LoadBalancer Service EXTERNAL-IP pending state¶

In Kubernetes environments, the LoadBalancer Service EXTERNAL-IP pending state is a status observed when a Service of type LoadBalancer is created, but the external IP address has not yet been assigned or provisioned by the cloud provider or the cluster's network infrastructure.^[400-devops__06-Kubernetes__k8s-learning__06.ingress__README.md]

Service Status¶

When a Service is defined as LoadBalancer, Kubernetes attempts to contact an external load balancer (such as those provided by cloud providers) to allocate an IP address.^[400-devops__06-Kubernetes__k8s-learning__06.ingress__README.md] Until this allocation process is complete, the EXTERNAL-IP field in the service configuration will display <pending>.^[400-devops__06-Kubernetes__k8s-learning__06.ingress__README.md]

For example, upon deploying an Ingress Controller, the EXTERNAL-IP may initially show as <pending>^[400-devops__06-Kubernetes__k8s-learning__06.ingress__README.md]:

NAME                       TYPE           EXTERNAL-IP   PORT(S)
ingress-nginx-controller   LoadBalancer   <pending>     80:32411/TCP,443:30176/TCP

Causes¶

The <pending> status typically indicates that the Kubernetes cluster is unable to configure a load balancer^[400-devops__06-Kubernetes__k8s-learning__06.ingress__README.md]. This situation usually arises because the underlying environment does not natively support Services of type LoadBalancer^[400-devops__06-Kubernetes__k8s-learning__06.ingress__README.md].

This is a common occurrence in local development clusters or bare-metal setups that lack an integration with a cloud provider's load balancer controller^[400-devops__06-Kubernetes__k8s-learning__06.ingress__README.md]. "Real" cloud-hosted clusters will typically assign an IP address or FQDN automatically^[400-devops__06-Kubernetes__k8s-learning__06.ingress__README.md].
