Evaluating AMQ Streams on OpenShift

Red Hat AMQ 7.5

For use with AMQ Streams 1.3 on OpenShift Container Platform


This guide describes how to install and manage AMQ Streams to evaluate its potential use in a production environment.

Chapter 1. Overview of AMQ Streams

AMQ Streams is based on Apache Kafka, a popular platform for streaming data delivery and processing. AMQ Streams makes it easy to run Apache Kafka on OpenShift.

AMQ Streams provides three operators:

Cluster Operator
Responsible for deploying and managing Apache Kafka clusters within an OpenShift cluster.
Topic Operator
Responsible for managing Kafka topics within a Kafka cluster running within an OpenShift cluster.
User Operator
Responsible for managing Kafka users within a Kafka cluster running within an OpenShift cluster.

The Cluster Operator can deploy the Topic Operator and User Operator (as part of an Entity Operator configuration) at the same time as a Kafka cluster.

Operators within the AMQ Streams architecture


1.1. Kafka Key Features

  • Designed for horizontal scalability
  • Message ordering guarantee at the partition level
  • Message rewind/replay

    • "Long term" storage allows the reconstruction of an application state by replaying the messages
    • Combines with compacted topics to use Kafka as a key-value store

1.2. Document Conventions


In this document, replaceable text is styled in monospace and italics.

For example, in the following code, you will want to replace my-namespace with the name of your namespace:

sed -i 's/namespace: .*/namespace: my-namespace/' install/cluster-operator/*RoleBinding*.yaml

Chapter 2. Try AMQ Streams

Install AMQ Streams and start sending and receiving messages from a topic in minutes.

You will:

  • Install AMQ Streams
  • Create a Kafka cluster
  • Access the Kafka cluster to send and receive messages

Ensure you have the prerequisites and then follow the tasks in the order provided in this chapter.

2.1. Prerequisites

  • OpenShift Container Platform cluster (3.11 and later) running on which to deploy AMQ Streams

2.2. Downloading AMQ Streams

Download a zip file that contains the resources required for installation along with examples for configuration.



  1. Download the amq-streams-x.y.z-ocp-install-examples.zip file from the AMQ Streams download site.
  2. Unzip the file to any destination.

    • On Windows or Mac, you can extract the contents of the ZIP archive by double clicking on the ZIP file.
    • On Red Hat Enterprise Linux, open a terminal window in the target machine and navigate to where the ZIP file was downloaded.

      Extract the ZIP file by executing the following command:

      unzip amq-streams-x.y.z-ocp-install-examples.zip

2.3. Installing AMQ Streams

Install AMQ Streams with the Custom Resource Definitions (CRDs) required for deployment.

In this task you create namespaces in the cluster for your deployment. It is good practice to use namespaces to separate functions.


  • Installation requires a user with cluster-admin role, such as system:admin


  1. Login in to the OpenShift cluster with cluster admin privileges.

    For example:

    oc login -u system:admin
  2. Create a new kafka (project) namespace for the AMQ Streams Kafka Cluster Operator.

    oc new-project kafka
  3. Modify the installation files to reference the new kafka namespace where you will install the AMQ Streams Kafka Cluster Operator.


    By default, the files work in the myproject namespace.

    • On Linux, use:

      sed -i 's/namespace: .*/namespace: kafka/' install/cluster-operator/*RoleBinding*.yaml
    • On Mac, use:

      sed -i '' 's/namespace: .*/namespace: kafka/' install/cluster-operator/*RoleBinding*.yaml
  4. Deploy the CRDs and role-based access control (RBAC) resources to manage the CRDs.

    oc new-project kafka
    oc apply -f install/cluster-operator/
  5. Create a new my-kafka-project namespace where you will deploy your Kafka cluster.

    oc new-project my-kafka-project
  6. Give access to my-kafka-project to a non-admin user developer.

