#### My ClusterIP does not respond to ping

#### Why is my Layer-4 Load Balancer in `Pending` state?
### Why is my Layer-4 Load Balancer in `Pending` state?
The Layer-4 Load Balancer is created as `type: LoadBalancer`. In Kubernetes, this needs a cloud provider or controller that can satisfy these requests, otherwise these will be in `Pending` state forever. More information can be found on [Cloud Providers]({{< baseurl >}}/rancher/v2.x/en/concepts/clusters/cloud-providers/) or [Create External Load Balancer](https://kubernetes.io/docs/tasks/access-application-cluster/create-external-load-balancer/)

### How can I automate task X in Rancher?
The UI consists of static files, and works based on responses of the API. That means every action/task that you can execute in the UI, can be automated via the API. There are 2 ways to do this:
* Visit `https://your_rancher_ip/v3` and browse the API options.
* Capture the API calls when using the UI (Most commonly used for this is [Chrome Developer Tools](https://developers.google.com/web/tools/chrome-devtools/#network) but you can use anything you like)
