Microanut service registration for consul client will resutle in a failure even if the service is registered about micronaut-discovery-client HOT 8 CLOSED

do you have a sample application?

from micronaut-discovery-client.

I do, but I'm trying to make it a separate project so it's not dependent on a lot of cruft.

The main idea is that the registration part works per the #517 instructions but if I try a consul client, it does not work. Give me about an hour, I think I can give you an example. But everything I've tried so far to make a consul client work has resulted in a different exception.

Right now I'm just following the grpc demo tutorial to re-create the example. Since it'll need to have a running consul application and a test dependent on a running consul, it'll take me a second.

consul client failure

This one isn't giving the same error. I'm trying to recreate from scratch. I think I followed the direcitons right on here.

The test goes as follows:

1. Creates grpc server on a random port, registers successfully with consul
2. test attempts doesn't communicate with consul for client discovery (see Clients.java) -

The client returns, but when executing it's not using the client consul discovery.

So I'm testing with the latest SNAPSHOT version - and still not able to get a consul client. Maybe I have a missing dependency. Is there any sample project that exists that successfully grabs a consul client? No matter what I try, it doesn't work. So I'm not sure if I just set it up wrong or what to do.

I tested with the latest SNAPSHOT version and the service registration works with the original dependencies. Now when I try to send a payload, it looks like it expects SSL to be turned on:

I'm assuming this is now a confugiration issue. Are there instructions to setup SSL or disable it?

from micronaut-discovery-client.

OK - validated and got it to work on the latest snapshot. Works as it is designed! Thanks!

from micronaut-discovery-client.

can you try with Micronaut Framework 4.1.4? Does it work for you without pinning any snapshots?

from micronaut-discovery-client.

Tried it. Still works. Is there a way I can programatically get the client? I see that we put the channel name in the annotation - is there a way to create the same bean without the annotation?

So instead of this:

    @Singleton
    @Bean
    @Named("vectorizer")
    PipeServiceGrpc.PipeServiceStub vectorizorPipeServiceStub(
            @GrpcChannel("vectorizer") ManagedChannel channel) {
        return PipeServiceGrpc.newStub(channel);
    }

Is there something like:

@Inject
GreeterGrpcStub buildStub(ConsulManagedGrpcClientFactory cf, String serviceaName) {
      ManagedChannel grpc = cf.getServiceChannel(serviceName);
      return GreeterGrpc.newStub(
                grpc);
}

Of course, I know there's no ConsulManagedGrpcClientFactory, but I could really find one handy to use.

I have multiple versions of the same service that I would run in the same JVM. I would like to have the service names in the configuration and dynamically create the clients at anytime. I figured since the annotation does inject the channel, there might be a way to accomplish the getting a managed channel from Consul but by only passing in the service name? Can you nudge me in the right direction to accomplish this?
