Hello @Klinemeier, Kevin (624),

welcome to this moderated Azure community forum.

An eventhub lives inside an eventhub namespace.

Here is a possible CLI example flow after you have logged in:

az login

First we need a resource group:

az group create --name acsResourceGroup --location westeurope

Notice that when you're prompted about a CLI extension for an extension, install the Azure CLI extension on first use. For more information about extensions, see Use extensions with the Azure CLI.

Try creating a standard size Event Hub Namespace, living inside a resourcegroup:

az eventhubs namespace create --name acs-eventprocessor-service-ehns --resource-group acsResourceGroup -l westeurope --sku Standard

This Event Hub namespace is empty so let’s add an Event Hub:

az eventhubs eventhub create --name messages --resource-group acsResourceGroup --namespace-name acs-eventprocessor-service-ehns --partition-count 4

It is wise to use specific consumer groups for consumers so add a consumer group named ‘aci’:

az eventhubs eventhub consumer-group create --consumer-group-name aci --eventhub-name messages --namespace-name acs-eventprocessor-service-ehns --resource-group acsResourceGroup

To get the connection strings, you can list them:

az eventhubs namespace authorization-rule keys list --resource-group acsResourceGroup --namespace-name acs-eventprocessor-service-ehns --name RootManageSharedAccessKey

To get only the primary key, try:

PRIMARYCONNSTRING=$(az eventhubs namespace authorization-rule keys list --resource-group acsResourceGroup --namespace-name acs-eventprocessor-service-ehns --name RootManageShared
AccessKey --query primaryConnectionString --output tsv)

echo $PRIMARYCONNSTRING

This should give you a head start.

Please check this documentation too for more examples.
