Run RabbitMQ server in Docker

Question

I'm getting an EOFException when connecting to the vanilla RabbitMQ Docker container. The log directory is empty /var/log/rabbitmq contains no files. The web console works without problems. It's just connecting to it that doesn't work.

Since this is the vanilla container from the Docker Hub, I presume it's me omitting something basic. But what ? :-)

Is there something else I can check ?

---

The command to create the container:

sudo docker run -d --hostname konijn --name konijn -p 5672:5762 -p 5671:5671 -p 15672:15672 rabbitmq:3.6.6-management

It shows up as running:

$ sudo docker ps
CONTAINER ID        IMAGE                       COMMAND                  CREATED             STATUS              PORTS                                                                                                                NAMES
0a62c2635d17        rabbitmq:3.6.6-management   "docker-entrypoint.sh"   12 seconds ago      Up 10 seconds       4369/tcp, 5672/tcp, 0.0.0.0:5671->5671/tcp, 15671/tcp, 25672/tcp, 0.0.0.0:15672->15672/tcp, 0.0.0.0:5672->5762/tcp   konijn

When running this code sample:

  @Test
  public void testUnprotectedConnection() throws Exception {
    final ConnectionFactory factory = new ConnectionFactory();
    factory.setUri("amqp://guest:guest@localhost:5672/");
    Connection conn = factory.newConnection();
  }

I'm getting:

Answer 1

You are exposing 5672:5762 ports. Inner port of container is 5762, but RabbitMQ default port is 5672.
