GRPC xds example

Kubernetes environment:

• Kubernetes version v1.24.0 (Use Kind with private registry to create a local Kubernetes cluster and local registry for push and pull image faster)
• Monitoring operator: Kube prometheus stack
• Go version: go1.18.3

Configurations

You can configure grpc client and grpc xds client by change the command line arguments in deployment file

• --target (-t): uri of the target grpc server. It must begin with xds:/// prefix for xds client. Example: xds:///localhost:50051
• --concurrency (-c): Number of concurrent requests to run the client service. Example: 100
• --duration (-d): A duration to send requests to the server. Duration is a possibly signed sequence of decimal numbers. Valid time units are ns, us (or µs), ms, s, m, h.). Ex: 300ms, -1.5h or 2h45m.
