Installation

Requirements

• Terraform >= 1.3.0
• Azure Provider (azurerm) >= 4.31.0
• Azure subscription with appropriate permissions
• Log Analytics Workspace for Container App Environment

The integration is designed to be run once per Azure subscription and the Upwind platform uses the subscription as a way to group together Azure Container App resources.

Installation

To deploy Upwind components on Azure Container Apps the recommended approach is to utilize the Terraform module that we maintain. The module deploys the Upwind Cluster Manager with the tracer embedded, along with supporting infrastructure.

1. Log in to the Upwind Management Console .
2. Select the + (plus) symbol at the top of the screen and select Connect Azure Container App.
3. Enter the subscription ID where your Container Apps are deployed.
4. Under Sensor credentials, click Generate to create a new client ID and client secret. Provide a name and click Generate. If you already have Sensor credentials, you may skip this step and select existing credentials from the list.

provider "azurerm" {
  features {}
  subscription_id = "{SUBSCRIPTION_ID}"
}

module "upwind_integration_azure_container_app" {
  source = "https://get.upwind.io/terraform/modules/azure-onboarding/azure-container-app-latest.tar.gz"

  resource_group_name            = "{RESOURCE_GROUP_NAME}"
  container_app_environment_name = "{CONTAINER_APP_ENVIRONMENT_NAME}"

  upwind_client_id     = "{UPWIND_CLIENT_ID}"
  upwind_client_secret = "{UPWIND_CLIENT_SECRET}"
}

Installation with VNet Integration (Optional)

To optionally deploy the cluster manager into an existing VNet, add the infrastructure_subnet_id parameter with your subnet ID. The subnet must have a minimum /23 CIDR range and be delegated to Microsoft.App/environments.

For App Service workloads to send traces to the cluster manager, you may also need:

• internal_load_balancer_enabled - Removes the public endpoint so the cluster manager is only accessible within the VNet
• create_private_dns_zone - Creates a private DNS zone linked to the VNet so App Services can resolve the cluster manager's internal hostname

note

Container App Environment VNet integration must be configured at creation time. An existing environment cannot be moved into a VNet.

What Gets Deployed

The module creates the following resources:

1. Resource Group (optional): Container for all Upwind resources
2. Key Vault: Stores Upwind credentials securely
3. Container App Environment: Managed environment with a dedicated workload profile (D4)
4. Cluster Manager Container App:
   • Runs the Upwind cluster agent with the tracer embedded
   • Configured with 4 CPU and 8GB memory
   • Exposes an HTTP2 ingress endpoint for receiving traces from application containers
   • Auto-scales between 1-3 replicas based on demand

The cluster manager is deployed with the Upwind tracer embedded in the container, allowing it to trace its own operations while also serving as the collection endpoint for traces from your application containers.
