Install Ingress APISIX on ACK

This document explains how to install Ingress APISIX on ali-cloud ACK.

Prerequisites#

  • Create an ACK Service on ali-cloud.
  • Download the kube config for your ACK, follow the introduction.
  • Install Helm.

Install APISIX and apisix-ingress-controller#

As the data plane of apisix-ingress-controller, Apache APISIX can be deployed at the same time using Helm chart.

helm repo add apisix https://charts.apiseven.comhelm repo add bitnami https://charts.bitnami.com/bitnamihelm repo updatekubectl create ns ingress-apisixhelm install apisix apisix/apisix \  --set gateway.type=LoadBalancer \  --set ingress-controller.enabled=true \  --set etcd.persistence.storageClass="alicloud-disk-ssd" \  --set etcd.persistence.size="20Gi" \  --namespace ingress-apisix \  --set ingress-controller.config.apisix.serviceNamespace=ingress-apisixkubectl get service --namespace ingress-apisix

Five Service resources were created.

  • apisix-gateway, which processes the real traffic;
  • apisix-admin, which acts as the control plane to process all the configuration changes.
  • apisix-ingress-controller, which exposes apisix-ingress-controller's metrics.
  • apisix-etcd and apisix-etcd-headless for etcd service and internal communication.

The gateway service type is set to LoadBalancer (See Access services through SLB for more details), so that clients can access Apache APISIX through a 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}'

ACK PV require min_size is 20Gi,cluster with flexVolume component select alicloud-disk-ssd,if with helm values.yml configure startup apisix,more helm etcd configure,configure format sample:

etcd:  persistence:    storageClass: "alicloud-disk-ssd"    size: 20Gi

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.

Specify The Ingress Version#

apisix-ingress-controller will watch apiVersion of networking.k8s.io/v1 by default. If the target kubernetes version is under v1.19, add --set ingress-controller.config.kubernetes.ingressVersion=networking/v1beta1 or --set ingress-controller.config.kubernetes.ingressVersion=extensions/v1beta1 if your kubernetes cluster is under v1.16

Enable SSL#

The ssl config is disabled by default, add --set gateway.tls.enabled=true to enable tls support.

Change default apikey#

It's Recommended to change the default key by add --set ingress-controller.config.apisix.adminKey=ADMIN_KEY_GENERATED_BY_YOURSELF, --set admin.credentials.admin=ADMIN_KEY_GENERATED_BY_YOURSELF, --set admin.credentials.viewer=VIEWER_KEY_GENERATED_BY_YOURSELF, notice that ingress-controller.config.apisix.adminKey and admin.credentials.admin must be the same, and should better not same as admin.credentials.viewer.
