What's New in Terraform Azure Provider: Network Ddos Protection Plan, Private Dns A Record

TL;DR

Several new list resources are now available, expanding querying capabilities for services like Redis, MSSQL, and Private DNS.

Java 25 is now supported across both Linux and Windows variants of Web Apps and Function Apps.

Python 3.14 support has been introduced for Linux Web Apps and their associated deployment slots.

Grafana dashboards gained support for major version 12, while the deprecated version 10 was removed.

A bug preventing the API from receiving initial delay settings for startup and readiness probes in Container App Jobs has been resolved.

Editor's Note: We view this release as a routine capability expansion that aligns with recent trends of supporting bleeding-edge runtime versions like Java 25 and Python 3.14. While mostly additive, the removal of Grafana version 10 requires attention from teams managing older observability stacks. A good practice before upgrading is to audit your azurerm_dashboard_grafana configurations to ensure no instances are left on the unsupported version.

What Changed

#### Deprecation

The 10 value is no longer accepted in the grafana_major_version property for the azurerm_dashboard_grafana resource.

#### Behavior

For azurerm_container_app_job, the provider now correctly sets template.container.startup_probe.initial_delay and template.container.readiness_probe.initial_delay in the API request, fixing an issue where these values were previously ignored.

#### Feature

Added support for the 12 value in the grafana_major_version property for azurerm_dashboard_grafana.

Introduced new list resources for infrastructure querying: azurerm_network_ddos_protection_plan, azurerm_private_dns_a_record, azurerm_private_endpoint, azurerm_redis_cache, azurerm_redis_firewall_rule, azurerm_route, azurerm_mssql_elasticpool, and azurerm_mssql_virtual_machine.

Updated the underlying databricks dependency to API version 2026-01-01.

Updated the underlying dataprotection dependency to API version 2025-09-01.

Added 25 as a valid value for the java_version property in azurerm_linux_function_app, azurerm_linux_web_app, azurerm_windows_function_app, and azurerm_windows_web_app.

Enabled 3.14 in the python_version property for azurerm_linux_web_app and azurerm_linux_web_app_slot.

Who's Impacted

If you manage azurerm_dashboard_grafana resources pinned to version 10, you will experience validation failures upon applying this update.

If you previously configured initial_delay for probes in azurerm_container_app_job, you might notice those delays taking effect for the first time during your next deployment.

Action Checklist

☐ Search the codebase for azurerm_dashboard_grafana resources using grafana_major_version = "10".

☐ Update any identified Grafana instances to version 12 (or another supported version).

☐ Review azurerm_container_app_job configurations to verify if startup_probe.initial_delay is set.

☐ Verify readiness_probe.initial_delay settings in container app jobs to ensure the newly applied delays function as intended without breaking deployment pipelines.

☐ Check if existing custom data sources can be replaced by the new azurerm_network_ddos_protection_plan list resource.

☐ Evaluate adopting the azurerm_private_dns_a_record list resource for internal DNS auditing modules.

☐ Assess the new azurerm_private_endpoint list resource to simplify network inventory scripts.

☐ Plan testing for Java 25 upgrades in azurerm_linux_function_app deployments.

☐ Coordinate with development teams to test Java 25 on azurerm_windows_web_app environments.

☐ Validate Python 3.14 compatibility for applications hosted on azurerm_linux_web_app.

☐ Update staging environments using azurerm_linux_web_app_slot to test the new Python 3.14 runtime.

☐ Review Databricks deployments to account for the internal 2026-01-01 API version update.
