example

The following example will show off the usage of patron involving all components implemented. The processing will be kicked of by sending a request to the HTTP component. The flow then will be the following:

• HTTP -> RabbitMQ publish
• RabbitMQ consumer -> kafka publish
• Kafka consumer -> log to stdout

Since tracing instrumentation is in place we can observer the flow in jaeger.

Prerequisites

• Docker
• Docker compose

setting up environment

To run the full example we need to start jaeger and prometheus. We can startup both of them using docker-compose with the following command.

docker-compose up -d

To tear down the above just:

docker-compose down

running the example

just run (within the examples folder):

go run main.go

and the use curl to send a request:

curl -i -H "Content-Type: application/json" -X POST http://localhost:50000

After that head over to jaeger and prometheus.
