Overview
KubeDB is the Kubernetes Native Database Management Solution which simplifies and automates routine database tasks such as Provisioning, Monitoring, Upgrading, Patching, Scaling, Volume Expansion, Backup, Recovery, Failure detection, and Repair for various popular databases on private and public clouds. The databases supported by KubeDB include MongoDB, Elasticsearch, MySQL, MariaDB, Redis, PostgreSQL, FerretDB, SingleStore, Percona XtraDB, and Memcached. Additionally, KubeDB also supports ProxySQL, PgBouncer, Pgpool, ZooKeeper and the streaming platform Kafka, RabbitMQ. You can find the guides to all the supported databases in KubeDB . In this tutorial we will deploy RabbitMQ Cluster in Amazon Elastic Kubernetes Service (Amazon EKS). We will cover the following steps:
- Install KubeDB
- Deploy RabbitMQ Cluster
- Publish & Consume Messages with RabbitMQ
Get Cluster ID
We need the cluster ID to get the KubeDB License. To get cluster ID, we can run the following command:
$ kubectl get ns kube-system -o jsonpath='{.metadata.uid}'
8e336615-0dbb-4ae8-b72f-2e7ec34c399d
Get License
Go to Appscode License Server to get the license.txt file. For this tutorial we will use KubeDB.
Install KubeDB
We will use helm to install KubeDB. Please install helm
, if it is not already installed.
Now, let’s install KubeDB
.

Deploy RabbitMQ Cluster
We are going to Deploy RabbitMQ Cluster by using KubeDB. First, let’s create a Namespace in which we will deploy RabbitMQ.
$ kubectl create namespace demo
namespace/demo created
Here is the yaml of the RabbitMQ we are going to use:
apiVersion: kubedb.com/v1alpha2
kind: RabbitMQ
metadata:
name: rabbitmq-cluster
namespace: demo
spec:
version: "3.12.12"
replicas: 3
storage:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 1Gi
storageClassName: gp2
storageType: Durable
deletionPolicy: WipeOut
Let’s save this yaml configuration into rabbitmq-cluster.yaml
Then apply the above RabbitMQ yaml,
$ kubectl apply -f rabbitmq-cluster.yaml
rabbitmq.kubedb.com/rabbitmq-cluster created
In this yaml,
spec.replicas
is used to provide the number of required replicas or, peers for intended rabbitmq cluster.spec.version
field specifies the version of RabbitMQ. Here, we are using RabbitMQ3.12.12
. You can list the KubeDB supported versions of RabbitMQ by running$ kubectl get rabbitmqversions
command.spec.storage.storageClassName
is the name of the StorageClass used to provision PVCs.spec.deletionPolicy
field is Wipeout means it will be deleted without restrictions. It can also be “Halt”, “Delete” and “DoNotTerminate”.
Once these are handled correctly and the RabbitMQ object is deployed, you will see that the following resources are created:
$ kubectl get all -n demo
NAME READY STATUS RESTARTS AGE
pod/rabbitmq-cluster-0 1/1 Running 0 3m24s
pod/rabbitmq-cluster-1 1/1 Running 0 2m52s
pod/rabbitmq-cluster-2 1/1 Running 0 2m14s
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
service/rabbitmq-cluster ClusterIP 10.128.71.135 <none> 15672/TCP,5672/TCP 3m26s
service/rabbitmq-cluster-pods ClusterIP None <none> 4369/TCP,25672/TCP 3m26s
NAME TYPE VERSION AGE
appbinding.appcatalog.appscode.com/rabbitmq-cluster kubedb.com/rabbitmq 3.12.12 3m25s
Let’s check if the rabbitmq-cluster
is ready to use,
$ kubectl get rabbitmq -n demo rabbitmq-cluster
NAME TYPE VERSION STATUS AGE
rabbitmq-cluster kubedb.com/v1alpha2 3.12.12 Ready 3m50s
We have successfully deployed RabbitMQ in Amazon EKS. Now we can exec into the container to use the database.
Connect with RabbitMQ UI
We will use port forwarding to connect with RabbitMQ.
Port-forward the Service
KubeDB will create few Services to connect with the RabbitMQ. Let’s check the Services by following command,
$ kubectl get service -n demo
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
rabbitmq-cluster ClusterIP 10.128.71.135 <none> 15672/TCP,5672/TCP 4m26s
rabbitmq-cluster-pods ClusterIP None <none> 4369/TCP,25672/TCP 4m26s
Here, we are going to use rabbitmq-cluster
Service to connect with the database. Now, let’s port-forward the rabbitmq-cluster
Service to the port 9200
to local machine:
$ kubectl port-forward -n demo svc/rabbitmq-cluster 15672
Forwarding from 127.0.0.1:15672 -> 15672
Forwarding from [::1]:15672 -> 15672
Now, our RabbitMQ UI is accessible at localhost:15672
.
Accessing RabbitMQ Through UI
To access RabbitMQ through the UI, we first need the login credentials.
Get the Credentials
KubeDB create some Secrets for the database. Let’s check which Secrets have been created by KubeDB for our rabbitmq-cluster
.
$ kubectl get secret -n demo
NAME TYPE DATA AGE
rabbitmq-cluster-admin-cred kubernetes.io/basic-auth 2 4m57s
rabbitmq-cluster-config Opaque 2 4m57s
rabbitmq-cluster-erlang-cookie Opaque 1 4m57s
Now, we can use rabbitmq-cluster-admin-cred
which contains the admin level credentials to connect with the RabbitMQ. You can obtain these credentials by running the following commands:
$ kubectl get secret -n demo rabbitmq-cluster-admin-cred -o jsonpath='{.data.username}' | base64 -d
admin
$ kubectl get secret -n demo rabbitmq-cluster-admin-cred -o jsonpath='{.data.password}' | base64 -d
873Ft~Zjr99*6FKN
With the credentials in hand, open your web browser and navigate to http://localhost:15672/
. You will see the RabbitMQ login panel. Enter the username admin
and the password 873Ft~Zjr99*6FKN
to access the RabbitMQ UI.
Once logged in, click on the Queues & Streams
section to manage queues. Here, we are going to add a new queue named test-queue
.
After creating the queue, click on test-queue
to view its overview. This section provides various details and actions for managing the queue.
Next, navigate to the Publish message
section to publish some test messages to test-queue
. Enter the message details in the payload
field and click the Publish message
button to publish the message.
To retrieve the messages you have just published, go to the Get messages
section of test-queue
. Click the Get Message(s)
button, and the messages will be fetched from the queue.
You can repeat the process of publishing and getting messages to see how RabbitMQ handles them.
Finally, the statistics in the overview section of test-queue
will show the number of messages and other relevant information after your interactions.
So, we have deployed RabbitMQ on Kubernetes and accessed the RabbitMQ UI for publishing and consuming messages. More information about Deploy & Manage RabbitMQ on Kubernetes can be found in RabbitMQ Kubernetes .
We have made a in depth tutorial on Provision and Manage RabbitMQ Cluster on Kubernetes using KubeDB. You can have a look into the video below:
