type IngressGatewayValues

type IngressGatewayValues struct {
	Annotations           map[string]string
	Labels                map[string]string
	ExternalTrafficPolicy *corev1.ServiceExternalTrafficPolicyType

	Ports []corev1.ServicePort
}

	Namespace string
	// Image is the image used for the `istiod` deployment.
	Image string
	// TrustDomain is the domain used for service discovery, e.g. `cluster.local`.
	TrustDomain string
	// Zones are the availability zones used for this `istiod` deployment.
	Zones []string
}

IstiodValues contains configuration values for the Istiod component.

type Values

type Values struct {
	// Istiod are configuration values for the istiod chart.
	Istiod IstiodValues
	// IngressGateway are configuration values for ingress gateway deployments and objects.
	IngressGateway []IngressGatewayValues
	// Suffix can be used to append arbitrary identifiers to resources which are deployed to common namespaces.
	Suffix string
}
