type Any 

type Any struct {
	// A URL/resource name whose content describes the type of the
	// serialized protocol buffer message.
	//
	// For URLs which use the scheme `http`, `https`, or no scheme, the
	// following restrictions and interpretations apply:
	//
	// * If no scheme is provided, `https` is assumed.
	// * The last segment of the URL's path must represent the fully
	//   qualified name of the type (as in `path/google.protobuf.Duration`).
	//   The name should be in a canonical form (e.g., leading "." is
	//   not accepted).
	// * An HTTP GET on the URL must yield a [google.protobuf.Type][]
	//   value in binary format, or produce an error.
	// * Applications are allowed to cache lookup results based on the
	//   URL, or have them precompiled into a binary to avoid any
	//   lookup. Therefore, binary compatibility needs to be preserved
	//   on changes to types. (Use versioned type names to manage
	//   breaking changes.)
	//
	// Schemes other than `http`, `https` (or the empty scheme) might be
	// used with implementation specific semantics.
	//
	TypeUrl string `protobuf:"bytes,1,opt,name=type_url,proto3" json:"type_url,omitempty"`
	// Must be a valid serialized protocol buffer of the above specified type.
	Value []byte `protobuf:"bytes,2,opt,name=value,proto3" json:"value,omitempty"`
}

`Any` contains an arbitrary serialized protocol buffer message along with a URL that describes the type of the serialized message.

Protobuf library provides support to pack/unpack Any values in the form of utility functions or additional generated methods of the Any type.

Example 1: Pack and unpack a message in C++. 

Foo foo = ...;
Any any;
any.PackFrom(foo);
...
if (any.UnpackTo(&foo)) {
  ...
}

Example 2: Pack and unpack a message in Java. 

   Foo foo = ...;
   Any any = Any.pack(foo);
   ...
   if (any.is(Foo.class)) {
     foo = any.unpack(Foo.class);
   }

Example 3: Pack and unpack a message in Python.

   foo = Foo(...)
   any = Any()
   any.Pack(foo)
   ...
   if any.Is(Foo.DESCRIPTOR):
     any.Unpack(foo)
     ...

Example 4: Pack and unpack a message in Go

    foo := &pb.Foo{...}
    any, err := ptypes.MarshalAny(foo)
    ...
    foo := &pb.Foo{}
    if err := ptypes.UnmarshalAny(any, foo); err != nil {
      ...
    }

The pack methods provided by protobuf library will by default use 'type.googleapis.com/full.type.name' as the type URL and the unpack methods only use the fully qualified type name after the last '/' in the type URL, for example "foo.bar.com/x/y.z" will yield type name "y.z".

JSON ==== The JSON representation of an `Any` value uses the regular representation of the deserialized, embedded message, with an additional field `@type` which contains the type URL. Example: 

package google.profile;
message Person {
  string first_name = 1;
  string last_name = 2;
}

{
  "@type": "type.googleapis.com/google.profile.Person",
  "firstName": <string>,
  "lastName": <string>
}

If the embedded message type is well-known and has a custom JSON representation, that representation will be embedded adding a field `value` which holds the custom JSON in addition to the `@type` field. Example (for message [google.protobuf.Duration][]): 

{
  "@type": "type.googleapis.com/google.protobuf.Duration",
  "value": "1.212s"
}

type ClusterLoadAssignment 

type ClusterLoadAssignment struct {
	// Name of the cluster. This will be the :ref:`service_name
	// <envoy_api_field_Cluster.EdsClusterConfig.service_name>` value if specified
	// in the cluster :ref:`EdsClusterConfig

	// List of endpoints to load balance to.
	Endpoints []*LocalityLbEndpoints `protobuf:"bytes,2,rep,name=endpoints" json:"endpoints,omitempty"`
}

Each route from RDS will map to a single cluster or traffic split across clusters using weights expressed in the RDS WeightedCluster.

