Connexion with benefits for microservices

Connexion with benefits for microservices.

Connexion Plus

If you want to use Connexion for your microservice, you have to add an opentracing or prometheus client on your own. With this library, you instantiate everything before your connexion app starts and this library will take care to put it all together, so you get everything fine.

Importing

import connexion_plus

OpenTracing

Currently it is only supported the opentracing implementation of jaeger-client. If you want to use it, you have to initialize the client before you start your connexion app and give it via the tracer-parameter to the connexion_plus Factory, where the magic happens.

import connexion_plus
from jaeger_client import Config as jConfig

config = jConfig(
        config={
            'logging': True,
        },
    )
jaeger_tracer = config.initialize_tracer()

app = connexion.App(__name__)
connexion_plus.Factory(app, tracer=jaeger_tracer)

Prometheus

Currently, it is only the prometheus-flask-exporter supported for connexion, so only for flask connexion. You only have to set the metrics-parameter to True

import connexion_plus

app = connexion.App(__name__)
connexion_plus.Factory(app, metrics=True)

Example

If you want to use tracer and metrics together, see here a complete example.

import connexion_plus
from jaeger_client import Config as jConfig

config = jConfig(
        config={
            'logging': True,
        },
    )
jaeger_tracer = config.initialize_tracer()

app = connexion.App(__name__)
connexion_plus.Factory(app, tracer=jaeger_tracer, metrics=True)
