Due to Terraform's cross-cloud compatibility, automation, and efficient execution, among many other advantages, more and more customers use it to deploy integration solutions based on Azure Logic App standard.

However, despite the extensive contributions from the community and individual contributors providing Terraform templates and supporting VNET integration solutions for Logic App standards, there are still very few terraform templates covering the "Application routing" and "Configuration routing" settings:

This article shared a mature plan to deploy logic app standard then set the mentioned routing features automatically. It's based on Terraform template and Azure DevOps Pipeline.

About Terraform Template:

Please kindly find the the template in directory Terraform/LAStandard.tf, it includes the terraform definitions for logic app standard, the backend storage account, application insights, virtual network and VNET integration settings.

About VNET Routing Configuration

Because there is no terraform examples available for VNET routing, we add VNET Settings by invoking "Patch" request to ARM RESTful API endpoint for interacting with logic app standard site:

https://management.azure.com/subscriptions/<Your subscription id>/resourceGroups/$(deployRG)/providers/Microsoft.Web/sites/$(deployLA)?api-version=2022-03-01

We figured out the required request body in network trace as the following format:

{
"properties": {
"vnetContentShareEnabled": false,
"vnetImagePullEnabled": true,
"vnetRouteAllEnabled": false,
"vnetBackupRestoreEnabled": false
}
}

Please find the YAML file in TerraformPipeline/logicappstandard-terraform.yml. Within the Yaml file , the "AzureCLI@2" task is used to send the request by Azure CLI command.
