{{< warning >}} This document configures Istio using Gateway API features that are experimental Before using the Gateway API instructions, make sure to:

1. Install the experimental version of the Gateway API CRDs:

   {{< text syntax=bash snip_id=install_experimental_crds >}} $ kubectl kustomize "github.com/kubernetes-sigs/gateway-api/config/crd/experimental?ref={{< k8s_gateway_api_version >}}" | kubectl apply -f - {{< /text >}}

2. Configure Istio to read the alpha Gateway API resources by setting the PILOT_ENABLE_ALPHA_GATEWAY_API environment variable to true when installing Istio:

   {{< text syntax=bash snip_id=enable_alpha_crds >}} $ istioctl install --set values.pilot.env.PILOT_ENABLE_ALPHA_GATEWAY_API=true --set profile=minimal -y {{< /text >}}
