[Ruby] How to use Grpc::Health::Checker?

[Michel Vocks]

Hello folks,

I would like to use the ruby Health-Check implementation. I was able to find the following documentation: https://www.rubydoc.info/gems/grpc/Grpc/Health/Checker

Anyway, if I want to implement that service I get the error "Error occured: uninitialized constant Grpc".

I'm using the following code snippet:

 # Implement health service.
 health_svc = Grpc::Health::Checker.new
 health_svc.add_status("myservice", GRPC::Core::StatusCodes::SERVING)

I'm also unsure how to attach that service to my gRPC server?

Is there somewhere an official example available?

Any help is much appreciated! :-)

I was able to solve it with the following code snippet:

require 'grpc/health/checker'

# Implement health service.
health_svc = Grpc::Health::Checker.new

health_svc.add_status("plugin", Grpc::Health::V1::HealthCheckResponse::ServingStatus::SERVING)

# Register gRPC server and handle.
host = '127.0.0.1'
s = GRPC::RpcServer.new
port = s.add_http2_port(host+':0', :this_port_is_insecure)
s.handle(health_svc)
