    Nginx Ingress Introduction

    Nginx can be used as a reverse proxy, load balancer, and for HTTP caching.

    Nginx-ingress is an Ingress controller for Kubernetes that uses NGINX as a reverse proxy and load balancer. You can deploy and use Nginx-ingress addon in the cluster. TKE provides productized capabilities to help you install and use Nginx-ingress in the cluster.

    Nginx-ingress Concepts

    • Nginx-ingress Addon: you can use Nginx-ingress in TKE through Nginx-ingress addon. Install and deploy Nginx-ingress addon with one click on the Addon Management page.
    • Nginx-ingress Instance: you can deploy multiple Nginx-ingress instances in a cluster (for example, one for the public network and one for the private network). Each instance corresponds to a CRD resource in Kubernetes. When an Nginx-ingress instance is created, Nginx-ingress-controller, service, configmap and other Kubernetes resources will be automatically created in the cluster.
    • Nginx-ingress-controller: the actual Nginx load. The controller will watch the kubernetes ingress object and update the changes in the cluster. The forwarding configuration of Nginx load is the nginx.conf file.
