|

|
||||
// `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). In addition, the
|
||||
// endpoints of a service entry can also be dynamically selected by
|
||||
// using the `workloadSelector` field. These endpoints can be VM
|
||||
// workloads declared using the `WorkloadEntry` object or Kubernetes
|
||||
// pods. The ability to select both pods and VMs under a single
|
||||
// service allows for migration of services from VMs to Kubernetes
|
||||
// without having to change the existing DNS names associated with the
|
||||
// services.
|
||||
//
|
||||
// The following example declares a few external APIs accessed by internal
|
||||
// applications over HTTPS. The sidecar inspects the SNI value in the
|
||||
// ClientHello message to route to the appropriate external service.