With EDS, each cluster is treated independently from a LB perspective, with LB taking place between the Localities within a cluster and at a finer granularity between the hosts within a locality. For a given cluster, the effective weight of a host is its load_balancing_weight multiplied by the load_balancing_weight of its Locality.

type ConnectionPoolSettings 

type ConnectionPoolSettings struct {
	// Settings common to both HTTP and TCP upstream connections.
	Tcp *ConnectionPoolSettings_TCPSettings `protobuf:"bytes,1,opt,name=tcp" json:"tcp,omitempty"`
	// HTTP connection pool settings.
	Http *ConnectionPoolSettings_HTTPSettings `protobuf:"bytes,2,opt,name=http" json:"http,omitempty"`
}

Connection pool settings for an upstream host. The settings apply to each individual host in the upstream service. See Envoy's [circuit breaker](https://www.envoyproxy.io/docs/envoy/latest/intro/arch_overview/circuit_breaking) for more details. Connection pool settings can be applied at the TCP level as well as at HTTP level.

For example, the following rule sets a limit of 100 connections to redis service called myredissrv with a connect timeout of 30ms 

apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:
  name: bookinfo-redis

Describes the Cross-Origin Resource Sharing (CORS) policy, for a given service. Refer to https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS for further details about cross origin resource sharing. For example, the following rule restricts cross origin requests to those originating from example.com domain using HTTP POST/GET, and sets the Access-Control-Allow-Credentials header to false. In addition, it only exposes X-Foo-bar header and sets an expiry period of 1 day.

type Destination 

type Destination struct {

	// Kubernetes services, Consul services, etc.) and from the hosts
	// declared by [ServiceEntry](#ServiceEntry). Traffic forwarded to

	//
	// *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._
	Host string `protobuf:"bytes,1,opt,name=host,proto3" json:"host,omitempty"`
	// The name of a subset within the service. Applicable only to services
	// within the mesh. The subset must be defined in a corresponding
	// DestinationRule.
	Subset string `protobuf:"bytes,2,opt,name=subset,proto3" json:"subset,omitempty"`
	// Specifies the port on the host that is being addressed. Many services
	// only expose a single port or label ports with the protocols they support,
	// in these cases it is not required to explicitly select the port. Note that
	// selection priority is to first match by name and then match by number.
	//
	// Names must comply with DNS label syntax (rfc1035) and therefore cannot
	// collide with numbers. If there are multiple ports on a service with
	// the same protocol the names should be of the form <protocol-name>-<DNS
	// label>.
	Port *PortSelector `protobuf:"bytes,3,opt,name=port" json:"port,omitempty"`
}

Destination indicates the network addressable service to which the request/connection will be sent after processing a routing rule. The destination.host should unambiguously refer to a service in the service registry. Istio's service registry is composed of all the services found in the platform's service registry (e.g., Kubernetes services, Consul services), as well as services declared through the ServiceEntry(#ServiceEntry) resource.

*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._

The following Kubernetes example routes all traffic by default to pods of the reviews service with label "version: v1" (i.e., subset v1), and some to subset v2, in a kubernetes environment. 

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: reviews-route
  namespace: foo
spec:
  hosts:
  - reviews # interpreted as reviews.foo.svc.cluster.local
  http:
  - match:
    - uri:
        prefix: "/wpcatalog"
    - uri:
        prefix: "/consumercatalog"
    rewrite:
      uri: "/newcatalog"
    route:
    - destination:
        host: reviews # interpreted as reviews.foo.svc.cluster.local
        subset: v2
  - route:
    - destination:
        host: reviews # interpreted as reviews.foo.svc.cluster.local
        subset: v1

And the associated DestinationRule 

apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:
  name: reviews-destination
  namespace: foo
spec:
  host: reviews # interpreted as reviews.foo.svc.cluster.local
  subsets:
  - name: v1
    labels:
      version: v1
  - name: v2
    labels:
      version: v2

The following VirtualService sets a timeout of 5s for all calls to productpage.prod.svc.cluster.local service in Kubernetes. Notice that there are no subsets defined in this rule. Istio will fetch all instances of productpage.prod.svc.cluster.local service from the service registry and populate the sidecar's load balancing pool. Also, notice that this rule is set in the dmesh namespace but uses the fully qualified domain name of the productpage service, productpage.prod.svc.cluster.local. Therefore the rule's namespace does not have an impact in resolving the name of the productpage service. 

