Kafka in Azure Event Hub

This module creates and manages a Kafka-compatible serverless event streaming platform. Key features:

Event Hub namespace management with authorization rule
optional network rules configuration
Kafka topics (Event Hubs) management

NOTE: This module is meant to be used with an already created resource group

The module follows Azure naming conventions. Name variables passed to the module are only suffixes used in the full resource names that are defined by Azure standards

Abbreviations are used for resource names in most cases, based on these Azure recommendations

Define update strategy

Corewide DevOps team strictly follows Semantic Versioning Specification to provide our clients with products that have predictable upgrades between versions. We recommend pinning patch versions of our modules using pessimistic constraint operator (~>) to prevent breaking changes during upgrades.

To get new features during the upgrades (without breaking compatibility), use ~> 1.0 and run terraform init -upgrade

For the safest setup, use strict pinning with version = "1.0.0"

Create an Event Hub namespace with Event Hubs (Kafka topics), specified tier, access allowed from the specific subnet, and tags:

NOTE: subnet must have the Microsoft.EventHub service endpoint enabled

 hclresource "azurerm_resource_group" "foo" {
  name     = "foo"
  location = "eastus"
}

module "kafka" {
  source  = "solutions.corewide.com/azure/tf-azure-eventhub-kafka/azurerm"
  version = "~> 1.0"

  name_suffix         = "bar"
  region              = azurerm_resource_group.foo.location
  resource_group_name = azurerm_resource_group.foo.name
  tier                = "Premium"

  topics = [
    { name = "queue" },
    { name = "messages" },
  ]

  network_rules = {
    enabled               = true
    public_access_enabled = false
    allowed_subnet_ids    = ["/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/mygroup1/providers/Microsoft.Network/virtualNetworks/myvnet1/subnets/mysubnet1"]
  }

  tags = {
    Layer = "Data"
  }
}

Minimal setup with required parameters only:

 hclresource "azurerm_resource_group" "foo" {
  name     = "foo"
  location = "eastus"
}

module "kafka" {
  source  = "solutions.corewide.com/azure/tf-azure-eventhub-kafka/azurerm"
  version = "~> 1.0"

  name_suffix         = "bar"
  region              = azurerm_resource_group.foo.location
  resource_group_name = azurerm_resource_group.foo.name
}
