Introduction

Kubernetes has revolutionized the way we manage and deploy applications. Its flexibility and scalability make it the go-to platform for developers and operations teams alike. To help you get the most out of your Kubernetes cluster, we’ve compiled a list of ten must-deploy applications. These tools will streamline your workflows, enhance your monitoring capabilities, and even bring some fun into your infrastructure. Let’s dive in!

1. Jenkins

Why Jenkins?

Jenkins is a powerful, open-source automation server that is essential for CI/CD pipelines. It automates the process of building, testing, and deploying your applications, which accelerates development and improves consistency.

Jenkins: Key Features

  • Scalability: Jenkins agents can be scaled up and down automatically.
  • Extensibility: Over 1,600 plugins to support building, deploying, and automating any project.
  • Robust community: A large community for support and development.

A development team uses Jenkins to automate the testing and deployment of a web application. When new code is pushed to the repository, Jenkins triggers automated tests. If the tests pass, Jenkins then deploys the application to the staging environment.