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: my-productpage-rule
  namespace: dmesh
spec:
  hosts:
  - productpage.prod.svc.cluster.local # ignores rule namespace
  http:
  - timeout: 5s
    route:
    - destination:
        host: productpage.prod.svc.cluster.local

To control routing for traffic bound to services outside the mesh, external services must first be added to Istio's internal service registry using the ServiceEntry resource. VirtualServices can then be defined to control traffic bound to these external services. For example, the following rules define a Service for wikipedia.org and set a timeout of 5s for http requests. 

apiVersion: networking.istio.io/v1alpha3
kind: ServiceEntry
metadata:
  name: external-svc-wikipedia
spec:
  hosts:
  - wikipedia.org
  location: MESH_EXTERNAL
  ports:
  - number: 80
    name: example-http
    protocol: HTTP
  resolution: DNS

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: my-wiki-rule
spec:
  hosts:
  - wikipedia.org
  http:
  - timeout: 5s
    route:
    - destination:
        host: wikipedia.org

type DestinationRule 

type DestinationRule struct {
	// REQUIRED. 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](#ServiceEntry). Rules defined for

	//
	// *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._
	//
	// Note that the host field applies to both HTTP and TCP services.
	Host string `protobuf:"bytes,1,opt,name=host,proto3" json:"host,omitempty"`
	// Traffic policies to apply (load balancing policy, connection pool
	// sizes, outlier detection).
	TrafficPolicy *TrafficPolicy `protobuf:"bytes,2,opt,name=traffic_policy" json:"traffic_policy,omitempty"`
	// One or more named sets that represent individual versions of a
	// service. Traffic policies can be overridden at subset level.
	Subsets []*Subset `protobuf:"bytes,3,rep,name=subsets" json:"subsets,omitempty"`
}

`DestinationRule` defines policies that apply to traffic intended for a service after routing has occurred. These rules specify configuration for load balancing, connection pool size from the sidecar, and outlier detection settings to detect and evict unhealthy hosts from the load balancing pool. For example, a simple load balancing policy for the ratings service would look as follows: 

apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:
  name: bookinfo-ratings
spec:
  host: ratings.prod.svc.cluster.local
  trafficPolicy:
    loadBalancer:
      simple: LEAST_CONN

Version specific policies can be specified by defining a named `subset` and overriding the settings specified at the service 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). 

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

**Note:** Policies specified for subsets will not take effect until a route rule explicitly sends traffic to this subset.

Traffic policies can be customized to specific ports as well. The following rule uses the least connection load balancing policy for all traffic to port 80, while uses a round robin load balancing setting for traffic to the port 9080. 

apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:
  name: bookinfo-ratings-port
spec:
  host: ratings.prod.svc.cluster.local
  trafficPolicy: # Apply to all ports

type DestinationWeight struct {
	// REQUIRED. Destination uniquely identifies the instances of a service
	// to which the request/connection should be forwarded to.
	Destination *Destination `protobuf:"bytes,1,opt,name=destination" json:"destination,omitempty"`
	// REQUIRED. The proportion of traffic to be forwarded to the service
	// version. (0-100). Sum of weights across destinations SHOULD BE == 100.
	// If there is only destination in a rule, the weight value is assumed to
	// be 100.
	Weight int32 `protobuf:"varint,2,opt,name=weight,proto3" json:"weight,omitempty"`
}

Each routing rule is associated with one or more service versions (see glossary in beginning of document). Weights associated with the version determine the proportion of traffic it receives. For example, the following rule will route 25% of traffic for the "reviews" service to instances with the "v2" tag and the remaining traffic (i.e., 75%) to "v1". 

