Azure App Service Web (Linux or Windows)

This Terraform module creates an Azure Service Plan using our dedicated Terraform module and creates an Azure App Service Web (Linux or Windows) associated with an Application Insights component and activated Diagnostics Logs.

Limitations

Diagnostics logs only works fine for Windows for now.
Untested with App Service slots.
Using a single certificate file on multiple domains with the custom_domains variable is not supported. Use a Key Vault certificate instead.

Contributing

If you want to contribute to this repository, feel free to use our pre-commit git hook configuration which will help you automatically update and format some files for you by enforcing our Terraform code module best-practices.

More details are available in the CONTRIBUTING.md file.

Usage

This module is optimized to work with the Claranet terraform-wrapper tool which set some terraform variables in the environment needed by this module. More details about variables set by the terraform-wrapper available in the documentation.

⚠️ Since modules version v8.0.0, we do not maintain/check anymore the compatibility with Hashicorp Terraform. Instead, we recommend to use OpenTofu.
