description: Spec indicates the behavior of a destination rule.
properties:
export_to:
description: "A list of namespaces to which this destination rule is exported. The resolution of a destination rule to apply to a service occurs in the context of a hierarchy of namespaces. Exporting a destination rule allows it to be included in the resolution hierarchy for services in other namespaces. This feature provides a mechanism for service owners and mesh administrators to control the visibility of destination rules across namespace boundaries. \n If no namespaces are specified then the destination rule is exported to all namespaces by default. \n The value \".\" is reserved and defines an export to the same namespace that the destination rule is declared in. Similarly, the value \"*\" is reserved and defines an export to all namespaces. \n NOTE: in the current release, the `exportTo` value is restricted to \".\" or \"*\" (i.e., the current namespace or all namespaces)."

host:
description: "The name of a service from the service registry. Service names are looked up from the platform's service registry (e.g., Kubernetes services, Consul services, etc.) and from the hosts declared by [ServiceEntries](https://istio.io/docs/reference/config/networking/service-entry/#ServiceEntry). Rules defined for services that do not exist in the service registry will be ignored. \n *Note for Kubernetes users*: When short names are used (e.g. \"reviews\" instead of \"reviews.default.svc.cluster.local\"), Istio will interpret the short name based on the namespace of the rule, not the service. A rule in the \"default\" namespace containing a host \"reviews\" will be interpreted as \"reviews.default.svc.cluster.local\", irrespective of the actual namespace associated with the reviews service. _To avoid potential misconfigurations, it is recommended to always use fully qualified domain names over short names._ \n Note that the host field applies to both HTTP and TCP services."

subsets:
description: One or more named sets that represent individual versions of a service. Traffic policies can be overridden at subset level.
items:
description: "A subset of endpoints of a service. Subsets can be used for scenarios like A/B testing, or routing to a specific version of a service. Refer to [VirtualService](https://istio.io/docs/reference/config/networking/virtual-service/#VirtualService) documentation for examples of using subsets in these scenarios. In addition, traffic policies defined at the service-level can be overridden at a subset-level. The following rule uses a round robin load balancing policy for all traffic going to a subset named testversion that is composed of endpoints (e.g., pods) with labels (version:v3). \n {{<tabset category-name=\"example\">}} {{<tab name=\"v1alpha3\" category-value=\"v1alpha3\">}} ```yaml apiVersion: networking.istio.io/v1alpha3 kind: DestinationRule metadata: name: bookinfo-ratings spec: host: ratings.prod.svc.cluster.local trafficPolicy: loadBalancer: simple: LEAST_CONN subsets: - name: testversion labels: version: v3 trafficPolicy: loadBalancer: simple: ROUND_ROBIN ``` {{</tab>}} \n {{<tab name=\"v1beta1\" category-value=\"v1beta1\">}} ```yaml apiVersion: networking.istio.io/v1beta1 kind: DestinationRule metadata: name: bookinfo-ratings spec: host: ratings.prod.svc.cluster.local trafficPolicy: loadBalancer: simple: LEAST_CONN subsets: - name: testversion labels: version: v3 trafficPolicy: loadBalancer: simple: ROUND_ROBIN ``` {{</tab>}} {{</tabset>}} \n **Note:** Policies specified for subsets will not take effect until a route rule explicitly sends traffic to this subset. \n One or more labels are typically required to identify the subset destination, however, when the corresponding DestinationRule represents a host that supports multiple SNI hosts (e.g., an egress gateway), a subset without labels may be meaningful. In this case a traffic policy with [ClientTLSSettings](#ClientTLSSettings) can be used to identify a specific SNI host corresponding to the named subset."

This feature provides a mechanism for service owners and mesh administrators to control the visibility of virtual services across namespace boundaries. \n If no namespaces are specified then the virtual service is exported to all namespaces by default. \n The value \".\" is reserved and defines an export to the same namespace that the virtual service is declared in. Similarly the value \"*\" is reserved and defines an export to all namespaces. \n NOTE: in the current release, the `exportTo` value is restricted to \".\" or \"*\" (i.e., the current namespace or all namespaces)."

description: The names of gateways and sidecars that should apply these routes. Gateways in other namespaces may be referred to by `<gateway namespace>/<gateway name>`; specifying a gateway with no namespace qualifier is the same as specifying the VirtualService's namespace. A single VirtualService is used for sidecars inside the mesh as well as for one or more gateways. The selection condition imposed by this field can be overridden using the source field in the match conditions of protocol-specific routes. The reserved word `mesh` is used to imply all the sidecars in the mesh. When this field is omitted, the default gateway (`mesh`) will be used, which would apply the rule to all sidecars in the mesh. If a list of gateway names is provided, the rules will apply only to the gateways. To apply the rules to both gateways and sidecars, specify `mesh` as one of the gateway names.

Depending on the platform, short-names can also be used instead of a FQDN (i.e. has no dots in the name). In such a scenario, the FQDN of the host would be derived based on the underlying platform. \n A single VirtualService can be used to describe all the traffic properties of the corresponding hosts, including those for multiple HTTP and TCP ports. Alternatively, the traffic properties of a host can be defined using more than one VirtualService, with certain caveats. Refer to the [Operations Guide](https://istio.io/docs/ops/best-practices/traffic-management/#split-virtual-services) for details. \n *Note for Kubernetes users*: When short names are used (e.g. \"reviews\" instead of \"reviews.default.svc.cluster.local\"), Istio will interpret the short name based on the namespace of the rule, not the service. A rule in the \"default\" namespace containing a host \"reviews\" will be interpreted as \"reviews.default.svc.cluster.local\", irrespective of the actual namespace associated with the reviews service. _To avoid potential misconfigurations, it is recommended to always use fully qualified domain names over short names._ \n The hosts field applies to both HTTP and TCP services. Service inside the mesh, i.e., those found in the service registry, must always be referred to using their alphanumeric names. IP addresses are allowed only for services defined via the Gateway. \n *Note*: It must be empty for a delegate VirtualService."