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: reviews-route
spec:
  hosts:
  - reviews.prod.svc.cluster.local
  http:
  - route:
    - destination:
        host: reviews.prod.svc.cluster.local
        subset: v2
      weight: 25
    - destination:
        host: reviews.prod.svc.cluster.local
        subset: v1
      weight: 75

And the associated DestinationRule 

apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:

  subsets:
  - name: v1
    labels:
      version: v1
  - name: v2
    labels:
      version: v2

Traffic can also be split across two entirely different services without having to define new subsets. For example, the following rule forwards 25% of traffic to reviews.com to dev.reviews.com 

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: reviews-route-two-domains
spec:

type Duration 

type Duration struct {
	// Signed seconds of the span of time. Must be from -315,576,000,000
	// to +315,576,000,000 inclusive. Note: these bounds are computed from:

	Seconds int64 `protobuf:"varint,1,opt,name=seconds,proto3" json:"seconds,omitempty"`
	// 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.
	Nanos int32 `protobuf:"varint,2,opt,name=nanos,proto3" json:"nanos,omitempty"`
}

A Duration represents a signed, fixed-length span of time represented as a count of seconds and fractions of seconds at nanosecond resolution. It is independent of any calendar and concepts like "day" or "month". It is related to Timestamp in that the difference between two Timestamp values is a Duration and it can be added or subtracted from a Timestamp. Range is approximately +-10,000 years.

Examples

Example 1: Compute Duration from two Timestamps in pseudo code. 

Timestamp start = ...;
Timestamp end = ...;
Duration duration = ...;

duration.seconds = end.seconds - start.seconds;
duration.nanos = end.nanos - start.nanos;

if (duration.seconds < 0 && duration.nanos > 0) {
  duration.seconds += 1;
  duration.nanos -= 1000000000;
} else if (durations.seconds > 0 && duration.nanos < 0) {
  duration.seconds -= 1;
  duration.nanos += 1000000000;
}

Example 2: Compute Timestamp from Timestamp + Duration in pseudo code. 

Timestamp start = ...;
Duration duration = ...;
Timestamp end = ...;

end.seconds = start.seconds + duration.seconds;
end.nanos = start.nanos + duration.nanos;

if (end.nanos < 0) {
  end.seconds -= 1;
  end.nanos += 1000000000;
} else if (end.nanos >= 1000000000) {
  end.seconds += 1;
  end.nanos -= 1000000000;
}

Example 3: Compute Duration from datetime.timedelta in Python. 

td = datetime.timedelta(days=3, minutes=10)
duration = Duration()
duration.FromTimedelta(td)

JSON Mapping

In JSON format, the Duration type is encoded as a string rather than an object, where the string ends in the suffix "s" (indicating seconds) and is preceded by the number of seconds, with nanoseconds expressed as fractional seconds. For example, 3 seconds with 0 nanoseconds should be encoded in JSON format as "3s", while 3 seconds and 1 nanosecond should be expressed in JSON format as "3.000000001s", and 3 seconds and 1 microsecond should be expressed in JSON format as "3.000001s".

}

`Gateway` describes a load balancer operating at the edge of the mesh receiving incoming or outgoing HTTP/TCP connections. The specification describes a set of ports that should be exposed, the type of protocol to use, SNI configuration for the load balancer, etc.

For example, the following Gateway configuration sets up a proxy to act as a load balancer exposing port 80 and 9080 (http), 443 (https), and port 2379 (TCP) for ingress. The gateway will be applied to the proxy running on a pod with labels `app: my-gateway-controller`. While Istio will configure the proxy to listen on these ports, it is the responsibility of the user to ensure that external traffic to these ports are allowed into the mesh.

      protocol: MONGO

The Gateway specification above describes the L4-L6 properties of a load balancer. A `VirtualService` can then be bound to a gateway to control the forwarding of traffic arriving at a particular host or gateway port.

