## Cutomize kourier-bootstrap for Kourier gateways:
By default, Kourier contains envoy bootstrap configuration in the ConfigMap `kourier-bootstrap`. The `spec.ingress.kourier.bootstrap-configmap` field allows you to specify your customized bootstrap ConfigMap.
This example shows that Kourier Gateawy uses `my-configmap` for the envoy bootstrap config.
```yaml
apiVersion: operator.knative.dev/v1beta1
kind: KnativeServing
metadata:
name: knative-serving
namespace: knative-serving
spec:
config:
network:
ingress-class: kourier.ingress.networking.knative.dev
ingress:
kourier:
bootstrap-configmap: my-configmap
enabled: true
```
## High availability
By default, Knative Serving runs a single instance of each deployment. The `spec.high-availability` field allows you to configure the number of replicas for all deployments managed by the operator.
