What CGPulse checks

A resource passes this rule when hasVnet must equal true. Anything else is reported as a finding with the evaluated property value attached as evidence.

How to fix it

Integrate with a Virtual Network to route traffic privately. In Azure Portal: Container Apps Environment > Networking > configure VNet (set at creation). See: https://learn.microsoft.com/en-us/azure/container-apps/vnet-custom

CLI

az containerapp env show --ids "{id}" --query "properties.vnetConfiguration"

Bicep

resource env 'Microsoft.App/managedEnvironments@2024-03-01' = {{
  name: '{name}'
  location: location
  properties: {{
    vnetConfiguration: {{
      infrastructureSubnetId: subnetId
      internal: true
    }}
    appLogsConfiguration: {{
      destination: 'log-analytics'
      logAnalyticsConfiguration: {{
        customerId: '<workspace-customer-id>'
        sharedKey: '<workspace-shared-key>'
      }}
    }}
  }}
}}

Terraform

resource "azurerm_container_app_environment" "{name}" {
  name                           = "{name}"
  resource_group_name            = "{rg}"
  location                       = var.location
  log_analytics_workspace_id     = var.workspace_id
  infrastructure_subnet_id       = var.subnet_id
