Visit https://www.envoyproxy.io/docs/envoy/latest/api-v3/config/bootstrap/v3/bootstrap.proto#envoy-v3-api-msg-config-bootstrap-v3-bootstrap to learn more about the syntax. If set, this is the Bootstrap configuration used for the managed Envoy Proxy fleet instead of the default Bootstrap configuration set by Envoy Gateway. Some fields within the Bootstrap that are required to communicate with the xDS Server (Envoy Gateway) and receive xDS resources from it are not configurable and will result in the EnvoyProxy resource being rejected. Backward compatibility across minor versions is not guaranteed. We strongly recommend using egctl x translate to generate a EnvoyProxy resource with the Bootstrap field set to the default Bootstrap configuration used. You can edit this configuration, and rerun egctl x translate to ensure there are no validation errors.
