Install Ingress APISIX on Google Cloud GKE

This document explains how to install Ingress APISIX on Google Cloud GKE.

Prerequisites#

  • Create an Kubernetes Service on GKE.
  • Install Google Cloud SDK and get the credentials or you can just use the Cloud Shell.
  • Install Helm.
  • Clone Apache APISIX Charts.
  • Make sure your target namespace exists, kubectl operations thorough this document will be executed in namespace ingress-apisix.

Install APISIX#

Apache APISIX as the proxy plane of apisix-ingress-controller, should be deployed in advance.

cd /path/to/apisix-helm-chart
helm repo add bitnami https://charts.bitnami.com/bitnami
helm dependency update ./charts/apisix
helm install apisix ./charts/apisix \
  --set gateway.type=LoadBalancer \
  --set allow.ipList="{0.0.0.0/0}" \
  --namespace ingress-apisix
kubectl get service --namespace ingress-apisix

Two Service resources were created, one is apisix-gateway, which processes the real traffic; another is apisix-admin, which acts as the control plane to process all the configuration changes.

The gateway service type is set to LoadBalancer, so that clients can access Apache APISIX through the GKE Load Balancer . You can find the load balancer IP by running:

kubectl get service apisix-gateway --namespace ingress-apisix -o jsonpath='{.status.loadBalancer.ingress[].ip}'

Another thing should be concerned that the allow.ipList field should be customized according to the Pod CIRD configuration of GKE, so that the apisix-ingress-controller instances can access the APISIX instances (resources pushing).

Install apisix-ingress-controller#

You can also install apisix-ingress-controller by Helm Charts, it's recommended to install it in the same namespace with Apache APISIX.

cd /path/to/apisix-helm-chart
# install apisix-ingress-controller
helm install apisix-ingress-controller ./charts/apisix-ingress-controller \
  --set image.tag=dev \
  --set config.apisix.baseURL=http://apisix-admin:9180/apisix/admin \
  --set config.apisix.adminKey=edd1c9f034335f136f87ad84b625c8f1 \
  --namespace ingress-apisix

Change the image.tag to the apisix-ingress-controller version that you desire. You have to wait for while until the corresponding pods are running.

Now try to create some resources to verify the running status. As a minimalist example, see proxy-the-httpbin-service to learn how to apply resources to drive the apisix-ingress-controller.