    For example:

    oc adm policy add-role-to-user admin developer -n my-kafka-project
  7. Give permission to the Cluster Operator to watch the my-kafka-project namespace.

    oc set env deploy/strimzi-cluster-operator STRIMZI_NAMESPACE=kafka,my-kafka-project -n kafka
    oc apply -f install/cluster-operator/020-RoleBinding-strimzi-cluster-operator.yaml -n my-kafka-project
    oc apply -f install/cluster-operator/032-RoleBinding-strimzi-cluster-operator-topic-operator-delegation.yaml -n my-kafka-project
    oc apply -f install/cluster-operator/031-RoleBinding-strimzi-cluster-operator-entity-operator-delegation.yaml -n my-kafka-project

    The commands create role bindings that grant permission for the Cluster Operator to access the Kafka cluster.

  8. Create a new cluster role strimzi-admin.

    oc apply -f install/strimzi-admin
  9. Add the role to the non-admin user developer.

    oc adm policy add-cluster-role-to-user strimzi-admin developer

2.4. Creating a cluster

Create a Kafka cluster, then a topic within the cluster.

When you create a cluster, the Cluster Operator you deployed watches for new Kafka resources.


  • For the Kafka cluster, a Cluster Operator is deployed
  • For the topic, a running Kafka cluster


  1. Log in to the my-kafka-project namespace as user developer.

    For example:

    oc login -u developer
    oc project my-kafka-project

    After new users log in to OpenShift Container Platform, an account is created for that user.

  2. Create a new my-cluster Kafka cluster with 3 Zookeeper and 3 broker nodes.

    • Use ephemeral storage
    • Expose the Kafka cluster outside of the OpenShift cluster using an external listener configured to use route.

      cat << EOF | oc create -f -
      apiVersion: kafka.strimzi.io/v1beta1
      kind: Kafka
        name: my-cluster
          replicas: 3
            plain: {}
            tls: {}
              type: route
            type: ephemeral
          replicas: 3
            type: ephemeral
          topicOperator: {}
  3. Wait for the cluster to be deployed:

    oc wait kafka/my-cluster --for=condition=Ready --timeout=300s -n kafka
  4. Now that your cluster is running, create a topic to publish and subscribe from your external client.

    Create the following my-topic custom resource definition with 3 replicas and 3 partitions in the my-cluster Kafka cluster:

    cat << EOF | oc create -f -
    apiVersion: kafka.strimzi.io/v1beta1
    kind: KafkaTopic
      name: my-topic
        strimzi.io/cluster: "my-cluster"
      partitions: 3
      replicas: 3

2.5. Accessing the cluster

As route is used for external access to the cluster, a cluster CA certificate is required to enable TLS (Transport Layer Security) encryption between the broker and the client.


  • A Kafka cluster running within the OpenShift cluster
  • A running Cluster Operator


  1. Find the address of the bootstrap route:

    oc get routes my-cluster-kafka-bootstrap -o=jsonpath='{.status.ingress[0].host}{"\n"}'

    Use the address together with port 443 in your Kafka client as the bootstrap address.

  2. Extract the public certificate of the broker certification authority:

    oc extract secret/my-cluster-cluster-ca-cert --keys=ca.crt --to=- > ca.crt
  3. Import the trusted certificate to a truststore:

    keytool -keystore client.truststore.jks -alias CARoot -import -file ca.crt

    You are now ready to start sending and receiving messages.

2.6. Sending and receiving messages from a topic

Test your AMQ Streams installation by sending and receiving messages outside the cluster from my-topic.

Use a terminal to run a Kafka producer and consumer on a local machine.



  1. Download the latest version of the AMQ Streams archive (amq-streams-x.y.z-bin.zip) from the AMQ Streams download site.

    Unzip the file to any destination.

  2. Open a terminal and start the Kafka console producer with the topic my-topic and the authentication properties for TLS:

    bin/kafka-console-producer.sh --broker-list <route-address>:443 --producer-property security.protocol=SSL --producer-property ssl.truststore.password=password --producer-property ssl.truststore.location=./client.truststore.jks --topic my-topic
  3. Type your message into the console where the producer is running.
  4. Press Enter to send the message.
  5. Open a new terminal tab or window and start the Kafka console consumer to receive the messages:

    bin/kafka-console-consumer.sh --bootstrap-server <route-address>:443 --consumer-property security.protocol=SSL --consumer-property ssl.truststore.password=password --consumer-property ssl.truststore.location=./client.truststore.jks --topic my-topic --from-beginning
  6. Confirm that you see the incoming messages in the consumer console.
  7. Press Crtl+C to exit the Kafka console producer and consumer.
