The Application Gateway Ingress Controller allows the Azure Application Gateway to be used as the ingress for an Azure Kubernetes Service aka AKS cluster. As shown in the figure below, the ingress controller runs as a pod within the AKS cluster. It consumes Kubernetes Ingress Resources and converts them to an Azure Application Gateway configuration which allows the gateway to load-balance traffic to Kubernetes pods.
This module helps in deploying the necessary resources for the greenfield deployment of necessary resources for AKS cluster with Application Gateway as ingress controller.
Setup
- Greenfield Deployment: If you are starting from scratch, refer to these installation instructions which outlines steps to deploy an AKS cluster with Application Gateway and install application gateway ingress controller on the AKS cluster.
Usage
Refer to the tutorials to understand how you can expose an AKS service over HTTP or HTTPS, to the internet, using an Azure Application Gateway.
