Publish to Azure Service Bus from PowerShell

powershell-svc-bus

Overview

The Azure Portal include a service bus explorer tool. This can be used to publish a message to a queue or a topic. However, this is a little limmited. While testing I found it frustrating that I needed to paste in the message body each time, along with a couple of custom properties.

Azure REST API

When automating Azure, my first port of call is Azure CLI. However it seems this does not yet support publishing of messages to service bus. So, I turned to the Azure REST API.

Two Steps

There are two steps required:

1. obtain the auth header for the rest post
2. post the request

I have separated these into individual PowerShell scripts, which can be found at this github repo. The entry point is "post-msg.ps1". You can see that this requires a sas token to be set. This can be found by navigating the Azure Portal to Service Bus Namespace/Shared access policies/RootManageSharedAccessKey (or create a new one)/Primary Key

The top level script calls the "generate-sas-token.ps1" script in order to generate the sas token that is used in the header of the post request to the azure api.
