From Docker Swarm to Kubernetes: Transitioning and Scaling

In the ever-evolving landscape of container orchestration, the shift from Docker Swarm to Kubernetes has become a significant trend. As organizations seek more robust, scalable, and reliable solutions for deploying and managing containerized applications, Kubernetes emerges as the clear frontrunner. This article delves into the nuances of transitioning from Docker Swarm to Kubernetes, focusing on best practices, strategic considerations, and the scaling advantages Kubernetes offers.

Understanding the Shift

Docker Swarm, Docker's native clustering and scheduling tool, provides simplicity and ease of use but often falls short in handling more extensive and complex deployments. Kubernetes, on the other hand, is an open-source platform designed to automate the deployment, scaling, and operation of application containers. It offers greater flexibility, a richer feature set, and a vast ecosystem, making it the preferred choice for large-scale, enterprise-level deployments.

Expose Your App to The Internet Using Ingress Controller

Do you have many internet-facing applications and worried about the cost of Load Balancer? Well, this article will help you expose your applications to the Internet using a single Load Balancer, saving you hundreds of dollars.

What is Ingress?

Let us first understand what Ingress is. An Ingress is an API object that manages external access to the services in a cluster and may provide load balancing, SSL termination, and name-based virtual hosting.

Scalable Jenkins on Kubernetes Cluster and Pipeline for Automated CI/CD (Jenkins—Github Integration)

Introduction

Setting up scalable Jenkins on Kubernetes can be a daunting task. This article demonstrates not only how to set up scalable Jenkins on Kubernetes but also how to integrate Jenkins into Github so that whenever any Pull Request is requested on a branch, the build is automatically triggered and results are made available to the branch admin to review before merging the Pull Request.

Let us first get the scalable Jenkins up before setting up a pipeline for automated CI/CD.
