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."
type: string
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."

failover:
description: 'Optional: only failover or distribute can be set. Explicitly specify the region traffic will land on when endpoints in local region becomes unhealthy. Should be used together with OutlierDetection to detect unhealthy endpoints. Note: if no OutlierDetection specified, this will not take effect.'
items:
description: Specify the traffic failover policy across regions. Since zone and sub-zone failover is supported by default this only needs to be specified for regions when the operator needs to constrain traffic failover so that the default behavior of failing over to any endpoint globally does not apply. This is useful when failing over traffic across regions would not improve service health or may need to be restricted for other reasons like regulatory controls.

This technique allows the system to automatically increase the ejection period for unhealthy upstream servers. format: 1h/1m/1s/1ms. MUST BE >=1ms. Default is 30s.'
properties:
nanos:
description: Signed fractions of a second at nanosecond resolution of the span of time. Durations less than one second are represented with a 0 `seconds` field and a positive or negative `nanos` field. For durations of one second or more, a non-zero value for the `nanos` field must be of the same sign as the `seconds` field. Must be from -999,999,999 to +999,999,999 inclusive.

consecutive_5xx_errors:
description: "Number of 5xx errors before a host is ejected from the connection pool. When the upstream host is accessed over an opaque TCP connection, connect timeouts, connection error/failure and request failure events qualify as a 5xx error. This feature defaults to 5 but can be disabled by setting the value to 0. \n Note that consecutive_gateway_errors and consecutive_5xx_errors can be used separately or together. Because the errors counted by consecutive_gateway_errors are also included in consecutive_5xx_errors, if the value of consecutive_gateway_errors is greater than or equal to the value of consecutive_5xx_errors, consecutive_gateway_errors will have no effect."

min_health_percent:
description: Outlier detection will be enabled as long as the associated load balancing pool has at least min_health_percent hosts in healthy mode. When the percentage of healthy hosts in the load balancing pool drops below this threshold, outlier detection will be disabled and the proxy will load balance across all hosts in the pool (healthy and unhealthy). The threshold can be disabled by setting it to 0%. The default is 0% as it's not typically applicable in k8s environments with few pods per service.
