to Azure App Service
# Use this pipeline after images have been built and pushed to ACR
# 
# To use this pipeline:
# 1. Make sure images exist in ACR (run azure-pipelines.yml first)
# 2. Update variables below with your Azure resource names
# 3. Create Azure service connection for App Service deployment
# 4. Create 'production' environment in Azure DevOps
# 5. Configure this pipeline in Azure DevOps

trigger:
  branches:
    include:
      - main
  tags:
    include:
      - 'v*'

pool:
  vmImage: 'ubuntu-latest'

variables:
  # Azure Container Registry configuratie
  acrName: 'zdlas'  # Pas aan naar jouw ACR naam