For example, the following VirtualService splits traffic for "https://uk.bookinfo.com/reviews", "https://eu.bookinfo.com/reviews", "http://uk.bookinfo.com:9080/reviews", "http://eu.bookinfo.com:9080/reviews" into two versions (prod and qa) of an internal reviews service on port 9080. In addition, requests containing the cookie "user: dev-123" will be sent to special port 7777 in the qa version. The same rule is also applicable inside the mesh for requests to the r"eviews.prod.svc.cluster.local" service. This rule is applicable across ports 443, 9080. Note that "http://uk.bookinfo.com" gets redirected to "https://uk.bookinfo.com" (i.e. 80 redirects to 443). 

apiVersion: networking.istio.io/v1alpha3

      weight: 80
    - destination:
        name: reviews.qa.svc.cluster.local
      weight: 20

The following VirtualService forwards traffic arriving at (external) port 27017 from "172.17.16.0/24" subnet to internal Mongo server on port 5555. This rule is not applicable internally in the mesh as the gateway list omits the reserved name `mesh`.

HTTPFaultInjection can be used to specify one or more faults to inject while forwarding http requests to the destination specified in a route. Fault specification is part of a VirtualService rule. Faults include aborting the Http request from downstream service, and/or delaying proxying of requests. A fault rule MUST HAVE delay or abort or both.

*Note:* Delay and abort faults are independent of one another, even if both are specified simultaneously.

Delay specification is used to inject latency into the request forwarding path. The following example will introduce a 5 second delay in 10% of the requests to the "v1" version of the "reviews" service from all pods with label env: prod 

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: reviews-route
spec:
  hosts:
  - reviews.prod.svc.cluster.local
  http:
  - match:

        subset: v1
    fault:
      delay:
        percent: 10
        fixedDelay: 5s

The _fixedDelay_ field is used to indicate the amount of delay in seconds. An optional _percent_ field, a value between 0 and 100, can be used to only delay a certain percentage of requests. If left unspecified, all request will be delayed.

	Authority string `protobuf:"bytes,2,opt,name=authority,proto3" json:"authority,omitempty"`
}

HTTPRedirect can be used to send a 302 redirect response to the caller, where the Authority/Host and the URI in the response can be swapped with the specified values. For example, the following rule redirects requests for /v1/getProductRatings API on the ratings service to /v1/bookRatings provided by the bookratings service. 

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:

Load balancing policies to apply for a specific destination. See Envoy's load balancing [documentation](https://www.envoyproxy.io/docs/envoy/latest/intro/arch_overview/load_balancing.html) for more details.

For example, the following rule uses a round robin load balancing policy for all traffic going to the ratings service.

	FilterMetadata map[string]*Struct `` /* 157-byte string literal not displayed */
}

Metadata provides additional inputs to filters based on matched listeners, filter chains, routes and endpoints. It is structured as a map from filter name (in reverse DNS format) to metadata specific to the filter. Metadata key-values for a filter are merged as connection and request handling occurs, with later values for the same key overriding earlier values.

An example use of metadata is providing additional values to http_connection_manager in the envoy.http_connection_manager.access_log namespace.

For load balancing, Metadata provides a means to subset cluster endpoints. Endpoints have a Metadata object associated and routes contain a Metadata object to match against. There are some well defined metadata used today for this purpose:

  • “{"envoy.lb": {"canary": <bool> }}“ This indicates the canary status of an endpoint and is also used during header processing (x-envoy-upstream-canary) and for stats purposes.

A Circuit breaker implementation that tracks the status of each individual host in the upstream service. While currently applicable to only HTTP services, future versions will support opaque TCP services as well. For HTTP services, hosts that continually return errors for API calls are ejected from the pool for a pre-defined period of time. See Envoy's [outlier detection](https://www.envoyproxy.io/docs/envoy/latest/intro/arch_overview/outlier) for more details.

