Azure Functions Deployment

Deployment workflows for Azure Functions using AZD.

Prerequisites

• Azure Functions project prepared with azd template
• azure.yaml exists and validated
• .azure/deployment-plan.md status = Validated
• Azure Functions Core Tools (optional, for local debugging or when using func commands outside azd workflows)

AZD Deployment

Full Deployment (Infrastructure + Code)

# Deploy everything
azd up --no-prompt

Infrastructure Only

# Provision infrastructure without deploying code
azd provision --no-prompt

Application Only

# Deploy code to existing infrastructure
azd deploy --no-prompt

Preview Changes

# Preview changes before deployment
azd provision --preview

Environment Configuration

Set AZD Environment Variables

These are for azd provisioning, not application runtime:

azd env set AZURE_LOCATION eastus2
azd env set VNET_ENABLED false

⚠️ Important: azd env set sets variables for the azd provisioning process, NOT application environment variables.

Verify Deployment

Check Function App Status

# Show deployment details
azd show

Testing HTTP Endpoints

⚠️ Never use curl -I (HEAD) to test Azure Functions endpoints.

Azure Functions [HttpTrigger] with "get" does not automatically handle HEAD requests. HEAD returns 404 from the routing layer even when GET works correctly, causing false-negative results and misdirected debugging.

✅ DO — Use GET with output suppression

# Check status code only (GET, don't follow redirects)
