Configure Flex Gateway as an Ingress Controller in Local Mode

For Kubernetes deployments in Local Mode, Flex Gateway typically acts as an ingress controller that manages external access to your Kubernetes cluster.

By default, Flex Gateways deployed on Kubernetes in Local Mode are configured as ingress controllers and can consume Ingress resources. The ingress controller configuration is defined in the IngressClass resource parameters in the Flex Gateway Helm chart.

In Kubernetes terminology, IngressClass resources configure a gateway as an ingress controller, and Ingress resources configure a routing between the ingress controller and the Kubernetes services it controls. For a detailed explanation of Kubernetes IngressClass resources and Ingress resources, see Kubernetes Ingress.

In the Helm chart, you can edit the IngressClass configuration or disable the ingress controller functionality.

Before You Begin

  1. Download Flex Gateway for Use in a Kubernetes Cluster.

  2. Register and Run Flex Gateway in a Kubernetes Cluster in Local Mode.

Ingress Class Parameters

The Helm chart includes the following default IngressClass parameters and values:

ingressClass.enabled: true
ingressClass.name: "{releaseName}-{namespace}"
ingressClass.setAsDefault: false

Parameter

Description

Possible values

ingressClass.enabled

Enables Flex Gateway as an IngressClass resource

true or false

ingressClass.name

The name of the IngressClass

Any string

ingressClass.setAsDefault

Sets Flex Gateway as the default IngressClass

true or false

Setting ingressClass.setAsDefault: true defines the Flex Gateway instance as the default IngressClass resource for the cluster. The default IngressClass is the default ingress controller for all Ingress resources you create in the cluster.

If there is no default IngressClass, or if the default IngressClass resource shouldn’t be the ingress controller for a specific resource, you must manually define the ingress controller in the Ingress resource.

You can modify the default IngressClass parameters during or after the initial installation of the Helm chart. For more information about how to modify a Helm chart, see Update Pod Settings for a Flex Gateway Deployment Through a Helm Chart

Creating Ingress Resources

After you install a Helm chart into a namespace, you can verify your new IngressClass resource by running the following command:

kubectl get ingressclasses

To create an ingress routing:

  1. Publish an API in Local Mode.

  2. Define the new API as a Kubernetes Service.
    For more information about Kubernetes Service definitions, see Defining a Service.

  3. Create an Ingress resource to define routing rules between the IngressClass Flex Gateway and the new Kubernetes Service.
    For more information about Ingress resources, see Kubernetes Ingress.
