Connect a public floating IP address to a load balancer

To give a load balancer in a private subnet inbound and outbound internet access, you can attach a public floating IP address to it. You can also recreate the load balancer in a public subnet.

If you use a load balancer with a Managed Kubernetes cluster, the load balancer is created in the same network as the cluster nodes by default, and a public floating IP address is allocated for it. To create a load balancer without a public IP address or with an IP address from other subnets, use the Configure load balancer in Managed Kubernetes cluster for Ingress or Create and configure load balancer in Managed Kubernetes cluster for Envoy Gateway guide. For the load balancer to work correctly in the cluster, perform all load balancer actions via kubectl.
