Configuration Examples

APISIX Ingress Controller supports both Ingress resources and Gateway API for traffic management in Kubernetes. While both are supported, the Gateway API provides greater flexibility and extensibility. New users are encouraged to adopt Gateway API for future deployments.

In addition to these standard Kubernetes APIs, the APISIX Ingress Controller also supports a set of CRDs (Custom Resource Definitions) designed specifically for APISIX-native functionality.

This document provides examples of common configurations covering how and when to use these resources. You should adjust custom values such as namespaces, route URIs, and credentials to match your environment.

note

Currently there are no differences between APISIX Ingress Controller and API7 Ingress Controller.

Configure CP Endpoint and Admin Key

spec:
  provider:
    type: ControlPlane
    controlPlane:
      endpoints:
      - http://127.0.0.1:9180
      auth:
        type: AdminKey
        adminKey:
          value: replace-with-your-admin-key

Configure Gateway Access Information

These configurations allow Ingress Controller users to access the gateway.

Gateway API

To configure the statusAddress:

apiVersion: apisix.apache.org/v1alpha1
kind: GatewayProxy
metadata:
  name: apisix-config
spec:
  statusAddress:
    - 10.24.87.13

Ingress

If you are using Ingress resources, you can configure either statusAddress or publishService.

To configure the statusAddress:

apiVersion: apisix.apache.org/v1alpha1
kind: GatewayProxy
metadata:
  name: apisix-config
spec:
  statusAddress:
    - 10.24.87.13

To configure the publishService:

apiVersion: apisix.apache.org/v1alpha1
kind: GatewayProxy
metadata:
  name: apisix-config
spec:
  publishService: apisix-ee-3-gateway-gateway

When using publishService, make sure your gateway Service is of LoadBalancer type so that the address can be populated. The controller will use the endpoint of this Service to update the status information of the Ingress resource. The format can be either namespace/svc-name or simply svc-name if the default namespace is correctly set.

APISIX CRD

Not supported.
