Introduction

The custom resource deployment model involves creating an IBM Application Gateway custom resource. The IBM Application Gateway operator will handle the creation and lifecycle management of the IBM Application Gateway instance.

Custom Resource Model

The example described in this document shows how custom resources can be used to protect an application using IBM Application Gateway.

Note: It is assumed that the IBM Application Gateway operator has already been installed into the environment and is available.

Steps

The following steps will:

  • Create an instance of the IBM Application Gateway using a custom resource
  • Access a protected application via the IBM Application Gateway
    • The page will show the identity and other headers that have been added to the request by the IBM Application Gateway

This example does not include authentication. This example illustrates the deployment process for using IBM Application Gateway as a proxy to a protected application.

  1. Paste the following into a file named iag_service_account.yaml.
apiVersion: v1
kind: ServiceAccount
metadata:
  name: ibm-application-gateway
  1. Create the service account.
kubectl create -f iag_service_account.yaml
  1. Paste the following into a file named co.yaml.
apiVersion: ibm.com/v1
kind: IBMApplicationGateway
metadata:
  name: iag-instance
spec:
  replicas: 1
  deployment:
    serviceAccountName: ibm-application-gateway
