Setting up RabbitMQ Communication in a KinD Cluster

Welcome to our DevOps project focused on establishing RabbitMQ communication between applications using Kubernetes in Docker (KinD) and Helm charts!

Project Overview

This project aims to automate the setup process for establishing communication between applications using RabbitMQ as a message broker. It includes applications developed in Go, Helm charts for deployment on Kubernetes, and scripts for environment setup.

Tasks

Set up a local Kubernetes cluster using KinD. Deploy RabbitMQ to the Kubernetes cluster using Helm charts. Develop and deploy a producer application that publishes messages to RabbitMQ. Develop and deploy a consumer application that consumes messages from RabbitMQ. Ensure that all deployments are done securely without exposing any sensitive information.

Technologies Used

Kubernetes Docker KinD (Kubernetes in Docker) Helm RabbitMQ Go, Shell

Directory Structure

• apps: Contains applications developed in Go for producing and consuming messages.
  • consumer: Application for consuming messages from RabbitMQ.
  • producer: Application for producing messages to RabbitMQ.
• charts: Contains Helm charts for deploying applications to Kubernetes.
  • consumer-chart: Helm chart for deploying the Consumer application.
  • producer-chart: Helm chart for deploying the Producer application.
• scripts: Contains shell scripts for setting up the development environment and installing dependencies.
  • setup-environment.sh: Script for setting up the environment on an Ubuntu machine.
  • setup-environment2.sh: Alternate script for environment setup.

Usage

1. Clone this repository to your local machine:

   git clone https://github.com/DYagmur/DevOps.git
   

2. Navigate the script directory and Run the setup-environment.sh and setup-environment2.sh

3. Once Kind is installed, we can proceed to create a Kubernetes cluster named rabbitmq.

   sudo kind create cluster — name rabbitmq
   
   sudo docker ps
   
   Note that Kind will automatically set context to the created cluster and add a prefix `kind` in front of our cluster name. Hence, our cluster name will be kind-rabbitmq.
   

4. Check your context with this command:

   kubectl config get-contexts
   

5. Deploying rabbit mq with helm charts.

6. Add RabbitMQ Helm repository helm repo add bitnami https://charts.bitnami.com/bitnami

    helm repo update
   

7. Install RabbitMQ Chart Bitnami package for RabbitMQ

   helm install my-release oci://registry-1.docker.io/bitnamicharts/rabbitmq
   

8. Check this out repo. https://github.com/bitnami/charts/tree/main/bitnami/rabbitmq

9. Please check the pods health

   kubectl get pods
   

10. Open 2 different terminal and run the first terminal producer.go and run the second terminal consumer.go you will see the output which is communicated between each other.

11. Please use the this command to access RabbitMQ Management UI.

    kubectl port-forward --namespace default svc/my-release-rabbitmq 15672:15672
    

12. You can access the user and password below command if you don't add custom value.yaml file.

    echo "Username      : user"
    echo "Password      : $(kubectl get secret --namespace default my-rabbitmq -o jsonpath="{.data.rabbitmq-password}" | base64 -d)"
    echo "ErLang Cookie : $(kubectl get secret --namespace default my-rabbitmq -o jsonpath="{.data.rabbitmq-erlang-cookie}" | base64 -d)"
