Using xDS gRPC
This page explains how to enable xDS gRPC usage in your Quarkus application.
| This Quarkus xDS gRPC integration currently doesn’t support building native executables due to the issues with shaded grpc-netty library while running native IT tests. |
Configuring your project
Edit the pom.xml file to add the Quarkus gRPC xDS dependency (just under <dependencies>):
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-grpc-xds</artifactId>
</dependency>
This transitively adds io.quarkus:quarkus-grpc extension dependency.

Server configuration
Configuration property fixed at build time - All other configuration properties are overridable at runtime
Type |
Default |
|
|---|---|---|
Explicitly enable use of XDS. Environment variable: |
boolean |
|
Use secure credentials. Environment variable: |
boolean |
|
Server configuration example
To enable server xDS, use the following configuration.
xDS must be explicitly enabled on the server, then verify you use it on the right xDS server port (default is 9000). If you want to use XdsServerCredentials set xds.secure to true.
quarkus.grpc.server.xds.enabled=true
#quarkus.grpc.server.xds.secure=true
quarkus.grpc.server.port=30051
When xDS is configured, plain-text is automatically disabled.

Client configuration
Configuration property fixed at build time - All other configuration properties are overridable at runtime
Type |
Default |
|
|---|---|---|
Explicitly enable use of XDS. Environment variable: |
boolean |
|
Use secure credentials. Environment variable: |
boolean |
|
Optional explicit target. Environment variable: |
string |
| When xDS target property is used, name resolver, host, and port are not used |
Client configuration example
To enable client xDS, use the following configuration.
You can either explicitly enable xDS or you use xds name resolver, and make sure you point it to the right xDS server port (default is 9000). If you want to use XdsChannelCredentials set xds.secure to true.
#quarkus.grpc.clients.<client-name>.xds.enabled=true
#quarkus.grpc.clients.<client-name>.xds.secure=true
quarkus.grpc.clients.<client-name>.name-resolver=xds
quarkus.grpc.clients.<client-name>.port=30051
When xDS is configured, plain-text is automatically disabled.

Kubernetes configuration example
Below is an example of (required) additional configuration when using xDS gRPC with the Istio Service Mesh in Kubernetes.
quarkus.kubernetes.ports.grpc.container-port=30051
quarkus.kubernetes.annotations."inject.istio.io/templates"=grpc-agent
quarkus.kubernetes.annotations."proxy.istio.io/config"={"holdApplicationUntilProxyStarts": true}
