IBM Application Gateway Operator Example

The IBM Application Gateway can be deployed in Kubernetes as an instance of the custom object type IBMApplicationGateway. This allows the maintenance of the container to be handled by the custom Kubernetes IBM Application Gateway operator.

Operator Deployment Model

The operator deployment of IBM Application Gateway is suitable when:

  • The application to protect is an application that is running outside of the Kubernetes infrastructure
  • The IBM Application Gateway configuration needs to be split across multiple sources
  • There are multiple instances of the IBM Application Gateway required. (The operator will manage all instances with minimal assistance from the Kubernetes administrator)

Example

The following steps will:

  • Setup the IBM Application Gateway operator
  • Create an instance of the IBM Application Gateway
  • Access the 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

Steps 1 - 11 are required to setup the IBM Application Gateway operator. To deploy further applications other than the one listed in the subsequent steps, the operator setup does NOT need to be performed again.

Note: This example does not include authentication. This example illustrates the deployment process for using IBM Application Gateway as a proxy to a protected application. For details on adding authentication, refer to Configuring as an OIDC Relying Party for IBM Security Verify or Configuring as an OIDC Relying Party for IBM Security Verify Access.

Note: This example uses Minikube with a docker driver

  1. Start Minikube.
minikube start --driver docker
  1. Set context.
kubectl config use-context minikube
eval $(minikube docker-env)
  1. Paste the following into a file named operator_service_account.yaml.
apiVersion: v1
kind: ServiceAccount
metadata:
  name: ibm-application-gateway-operator
  1. Create the operator service account.
kubectl apply -f operator_service_account.yaml
