Terraform Template - Azure Event Hubs

Costa Rica

Last updated: 2026-02-17

This template contains Terraform configurations to create an Azure Event Hubs namespace and an Event Hub (optionally with consumer groups).

Note

The Resource Group is created via the AzAPI provider (management plane) to keep creation idempotent (ARM PUT) and align with other templates in this repository.
Event Hubs namespace names are globally unique. Keeping append_random_suffix = true helps avoid collisions.
