Install the Backend custom resource

Before you can use the Backend custom resource, you must install its definition into your Kubernetes cluster.

1. Install the custom resource definition with kubectl apply:

   Community ingress controller

   $ kubectl apply -f https://cdn.haproxy.com/documentation/kubernetes/1.8/crd/backend.yaml
   

2. Verify that the installation worked by listing custom resources defined in your cluster:

   $ kubectl get crd
