Ingress controller for Managed Service for Kubernetes

Application Load Balancer provides the Application Load Balancer Ingress controller as a tool to create and manage load balancers in Managed Service for Kubernetes clusters.

After installing the controller, you will be able to use it to create an Ingress resource to handle incoming traffic. Based on the Ingress configuration, an L7 load balancer will be deployed automatically with all the requisite Application Load Balancer resources.

Sample configurationSample configuration

Below is an abbreviated sample configuration for an Ingress resource. It will be used to create a load balancer to receive HTTPS traffic and to distribute it to two services based on the URI request path.

Logging settingsLogging settings

To set up logging for an L7 load balancer created using an Application Load Balancer Ingress controller in your Managed Service for Kubernetes cluster, add the ingress.alb.yc.io/group-settings-name annotation with a name for the Ingress group settings and specify the settings in the additional IngressGroupSettings resource. For more information, see Ingress resource annotations.
