<h1 class="topictitle1">NGINX Ingress Controller</h1>
<div id="body1564122277020"><div class="section" id="cce_10_0034__section26181722164712"><h4 class="sectiontitle">Introduction</h4><p id="cce_10_0034__p20263824122714">Kubernetes uses kube-proxy to expose Services and provide load balancing. The implementation is at the transport layer. When it comes to Internet applications, where a bucket-load of information is generated, forwarding needs to be more fine-grained, precisely and flexibly controlled by policies and load balancers to deliver higher performance.</p>
<p id="cce_10_0034__p126332411274">This is where ingresses enter. Ingresses provide application-layer forwarding functions, such as virtual hosts, load balancing, SSL proxy, and HTTP routing, for Services that can be directly accessed outside a cluster.</p>
<p id="cce_10_0034__p1630618342065">Kubernetes has officially released the Nginx-based Ingress controller. CCE Nginx Ingress controller directly uses community templates and images. The NGINX Ingress Controller generates Nginx configuration and stores the configuration using ConfigMap. The configuration will be written to Nginx pods through the Kubernetes API. In this way, the Nginx configuration is modified and updated. For details, see <a href="#cce_10_0034__section971014351338">How the Add-on Works</a>.</p>

If the TLS version is earlier than v1.2, an error will occur during the negotiation process between the client and Nginx Ingress.

The ingress controller assembles ingresses into the Nginx configuration file (<strong id="cce_10_0034__b639012320451">nginx.conf</strong>) and reloads Nginx to make the configuration changes apply. When it detects that the pod in a Service changes, it dynamically changes the upstream server group configuration of Nginx. In this case, the Nginx process does not need to be reloaded. <a href="#cce_10_0034__fig204075132570">Figure 1</a> shows how this add-on works.</p>
