Appears in:
| Field | Description |

gateway Gateway | Gateway defines desired Gateway API specific configuration. If unset, default configuration parameters will apply. |
provider EnvoyGatewayProvider | Provider defines the desired provider and provider-specific configuration. If unspecified, the Kubernetes provider is used with default configuration parameters. |
rateLimit RateLimit | RateLimit defines the configuration associated with the Rate Limit service deployed by Envoy Gateway required to implement the Global Rate limiting functionality. The specific rate limit service used here is the reference implementation in Envoy. For more details visit https://github.com/envoyproxy/ratelimit. This configuration is unneeded for “Local” rate limiting. |
extension Extension | Extension defines an extension to register for the Envoy Gateway Control Plane. |

| Field | Description |
|---|---|
apiVersion string | config.gateway.envoyproxy.io/v1alpha1 |

metadata ObjectMeta | Refer to Kubernetes API documentation for fields of metadata. |
spec EnvoyProxySpec | EnvoyProxySpec defines the desired state of EnvoyProxy. |
EnvoyProxyKubernetesProvider
EnvoyProxyKubernetesProvider defines configuration for the Kubernetes resource provider.
Appears in:
| Field | Description |
|---|---|
envoyDeployment KubernetesDeploymentSpec | EnvoyDeployment defines the desired state of the Envoy deployment resource. If unspecified, default settings for the managed Envoy deployment resource are applied. |
envoyService KubernetesServiceSpec | EnvoyService defines the desired state of the Envoy service resource. If unspecified, default settings for the managed Envoy service resource are applied. |
EnvoyProxyProvider
EnvoyProxyProvider defines the desired state of a resource provider.
Appears in:
| Field | Description |
|---|---|
type ProviderType | Type is the type of resource provider to use. A resource provider provides infrastructure resources for running the data plane, e.g. Envoy proxy, and optional auxiliary control planes. Supported types are “Kubernetes”. |
kubernetes EnvoyProxyKubernetesProvider | Kubernetes defines the desired state of the Kubernetes resource provider. Kubernetes provides infrastructure resources for running the data plane, e.g. Envoy proxy. If unspecified and type is “Kubernetes”, default settings for managed Kubernetes resources are applied. |
EnvoyProxySpec
EnvoyProxySpec defines the desired state of EnvoyProxy.
Appears in:
| Field | Description |
|---|---|
provider EnvoyProxyProvider | Provider defines the desired resource provider and provider-specific configuration. If unspecified, the “Kubernetes” resource provider is used with default configuration parameters. |
logging ProxyLogging | Logging defines logging parameters for managed proxies. If unspecified, default settings apply. This type is not implemented until https://github.com/envoyproxy/gateway/issues/280 is fixed. |
bootstrap string | Bootstrap defines the Envoy Bootstrap as a YAML string. 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. |
