Deploy Azure Service Bus and Azure Function using Terraform and Azure devOps
Overview:
The Article give an overview of how to use terraform with Azure Devops to deploy
Azure Infrastructure and Azure Function App.
Tools used:
Terraform, Azure DevOps, Azure Service Bus, Azure Web App
Solution Diagram:
Create Terraform file to create Azure Service Bus and Azure Function App
Create Azure Function project using Visual studio.
Create Azure DevOps CI CD Pipeline to deploy terraform and Azure Function
Create Azure Function Project
Use Service Bus Topic Trigger
Create Terraform code to create Azure Service Bus and Azure Function
