Creating or updating Application Load Balancer resources using Managed Service for Kubernetes configuration

To manage Application Load Balancer resources using an ingress controller and Yandex Managed Service for Kubernetes Gateway API, create YAML configuration files describing Kubernetes resources, e.g., Ingress, HttpBackendGroup, Gateway, HTTPRoute, etc.

Getting startedGetting started

1. Install kubectl and configure it to work with the new cluster.

2. Install the ingress controller or Gateway API.
3. Create a resource. For configurations of available resources, see Application Load Balancer tool reference for Managed Service for Kubernetes.

Applying a configurationApplying a configuration

To apply a configuration:

1. Navigate to the folder with configuration files.

2. Run the following command:

   kubectl apply -f .
   

   Applying a configuration may take a few minutes.

3. After defining a new Ingress resource for your ingress controller to implement, make sure it was successfully created and got a public IP address:

   kubectl get ingress <Ingress_resource_name>
   

   Result:

   NAME            CLASS   HOSTS          ADDRESS       PORTS   AGE
   <Ingress_name>  <none>  <domain_name>  <IP_address>  80,443  15h
   

   The IP address should appear in the ADDRESS column. Otherwise, the load balancer was not created or was created with an error. Check the logs for the yc-alb-ingress-controller-* pod. (Do not confuse it with the yc-alb-ingress-controller-hc-* pod.)
