Types

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

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

name: bookinfo-redis

spec: 

host: myredissrv.prod.svc.cluster.local
trafficPolicy:
  connectionPool:
    tcp:
      maxConnections: 100
      connectTimeout: 30ms

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.

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

name: ratings-route

spec: 

hosts:
- ratings.prod.svc.cluster.local
http:

type Destination 

type Destination 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 [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. If a service
	// exposes only a single port it is not required to explicitly select the
	// port.
	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.

```yaml 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

```yaml 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 istio-system 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.

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

name: my-productpage-rule
namespace: istio-system

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.

```yaml 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

	//
	// 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=trafficPolicy" 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:

```yaml 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).

```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

```

**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.

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

name: bookinfo-ratings-port

spec: 

host: ratings.prod.svc.cluster.local
trafficPolicy: # Apply to all ports
  portLevelSettings:
  - port:
      number: 80
    loadBalancer:
      simple: LEAST_CONN
  - port:
      number: 9080
    loadBalancer:
      simple: ROUND_ROBIN

type DestinationWeight 

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".

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

name: reviews-route

spec: 

hosts:
- reviews.prod.svc.cluster.local
http:
- route:
  - destination:

    weight: 25
  - destination:
      host: reviews.prod.svc.cluster.local
      subset: v1
    weight: 75

```

And the associated DestinationRule

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

name: reviews-destination

spec: 

host: reviews.prod.svc.cluster.local
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

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

name: reviews-route-two-domains

spec: 

hosts:
- reviews.com
http:
- route:
  - destination:
      host: dev.reviews.com
    weight: 25
  - destination:
      host: reviews.com
    weight: 75

```

	// One or more labels that indicate a specific set of pods/VMs whose
	// proxies should be configured to use these additional filters.  The
	// scope of label search is platform dependent. On Kubernetes, for

}

`EnvoyFilter` describes Envoy proxy-specific filters that can be used to customize the Envoy proxy configuration generated by Istio networking subsystem (Pilot). This feature must be used with care, as incorrect configurations could potentially destabilize the entire mesh.

NOTE 1: Since this is break glass configuration, there will not be any backward compatibility across different Istio releases. In other words, this configuration is subject to change based on internal implementation of Istio networking subsystem.

NOTE 2: There can be only one EnvoyFilter bound to a specific workload. The behavior is undefined if multiple EnvoyFilter configurations are specified for the same workload.

The following example for Kubernetes enables Envoy's Lua filter for all inbound calls arriving at service port 8080 of the reviews service pod with labels "app: reviews".

```yaml apiVersion: networking.istio.io/v1alpha3 kind: EnvoyFilter metadata: 

name: reviews-lua

spec: 

workloadLabels:
  app: reviews
filters:
- listenerMatch:
    portNumber: 8080
    listenerType: SIDECAR_INBOUND #will match with the inbound listener for reviews:8080
  filterName: envoy.lua
  filterType: HTTP
  filterConfig:
    inlineCode: |
      ... lua code ...

type Gateway 

type Gateway struct {

`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.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: Gateway metadata: 

name: my-gateway

spec: 

selector:
  app: my-gatweway-controller
servers:
- port:
    number: 80
    name: http
    protocol: HTTP
  hosts:
  - uk.bookinfo.com
  - eu.bookinfo.com
  tls:
    httpsRedirect: true # sends 301 redirect for http requests
- port:
    number: 443
    name: https
    protocol: HTTPS
  hosts:
  - uk.bookinfo.com
  - eu.bookinfo.com
  tls:
    mode: SIMPLE #enables HTTPS on this port
    serverCertificate: /etc/certs/servercert.pem
    privateKey: /etc/certs/privatekey.pem
- port:
    number: 9080
    name: http-wildcard
    protocol: HTTP
  hosts:
  - "*"
- port:
    number: 2379 # to expose internal service via external port 2379
    name: mongo
    protocol: MONGO
  hosts:
  - "*"

``` 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 "reviews.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).

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

name: bookinfo-rule

spec: 

hosts:
- reviews.prod.svc.cluster.local
- uk.bookinfo.com
- eu.bookinfo.com
gateways:
- my-gateway
- mesh # applies to all the sidecars in the mesh
http:
- match:
  - headers:
      cookie:
        user: dev-123
  route:
  - destination:
      port:
        number: 7777
      host: reviews.qa.svc.cluster.local
- match:
    uri:
      prefix: /reviews/
  route:
  - destination:
      port:
        number: 9080 # can be omitted if its the only port for reviews
      host: reviews.prod.svc.cluster.local
    weight: 80
  - destination:
      host: 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`.

