Installation

Setup RabbitMQ

Start RabbitMQ in docker container in a separate terminal: docker-compose up -d.

Connect to the container:

docker exec -it broadway_demo_rabbitmq_1 /bin/bash

and add the test user:

rabbitmqctl add_user test test
rabbitmqctl set_user_tags test administrator
rabbitmqctl set_permissions -p / test ".*" ".*" ".*"

Then disconnect from the rabbit container using Ctrl+d.

Queue

Based on this tutorial.

Create a queue named my_queue. Get the dependencies mix deps.get. Start an Elixir shell iex -S mix.

Connect to the RabbitMQ and create a queue named my_queue:

options = [
  host: "localhost",
  port: 5672,
  username: "test",
  password: "test"
]
{:ok, connection} = AMQP.Connection.open(options)
{:ok, channel} = AMQP.Channel.open(connection)

case AMQP.Queue.declare(channel, "my_queue", durable: true) do
  :ok -> :ok
  {:ok, info} -> :ok
end

Press Ctrl+c twice to exit the Elixir shell.

Connect to the container and check if the queue was created:

docker exec -it broadway_demo_rabbitmq_1 /bin/bash

rabbitmqctl list_queues

should result in something like this:

I have no name!@ecfb76f11fdf:/$ rabbitmqctl list_queues
Timeout: 60.0 seconds ...
Listing queues for vhost / ...
name	messages
my_queue	0
