RabbitMQ Messaging Topology Operator Overview

Secure your stack with a hardened RabbitMQ Messaging Topology Operator image freshly-built by Minimus. Minimus images always include the most up-to-date package version for all packages and dependencies contained in the image.

RabbitMQ Messaging Topology Operator is a Kubernetes operator that lets developers create and manage RabbitMQ messaging topologies within a RabbitMQ cluster using a declarative Kubernetes API. It works alongside the RabbitMQ Cluster Operator.

Try It Out

Prerequisites

A running Kubernetes cluster
RabbitMQ Cluster Operator installed in the cluster
A RabbitMQ cluster deployed using the Cluster Operator
cert-manager v1.2.0 or above installed in the cluster
kubectl installed and configured
Helm v3.8 or higher for OCI support (Installation instructions)

Step 1: Start Cluster

If you have a cluster to work with, skip this step. Otherwise, start a Minikube cluster. Deployment instructions

Step 2: Create a Namespace

Create a namespace for the operator:

kubectl create namespace rabbitmq-system

Step 3: Prepare the Manifest

Download the operator manifest:

curl -sL https://github.com/rabbitmq/messaging-topology-operator/releases/latest/download/messaging-topology-operator-with-certmanager.yaml \
  -o messaging-topology-operator.yaml

Next, we need to edit the file messaging-topology-operator.yaml to point to the Minimus registry:

      containers:
        - image: reg.mini.dev/rmq-messaging-topology-operator:latest

If you have yq installed, you can run the following command to make the change:

yq -i '
  select(.kind == "Deployment" and .metadata.name == "messaging-topology-operator") 
  |= .spec.template.spec.containers[0].image = "reg.mini.dev/rmq-messaging-topology-operator:latest"
' messaging-topology-operator.yaml

Step 4: Install the RabbitMQ Messaging Topology Operator

Apply the manifest:

kubectl apply -f messaging-topology-operator.yaml

Wait a minute and check that the operator Pod is up and running:

kubectl -n rabbitmq-system get po

The operator Pod should be listed and running, for example:

NAME                                                   READY   STATUS    RESTARTS   AGE
messaging-topology-operator-7d4b6f8c9f-x2k4n           1/1     Running   0          1m

Verify that the expected Minimus image is in use:

kubectl -n rabbitmq-system describe deploy messaging-topology-operator | grep Image:

It should return:

Image:           reg.mini.dev/rmq-messaging-topology-operator:latest

Step 5: Create a Messaging Topology Resource

With the operator running, you can declaratively manage RabbitMQ resources such as queues, exchanges, bindings, users, vhosts, policies, permissions, federations, etc.

For example, create a queue by saving the following to test-queue.yaml. Add in you RabbitMQ cluster name:

apiVersion: rabbitmq.com/v1beta1
kind: Queue
metadata:
  name: test-queue
spec:
  name: test-queue
  rabbitmqClusterReference:
    name: <your-rabbitmq-cluster-name>

Apply it:

kubectl apply -f test-queue.yaml

Check the queue status:

kubectl get queues

For more examples, see the upstream examples and the usage guide.

Technical Considerations

The RabbitMQ Messaging Topology Operator image provided by Minimus is a slim, security-hardened alternative to the public image. The images are largely interchangeable, with a few differences as noted below.

RabbitMQ Messaging Topology Operator built by Minimus:

Runs as non-root by default for a security-first approach that protects against privilege escalation attacks.
Drill down on the version specification tab to see the default user, listening ports, entrypoint, volumes, environment variables, etc.

The Payoff

A hardened, minimal image that will remain more secure for the long run and accrue vulnerabilities at a slower rate.

See the risk reduction dashboard for a detailed CVE comparison over the past 30 days.
Review the compliance report to see the default hardening and security configurations for the image.
