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.
- 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.
- Brownfield Deployment: If you have an existing AKS cluster and Application Gateway, refer to these installation instructions to install application gateway ingress controller on the AKS cluster.
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.
The Kubernetes Ingress specification does not allow all features of Application Gateway to be exposed through the ingress resource. Therefore we have introduced application gateway ingress controller specific annotations to expose application gateway features through an ingress resource. Please refer to the annotations to understand the various annotations supported by the ingress controller, and the corresponding features that can be turned on in the application gateway for a given annotation.
The best way to report an issue is to create a Github Issue for the project. Please include the following information when creating the issue:
- Subscription ID for AKS cluster.
- Subscription ID for Application Gateway.
- AKS cluster name/ARM Resource ID.
- Application Gateway name/ARM Resource ID.
- Ingress resource definition that might causing the problem.
- The Helm configuration used to install the ingress controller.
