Note, full K8s troubleshooting mind map is available at: “K8s Troubleshooting MindMap”
What is This Error?
In K8s, the error “Backend server number has reached the quota limit of this load balancers” typically means that the number of backend servers (pods) being managed by a load balancer has reached the maximum limit that the load balancer can handle.
A load balancer is responsible for distributing incoming network traffic across multiple backend servers (pods) to ensure that no single server is overwhelmed with too much traffic. This helps maintain high availability and reliability in your application.
In the context of K8s, a load balancer can be set up using a K8s Service of type LoadBalancer or an Ingress resource that leverages an external load balancer.
Different load balancing solutions may have different limitations on the number of backend servers they can manage. These limitations can be due to resource constraints, software limitations, or restrictions imposed by the cloud provider.
