Kubernetes has become an indispensable tool in modern application development. This cluster management system revolutionized the way containerized applications are managed across multiple hosts. Since its release in 2014 by Google, Kubernetes has powered the Google Container Engine, which is an integral part of the Google Cloud Platform. Today, it serves as the foundation for numerous innovative products and services. In this article, we will explore the top ten most useful Kubernetes open-source projects that you should keep an eye on in 2023.
1. Helm: Simplify Kubernetes Application Management
About Helm
Helm is a highly popular open-source package manager designed specifically for Kubernetes. It provides users with an efficient way to manage Kubernetes applications. Helm leverages a packaging format known as charts, which are collections of files defining a set of related Kubernetes resources. With Helm, you can deploy anything from a single Memcached pod to an entire web app stack comprising HTTP servers, databases, caches, and more. Helm charts simplify the process of defining, installing, and upgrading applications, making it an invaluable tool for Kubernetes application management.
