Convert Docker Compose Files to Kubernetes Manifests with Kompose

Docker Compose make it easy to spin up local development environment with all of application dependencies using a single Compose file. However, when we want to run the same application on Kubernetes, we normally need Kubernetes configuration files such as, deployment, service, etc. In this blog we’ll explore how Kompose works, how to use it to generate Kubernetes configurations from an existing Compose file, and what you should review or modify before deploying the generated manifests to a Kubernetes cluster.

Pre-requisites:

• Docker installed
• Kind installed
• kubectl installed
• An existing Docker Compose file for the application

Managing Kubernetes Clusters Efficiently with K9s Terminal UI

When working with multiple Kubernetes clusters, administrators and developers often use kubectl commands and kube config contexts to switch between clusters. While this is a powerful approach, it requires users to remember various commands and context names, which can become difficult as the number of clusters grows.

For those who prefer a more interactive way to manage Kubernetes environments, tools with user-friendly interfaces can simplify day to day operations. In this blog, we will learn about K9s, a terminal based user interface that provides an efficient way to interact with Kubernetes clusters. K9s enables users to navigate resources, monitor workloads, view logs, and manage clusters directly from the terminal.

Prerequisites: This blog is demonstrated on Windows, and Chocolatey should be installed on your machine.

Troubleshooting Kind Cluster Creation Issues

Kind (Kubernetes in Docker) is a tool used to run a lightweight Kubernetes cluster locally inside Docker containers.

It is a great platform for learning real Kubernetes behavior because clusters can be spun up easily using a single command. In this blog, we will discuss an error that occurred while creating a Kind cluster for the first time and how to resolve it.

Pre-requisites:

• Docker Desktop
• Kubectl installed
• Kind installed
