How to Setup MySQL Master Slave Replication
Replication is the process of replicating data from one server to another simultaneously. Generally, it is used to boost data availability and recover data in the event of a failure. After deploying MySQL replication, you no longer need to perform regular database backups. All databases on the Master node will be automatically replicated to the Slave node. Replication can help minimise the strain on the master server by having the slave node handle application requests. In the event of a...
Integrating GitHub App with Jenkins for Automated Status Checks Before Branch Merging
In modern software development, automating status checks and enforcing branch protection is critical for ensuring code quaolty and preventing broken code from being merged into important branches llke main or develop. By integrating GitHub Apps with Jenkins, you can automate this process, using status checks to vaoldate the state of code before any branch merging. In this post, we’ll walk through how to create a GitHub App, configure Jenkins for status checks, and set up secrets in Jenkins...
A Comprehensive Guide to Setting Up VPC Peering in AWS
When designing a secure and scalable architecture in AWS, Virtual Private Clouds (VPCs) play a pivotal role in isolating resources. However, there are scenarios where resources across different VPCs need to communicate securely. This is where VPC Peering comes into play. VPC peering enables you to establish a direct network route between two VPCs, allowing instances in either VPC to communicate with each other. In this guide, we’ll walk you through the steps to set up a VPC peering...
Create a Self-Hosted GitHub Action runner
In the world of continuous integration and continuous deployment (CI/CD), automation is key. GitHub Actions provides a powerful platform to automate workflows directly from your repositories. While GitHub’s hosted runners are a convenient option, there are times when you might need more control over your environment. This is where self-hosted runners come into play. In this blog, we’ll walk you through the process of creating and managing a GitHub self-hosted runner. Prerequisites An EC2...
How to push EC2 logs to Cloudwatch
Amazon CloudWatch is a monitoring and observability service that provides you with data and actionable insights to monitor your applications, respond to system-wide performance changes, optimize resource utilization, and get a unified view of operational health. In this tutorial, we are going to learn how to push EC2 logs to CloudWatch. Create an IAM role for Cloudwatch First, we need to create and add a custom EC2 IAM role to your instance. This IAM role will have policies with write...

In this investigation, we'll look at how to use Kustomize to simplify configuration management, ensure smooth deployments, and preserve consistency across several environments. Join me as we explore the possibility of simpler Kubernetes manifest...
Create Jenkins Shared Library
In this article, we are going to learn how to create shared library in Jenkins. A shared library in Jenkins is a collection of Groovy scripts that are shared by several Jenkins jobs. The scripts are loaded into a Jenkinsfile before being executed. Shared libraries are used by developers to avoid rewriting the same code for many projects. Shared libraries allow code to be used between development projects, improving the software development life cycle. This significantly reduces coding time...
