Kubernetes Policy as Code with Kyverno - Enforcing Best Practices the Native Way
Managing security and compliance in Kubernetes clusters can be challenging, especially when dealing with multiple teams and environments. Manual policy enforcement is error-prone and doesn’t scale. This is where Kyverno comes in - a Kubernetes-native policy engine that helps you enforce best practices automatically using simple YAML policies. In this guide, we’ll walk through setting up Kyverno and implementing essential policies that every Kubernetes cluster should have. What is...
Installing MySQL Operator on Kubernetes
Managing MySQL databases in production Kubernetes environments can quickly become overwhelming. You’re dealing with persistent volumes, StatefulSets, secrets management, replication setup, and failover mechanisms—all while ensuring your data remains consistent and highly available. What if there was a way to automate all of this complexity with just a few commands?Enter the MySQL Operator for Kubernetes—a game-changing tool developed by Oracle that transforms complex database management into...
The Complete SBOM Guide for Real-World DevOps
In the age of increasing supply chain attacks and strict compliance requirements, knowing exactly what’s inside your container images is no longer optional. That’s where SBOM (Software Bill of Materials) comes in. An SBOM is a formal, machine-readable inventory of all software components (libraries, packages, binaries) included in a container image or application. With Docker now supporting SBOM generation natively from version v20.10.24, DevOps teams can integrate security and compliance...
Docker Security Hardening in Production
Running Docker containers in production environments requires a comprehensive security strategy that goes far beyond basic container deployment. While Docker provides convenience and portability, it also introduces unique security challenges that can expose your infrastructure to serious vulnerabilities if not properly addressed.In this comprehensive guide, we’ll explore enterprise-grade Docker security hardening techniques, covering everything from container isolation and image scanning to...
How to Run Docker Containers as Non-Root in Production
Running Docker containers as root inside the container may work during local development — but in production environments, it’s a serious security risk. In this advanced guide, we’ll walk through: Why root containers are dangerous in real-world systems How to properly design your Dockerfile to run as a non-root user Best practices used in enterprises How to enforce this in CI/CD pipelines and Kubernetes The Real Risk of Running Containers as RootWhen a container runs as root inside...
Debugging with Git bisects
Have you ever introduced a bug into your codebase and then spent hours, maybe even days, trying to figure out exactly when it happened? Scrolling through endless commits, comparing files, and feeling increasingly frustrated? If so, you’re not alone! Luckily, Git has a powerful tool that can significantly speed up this debugging process: git bisect. Think of it as a detective for your code, helping you pinpoint the exact commit that introduced a problem. This article will guide you through...
Backing Up Your Amazon EKS Cluster with Velero
Kubernetes has become the backbone of modern cloud-native infrastructure, but managing mission-critical workloads requires robust disaster recovery strategies. When running applications on Amazon Elastic Kubernetes Service (EKS), ensuring that your cluster’s resources—deployments, services, persistent volumes, and configurations—are reliably backed up is essential. A single misconfiguration, accidental deletion, or infrastructure failure could disrupt your entire environment. Velero...
How to Setup MySQL Master-Master Replication
Master-Master replication allows two MySQL servers to act as both master and slave simultaneously, enabling bidirectional data synchronization. This setup enhances high availability and distributes write loads across nodes. Below is a step-by-step guide to configure MySQL Master-Master replication. Prerequisites Two servers (Server A and Server B) with MySQL installed. Network connectivity between both servers (port 3306 open). Identical MySQL versions on both servers (recommended). Adjust...
A Complete Guide to MySQL Indexing
MySQL is a powerful relational database management system, and one of its most important features is indexing. Indexing significantly speeds up database queries by reducing the amount of data MySQL needs to scan. In this article, we’ll walk you through setting up MySQL indexes and demonstrate their impact on query performance using a simple Node.js application. What is MySQL Indexing?Indexing in MySQL is similar to the index in a book. It helps you quickly locate data without having to scan...
Configure SSO Authentication in ArgoCD using Okta
This guide walks you through configuring Single Sign-On (SSO) for ArgoCD with Okta as the Identity Provider (IdP) using the SAML protocol. ArgoCD is a declarative, GitOps continuous delivery tool for Kubernetes. It allows you to manage your Kubernetes resources using Git repositories as the source of truth. By configuring SSO with Okta, you can enable users to authenticate to ArgoCD using their Okta credentials. This provides a seamless and secure login experience for users....
