Application Gateway

This module will create an application gateway.

You can optionally configure the following:

  • Web Application Firewall (WAF)
  • Application Gateway Firewall Policy
  • Key vault integration with a managed identity for certificate retrieval
  • Diagnostic logs and resource lock

Usage

Example 1 - Application Gateway with diagnostic logs and resource lock

param deploymentName string = 'appgw${utcNow()}'

module appGateway 'applicationgateway.bicep' = {
  name: deploymentName
  params: {
    applicationGatewayName: 'MyApplicationGateway'
    sku: 'Standard_v2'
    tier: 'Standard_v2'
    zoneRedundant: true
    publicIpAddressName: 'MyPublicIpAddress'
    vNetResourceGroup: 'MyVnetResourceGroup'
    vNetName: 'MyVnetName'
    subnetName: 'MySubnetName'
    frontEndPorts: [
      {
        name: 'port_80'
        port: 80
      }
    ]
    httpListeners: [
      {
        name: 'MyHttpListener'
        protocol: 'Http'        
        frontEndPort: 'port_80'
      }
    ]
    backendAddressPools: [
      {
        name: 'MyBackendPool'
        backendAddresses: [
          {
            ipAddress: '10.1.2.3'
          }
        ]
      }
    ]
    backendHttpSettings: [
      {
        name: 'MyBackendHttpSetting'
        port: 80
        protocol: 'Http'
        cookieBasedAffinity: 'Enabled'
        affinityCookieName: 'MyCookieAffinityName'
        requestTimeout: 300
        connectionDraining: {
          drainTimeoutInSec: 60
          enabled: true
        }
      }
    ]
    rules: [
      {
        name: 'MyRuleName'
        ruleType: 'Basic'
        listener: 'MyHttpListener'
        backendPool: 'MyBackendPool'
        backendHttpSettings: 'MyBackendHttpSetting'
      }
    ]
    enableDeleteLock: true
    enableDiagnostics: true
    logAnalyticsWorkspaceId: 'MyLogAnalyticsWorkspaceResourceId'