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

name: bookinfo-Mongo

spec: 

hosts:
- mongosvr.prod.svc.cluster.local #name of internal Mongo service
gateways:
- my-gateway
tcp:
- match:
  - port: 27017
    sourceSubnet: "172.17.16.0/24"
  route:
  - destination:
      host: mongo.prod.svc.cluster.local
      port:
        number: 5555

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.

Abort specification is used to prematurely abort a request with a pre-specified error code. The following example will return an HTTP 400 error code for 10% of the requests to the "ratings" service "v1".

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

name: ratings-route

spec: 

hosts:

http:

      subset: v1
  fault:
    abort:
      percent: 10
      httpStatus: 400

```

The _httpStatus_ field is used to indicate the HTTP status code to return to the caller. The optional _percent_ field, a value between 0 and 100, is used to only abort a certain percentage of requests. If not specified, all requests are aborted.

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

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

name: reviews-route

spec: 

hosts:
- reviews.prod.svc.cluster.local
http:
- match:
  - sourceLabels:
      env: prod
  route:
  - destination:
      host: reviews.prod.svc.cluster.local
      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.

	Gateways []string `protobuf:"bytes,8,rep,name=gateways" json:"gateways,omitempty"`
}

HttpMatchRequest specifies a set of criterion to be met in order for the rule to be applied to the HTTP request. For example, the following restricts the rule to match only requests where the URL path starts with /ratings/v2/ and the request contains a `cookie` with value `user=jason`.

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

name: ratings-route

spec: 

hosts:
- ratings.prod.svc.cluster.local
http:
- match:
  - headers:
      cookie:
        regex: "^(.*?;)?(user=jason)(;.*)?"
    uri:
      prefix: "/ratings/v2/"
  route:
  - destination:
      host: ratings.prod.svc.cluster.local

```

type HTTPRedirect 

type HTTPRedirect struct {
	// On a redirect, overwrite the Path portion of the URL with this
	// value. Note that the entire path will be replaced, irrespective of the
	// request URI being matched as an exact path or prefix.
	Uri string `protobuf:"bytes,1,opt,name=uri,proto3" json:"uri,omitempty"`
	// On a redirect, overwrite the Authority/Host portion of the URL with
	// this value.
	Authority string `protobuf:"bytes,2,opt,name=authority,proto3" json:"authority,omitempty"`
}

HTTPRedirect can be used to send a 301 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.

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

name: ratings-route

spec:

	PerTryTimeout *google_protobuf.Duration `protobuf:"bytes,2,opt,name=per_try_timeout,json=perTryTimeout" json:"per_try_timeout,omitempty"`
}

Describes the retry policy to use when a HTTP request fails. For example, the following rule sets the maximum number of retries to 3 when calling ratings:v1 service, with a 2s timeout per retry attempt.

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

	// rewrite the Authority/Host header with this value.
	Authority string `protobuf:"bytes,2,opt,name=authority,proto3" json:"authority,omitempty"`
}

HTTPRewrite can be used to rewrite specific parts of a HTTP request before forwarding the request to the destination. Rewrite primitive can be used only with the DestinationWeights. The following example demonstrates how to rewrite the URL prefix for api call (/ratings) to ratings service before making the actual API call.

```yaml 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.

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

name: bookinfo-ratings

spec: 

host: ratings.prod.svc.cluster.local
trafficPolicy:
  loadBalancer:
    simple: ROUND_ROBIN

```

The following example sets up sticky sessions for the ratings service hashing-based load balancer for the same ratings service using the the User cookie as the hash key.

```yaml 

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

Consistent Hash-based load balancing can be used to provide soft session affinity based on HTTP headers, cookies or other properties. This load balancing policy is applicable only for HTTP connections. The affinity to a particular destination host will be lost when one or more hosts are added/removed from the destination service.

}

A Circuit breaker implementation that tracks the status of each individual host in the upstream service. Applicable to both HTTP and TCP services. For HTTP services, hosts that continually return 5xx errors for API calls are ejected from the pool for a pre-defined period of time. For TCP services, connection timeouts or connection failures to a given host counts as an error when measuring the consecutive errors metric. 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.

selector:
  app: my-ingress-gateway
servers:
- port:
    number: 80

}

`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.

