# Envoy XDS Types
This package provides the Go types for the Envoy XDS APIs.
## Creating an XDS API Cluster REST Discovery Response
To create a CDS response, use the `cluster.NewResponse` func.
```go
package main
import (
"encoding/json"
"log"
"github.com/jasonmccallister/envoy-xds-types/cluster"
)
func main() {
// create the cluster resources
resources := []cluster.Resource{
{
ResourceType: "type.googleapis.com/envoy.config.cluster.v3.Cluster",
Type: "LOGICAL_DNS",
Name: "cluster_name",
DNSLookupFamily: "V4_ONLY",
LoadAssignment: cluster.LoadAssignment{
ClusterName: "cluster_name",
Endpoints: []cluster.Endpoints{
{
LbEndpoints: cluster.LBEndpoints{
Endpoint: cluster.LBEndpoint{
HealthCheckConfig: &cluster.HealthCheckConfig{
Hostname: "example.com",
PortValue: 443,
},
Address: cluster.Address{
SocketAddress: cluster.SocketAddress{
Address: "example.com",
PortValue: 443,
},
},
},
},
},
},
},
TransportSocket: &cluster.TransportSocket{
Name: "envoy.transport_sockets.tls",
TypedConfig: cluster.TransportSocketTypedConfig{
Type: "type.googleapis.com/envoy.extensions.transport_sockets.tls.v3.UpstreamTlsContext",
SNI: "example.com",
},
},
},
}
// generate the cluster response with those resources
response := cluster.NewResponse("V3", cluster.ControlPlane{Identifier: "control-plane-id"}, resources)
// marshal the response to JSON
data, err := json.Marshal(response)
if err != nil {
log.Fatal("Error marshalling response: ", err)
}
// return the response
}
```
