singnet/example-service

Simple arithmetic service compatible with SingularityNET platform. Can be used as a starting point to build services on the platform

example-service's Issues

Logging typo?

In

example-service/run_example_service.py

Line 57 in 8025c70

log.info("Launching {} on port {}".format(str(registry[service_name]), service_module))

shouldn't it be instead

        log.info("Launching {} on port {}".format(service_module, str(registry[service_name])))

?

Recipient Address from service metadata does not Match what was retrieved from Channel.

@raamb
Was working on deploying the service to sent platform and most of the tutorials in this do not cover if we are deploying it from certain IP.

I tried to match the port on my service_metadata and port on my organization config but still having this problem.

Clarification - Decentralized Service Workers

So, if I have this right, you can create a service consumable by SingularityNET. A clean way is to use Docker containers but I'm guessing that isn't a 100% requirement. I'm still not entirely clear on this interaction but I do have a preliminary question: What about a decentralized service worker? Pyinstaller is a not-so-bad path to cross-platform. Shouldn't I be able to embed my service in my decentralized app?

I'm pretty sure I'll be able to but I just want to ask before-hand to make sure I'm not going to run into any problems along the way.

Thanks
