Serverless Kubernetes (ASK) clusters provide the NGINX Ingress controller, which is optimized based on the open source NGINX Ingress controller. This topic describes how to install the NGINX Ingress controller in an ASK cluster.
Procedure
Method 1: Install the NGINX Ingress controller when you create a cluster
When you create an ASK cluster, select Install Ingress Controllers in the Ingress section. For more information, see Create an ASK cluster.

Note To install the NGINX Ingress controller, make sure that the following two conditions
are met:
- Two elastic container instances that have 2 CPU cores and 4 GiB of memory each are used to deploy services.
- A Server Load Balancer (SLB) instance is created. You can set the network type of the SLB instance to Public Network or Internal Network and select the SLB instance specifications based on your business requirements.