The following rule sets a connection pool size of 100 connections and 1000 concurrent HTTP2 requests, with no more than 10 req/connection to "reviews" service. In addition, it configures upstream hosts to be scanned every 5 mins, such that any host that fails 7 consecutive times with 5XX error code will be ejected for 15 minutes.

`ServiceEntry` enables adding additional entries into Istio's internal service registry, so that auto-discovered services in the mesh can access/route to these manually specified services. A service entry describes the properties of a service (DNS name, VIPs ,ports, protocols, endpoints). These services could be external to the mesh (e.g., web APIs) or mesh-internal services that are not part of the platform's service registry (e.g., a set of VMs talking to services in Kubernetes).

The following configuration adds a set of MongoDB instances running on unmanaged VMs to Istio's registry, so that these services can be treated as any other service in the mesh. The associated DestinationRule is used to initiate mTLS connections to the database instances. 

apiVersion: networking.istio.io/v1alpha3
kind: ServiceEntry
metadata:
  name: external-svc-mongocluster
spec:
  hosts:
  - mymongodb.somedomain # not used
  addresses:
  - 192.192.192.192/24 # VIPs
  ports:
  - number: 27018
    name: mongodb
    protocol: MONGO
  location: MESH_INTERNAL
  resolution: STATIC
  endpoints:
  - address: 2.2.2.2
  - address: 3.3.3.3

and the associated DestinationRule 

apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:
  name: mtls-mongocluster
spec:
  host: mymongodb.somedomain
  trafficPolicy:
    tls:
      mode: MUTUAL
      clientCertificate: /etc/certs/myclientcert.pem
      privateKey: /etc/certs/client_private_key.pem
      caCertificates: /etc/certs/rootcacerts.pem

The following example demonstrates the use of wildcards in the hosts for external services. If the connection has to be routed to the IP address requested by the application (i.e. application resolves DNS and attempts to connect to a specific IP), the discovery mode must be set to `NONE`. 

apiVersion: networking.istio.io/v1alpha3
kind: ServiceEntry
metadata:
  name: external-svc-wildcard-example
spec:
  hosts:
  - "*.bar.com"
  location: MESH_EXTERNAL
  ports:
  - number: 80
    name: http
    protocol: HTTP
  resolution: NONE

For HTTP based services, it is possible to create a VirtualService backed by multiple DNS addressable endpoints. In such a scenario, the application can use the HTTP_PROXY environment variable to transparently reroute API calls for the VirtualService to a chosen backend. For example, the following configuration creates a non-existent external service called foo.bar.com backed by three domains: us.foo.bar.com:8443, uk.foo.bar.com:9443, and in.foo.bar.com:7443 

apiVersion: networking.istio.io/v1alpha3
kind: ServiceEntry
metadata:
  name: external-svc-dns
spec:
  hosts:
  - foo.bar.com
  location: MESH_EXTERNAL
  ports:
  - number: 443
    name: https
    protocol: HTTP
  resolution: DNS
  endpoints:
  - address: us.foo.bar.com
    ports:
      https: 8443
  - address: uk.foo.bar.com
    ports:
      https: 9443
  - address: in.foo.bar.com
    ports:
      https: 7443

and a DestinationRule to initiate TLS connections to the ServiceEntry. 

apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:
  name: tls-foobar
spec:
  host: foo.bar.com
  trafficPolicy:
    tls:
      mode: SIMPLE # initiates HTTPS

With HTTP_PROXY=http://localhost:443, calls from the application to http://foo.bar.com will be upgraded to HTTPS and load balanced across the three domains specified above. In other words, a call to http://foo.bar.com/baz would be translated to https://uk.foo.bar.com/baz.