```yaml 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

```yaml 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 uses a combination of service entry and TLS routing in virtual service to demonstrate the use of SNI routing to forward unterminated TLS traffic from the application to external services via the sidecar. The sidecar inspects the SNI value in the ClientHello message to route to the appropriate external service.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: ServiceEntry metadata: 

name: external-svc-https

spec: 

hosts:
- api.dropboxapi.com
- www.googleapis.com
- api.facebook.com
location: MESH_EXTERNAL
ports:
- number: 443
  name: https
  protocol: HTTPS
resolution: DNS

```

And the associated VirtualService to route based on the SNI value.

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

name: tls-routing

spec: 

hosts:
- api.dropboxapi.com

The following example demonstrates the use of a dedicated egress gateway through which all external service traffic is forwarded.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: ServiceEntry metadata: 

name: external-svc-httpbin

spec: 

hosts:
- httpbin.com
location: MESH_EXTERNAL
ports:
- number: 80
  name: http
  protocol: HTTP
resolution: DNS

```

Define a gateway to handle all egress traffic.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: Gateway metadata: 

name: istio-egressgateway

spec: 

selector:
  istio: egressgateway
servers:
- port:
    number: 80
    name: http
    protocol: HTTP
  hosts:
  - "*"

```

And the associated VirtualService to route from the sidecar to the gateway service (istio-egressgateway.istio-system.svc.cluster.local), as well as route from the gateway to the external service.

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

name: gateway-routing

spec: 

hosts:
- httpbin.com
gateways:
- mesh
- istio-egressgateway
http:
- match:
  - port: 80
    gateways:
    - mesh
  route:
  - destination:
      host: istio-egressgateway.istio-system.svc.cluster.local
- match:
  - port: 80
    gateway:
    - istio-egressgateway
  route:
  - destination:
      host: httpbin.com

```

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`.

```yaml 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

```

The following example demonstrates a service that is available via a Unix Domain Socket on the host of the client. The resolution must be set to STATIC to use unix address endpoints.

```yaml apiVersion: networking.istio.io/v1alpha3 kind: ServiceEntry metadata: 

name: unix-domain-socket-example

spec: 

hosts:
- "example.unix.local"
location: MESH_EXTERNAL
ports:
- number: 80
  name: http
  protocol: HTTP
resolution: STATIC
endpoints:
- address: unix:///var/run/example/socket

```

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:8080, uk.foo.bar.com:9080, and in.foo.bar.com:7080

```yaml apiVersion: networking.istio.io/v1alpha3 kind: ServiceEntry metadata: 

name: external-svc-dns

spec: 

hosts:
- foo.bar.com
location: MESH_EXTERNAL
ports:
- number: 80
  name: https
  protocol: HTTP
resolution: DNS
endpoints:
- address: us.foo.bar.com
  ports:
    https: 8080
- address: uk.foo.bar.com
  ports:
    https: 9080
- address: in.foo.bar.com
  ports:
    https: 7080

```

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

The application may still have to use DNS to resolve the service to an IP so that the outbound traffic can be captured by the Proxy. Alternatively, for HTTP services, the application could directly communicate with the proxy (e.g., by setting HTTP_PROXY) to talk to these services. 

const (
	// Assume that incoming connections have already been resolved (to a
	// specific destination IP address). Such connections are typically

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(#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).

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

SSL/TLS related settings for upstream connections. See Envoy's [TLS context](https://www.envoyproxy.io/docs/envoy/latest/api-v1/cluster_manager/cluster_ssl.html#config-cluster-manager-cluster-ssl) for more details. These settings are common to both HTTP and TCP upstreams.

    clientCertificate: /etc/certs/myclientcert.pem
    privateKey: /etc/certs/client_private_key.pem
    caCertificates: /etc/certs/rootcacerts.pem

type VirtualService 

type VirtualService struct {
	// REQUIRED. The destination hosts to which traffic is being sent. Could

	// platform, short-names can also be used instead of a FQDN (i.e. has no

	// 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

	// 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

	// 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

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".

```yaml 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`.

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

name: reviews-destination

spec: 

host: reviews.prod.svc.cluster.local
subsets:
- name: v1
  labels:
    version: v1
- name: v2
  labels:
    version: v2

```
