Hands-On High Performance with Go

RabbitMQ

RabbitMQ is a popular open source message broker written in Erlang. It uses a protocol called the Advanced Message Queueing Protocol (AMQP) in order to pass messages through its queueing system. Without further ado, let's set up a RabbitMQ instance and pass messages to and from it using Go:

1. First, we need to start up a RabbitMQ instance using Docker:

docker run -d --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:3-management

2. Then, we have a RabbitMQ instance, complete with the management portal, running on our host.
3. Now, we can use the Go AMQP library (https://github.com/streadway/amqp) in order to pass messages to and from our RabbitMQ system with Go.

We will start by creating a listener. Let's see this procedure step by ...