	Code int32 `protobuf:"varint,1,opt,name=code,proto3" json:"code,omitempty"`
	// A developer-facing error message, which should be in English. Any

	// message types for APIs to use.
	// google.protobuf.Any
	Details []*Any `protobuf:"bytes,3,rep,name=details" json:"details,omitempty"`
}

The `Status` type defines a logical error model that is suitable for different programming environments, including REST APIs and RPC APIs. It is used by [gRPC](https://github.com/grpc). The error model is designed to be:

- Simple to use and understand for most users - Flexible enough to meet unexpected needs

Overview

The `Status` message contains three pieces of data: error code, error message, and error details. The error code should be an enum value of [google.rpc.Code][google.rpc.Code], but it may accept additional error codes if needed. The error message should be a developer-facing English message that helps developers *understand* and *resolve* the error. If a localized user-facing error message is needed, put the localized message in the error details or localize it in the client. The optional error details may contain arbitrary information about the error. There is a predefined set of error detail types in the package `google.rpc` that can be used for common error conditions.

Language mapping

The `Status` message is the logical representation of the error model, but it is not necessarily the actual wire format. When the `Status` message is exposed in different client libraries and different wire protocols, it can be mapped differently. For example, it will likely be mapped to some exceptions in Java, but more likely mapped to some error codes in C.

Other uses

The error model and the `Status` message can be used in a variety of environments, either with or without APIs, to provide a consistent developer experience across different environments.

Example uses of this error model include:

  • Partial errors. If a service needs to return partial errors to the client, it may embed the `Status` in the normal response to indicate the partial errors.
  • Workflow errors. A typical workflow has multiple steps. Each step may have a `Status` message for error reporting.
  • Batch operations. If a client uses batch request and batch response, the `Status` message should be used directly inside batch response, one for each error sub-response.
  • Asynchronous operations. If an API call embeds asynchronous operation results in its response, the status of those operations should be represented directly using the `Status` message.
  • Logging. If some API errors are stored in logs, the message `Status` could be used directly after any stripping needed for security/privacy reasons.

For example, in scripting languages like JS a struct is represented as an object. The details of that representation are described together with the proto support for the language.

The JSON representation for `Struct` is JSON object.

	// dots in the name). In such a scenario, the FQDN of the host would be
	// derived based on the underlying platform.
	//
	// **A host name can be defined by only one VirtualService**. A single
	// VirtualService can be used to describe traffic properties for multiple
	// HTTP and TCP ports.
	//
	// *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._
	//
	// The hosts field applies to both HTTP and TCP services. Service inside

	// can be overridden using the source field in the match conditions of HTTP/TCP
	// 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

	// only to the gateways. To apply the rules to both gateways and sidecars,

}

A `VirtualService` defines a set of traffic routing rules to apply when a host is addressed. Each routing rule defines matching criteria for traffic of a specific protocol. If the traffic is matched, then it is sent to a named destination service (or subset/version of it) defined in the registry.

The source of traffic can also be matched in a routing rule. This allows routing to be customized for specific client contexts.

The following example on Kubernetes, routes all HTTP traffic by default to pods of the reviews service with label "version: v1". In addition, HTTP requests containing /wpcatalog/, /consumercatalog/ url prefixes will be rewritten to /newcatalog and sent to pods with label "version: v2". 

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: reviews-route
spec:
  hosts:
  - reviews.prod.svc.cluster.local
  http:
  - match:
    - uri:
        prefix: "/wpcatalog"
    - uri:
        prefix: "/consumercatalog"
    rewrite:
      uri: "/newcatalog"
    route:
    - destination:
        host: reviews.prod.svc.cluster.local
        subset: v2
  - route:
    - destination:
        host: reviews.prod.svc.cluster.local
        subset: v1

A subset/version of a route destination is identified with a reference to a named service subset which must be declared in a corresponding `DestinationRule`. 

apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:
  name: reviews-destination
spec:
  host: reviews.prod.svc.cluster.local
  subsets:
