Simple HelloWorld ASP.NET Core 8.0 MVC application deployed to Azure Container Apps using Terraform and Azure DevOps.

This project demonstrates a complete CI/CD pipeline for deploying a containerized ASP.NET Core application to Azure Container Apps using Terraform infrastructure as code and Azure DevOps pipelines with automated integration testing.

1. .NET 8.0 SDK
2. Docker
3. Azure subscription with Container Apps resources
4. Azure Container Registry
5. Terraform ~> 1.0
6. Chromium browser (for Playwright integration tests)

The application is deployed via Azure DevOps pipeline (Infrastructure/Pipelines/helloworld-dev-pipeline.yml):

1. Build - Builds and pushes Docker image to Azure Container Registry (tagged with Build ID)
2. TerraformPlan - Runs terraform plan with unique state file per build
3. Deploy - Runs terraform apply to create/update Azure Container App with ingress configuration
4. Test - Runs Playwright integration tests against the deployed Container App URL
5. Teardown - Optionally runs terraform destroy to remove resources (controlled by pipeline parameter, default: true)

The pipeline requires the following variables:

• ContainerRegistrySC - Service connection for Azure Container Registry
• AzureResourceManagerSC - Azure subscription service connection with Terraform backend access
• ContainerRegistryLoginServer - ACR URL (e.g., ncontracts.azurecr.io)
• ManagedIdentityName - User-assigned managed identity for ACR authentication
• EnvironmentName - Environment name for resource naming (e.g., poc01, dev)

Build the Docker image locally:

cd HelloWorld
docker build -t example/helloworld -f Dockerfile . --no-cache

Run integration tests:

# Set the URL to test against
$env:HomePageUrl = "https://your-container-app-url.azurecontainerapps.io"

# Build and run tests
dotnet build HelloWorld.IntegrationTests/HelloWorld.IntegrationTests.csproj --configuration Debug
pwsh HelloWorld.IntegrationTests/bin/Debug/net8.0/playwright.ps1 install chromium
dotnet test HelloWorld.IntegrationTests/HelloWorld.IntegrationTests.csproj --configuration Debug

Run a single test:

dotnet test HelloWorld.IntegrationTests/HelloWorld.IntegrationTests.csproj --filter "FullyQualifiedName~NavigateToWebsiteRoot"

The Terraform configuration in Infrastructure/Terraform/ provides a simple, developer-friendly infrastructure setup:

• main.tf - Container App resource with data sources for existing infrastructure
• variables.tf - Well-documented input variables with sensible defaults
• providers.tf - Azure provider and remote state backend configuration
• outputs.tf - Exposes Container App URL and metadata for pipeline consumption

cd Infrastructure/Terraform
terraform init
terraform plan
terraform apply
terraform output container_app_url

See Infrastructure/Terraform/README.md for detailed instructions.
