This article introduces the relevant knowledge of "how to deploy Apache apisix-ingress-cotroller in ACK". Many people will encounter such a dilemma in the operation of actual cases, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Background

Ingress is a noteworthy module in Kubernetes. As an entrance to external access to Kubernetes cluster services, there are a variety of Ingress controller implementations on the market. Apache/apisix-ingress-controller launched by the domestic real-time and high-performance API gateway Apache APISIX is one of them, which provides services as a more powerful ingress. The author is going to deploy tests on the Aliyun ACK cluster.

Topic description

This article mainly introduces the deployment of apisix-ingress-controller in Aliyun ACK and tests a simple scenario using httpbin.

Deployment Topology

Network topology

Dependency item

ACK cluster of Aliyun; recommended minimum configuration: 3 master nodes: CPU 2 core memory 4G2 worker nodes: CPU 4 core memory 8G

Installation steps

Apisix 2.1 release

Install apisix 2.1 release through helm

$kubectl create ns apisix $git clone https://github.com/apache/apisix-helm-chart.git $cd. / apisix-helm-chart $helm repo add bitnami https://charts.bitnami.com/bitnami $helm dependency update. / chart/apisix $helm install apisix. / chart/apisix\-- set gateway.type=LoadBalancer\-- set allow.ipList= "{0.0.0.0ame0}"\-- namespace apisix

Tips: PVC is specified when etcd is installed. When PVC is deployed in Aliyun, PV needs to be specified as cloud disk. Add: volume.beta.kubernetes.io/storage-class: alicloud-disk-ssd to the annotations of PVC. (for the relationship between PVC and PV, please refer to here.)

Apisix-ingress-controller

Install apisix-ingress-controller through helm

$git clone https://github.com/apache/apisix-ingress-controller.git $cd. / apisix-ingress-controller $helm install ingress-apisix-base-n apisix. / charts/base $helm install ingress-apisix. / charts/ingress-apisix\-set ingressController.image.tag=dev\-- set ingressController.config.apisix.baseURL= http://apisix-admin:9180/apisix/admin\-- set ingressController.config.apisix.adminKey=edd1c9f034335f136f87ad84b625c8f1\-- namespace apisix

test

Check whether the cluster is deployed successfully

Configure a simple route for testing

ApiVersion: apisix.apache.org/v1 kind: ApisixRoute metadata: name: httpbin-route namespace: apisix spec: rules:-host: httpbin.apisix.com http: paths:-backend: serviceName: httpbin servicePort: 80 path: / hello*

Looking at the results through apisix admin api, it is found that the route has been configured correctly.
