An Overview of Popular Open-Source Kubernetes Tools

This is an article from DZone's 2021 Kubernetes and the Enterprise Trend Report.

Read the Report

Kubernetes is the industry-standard technology used by enterprises to deliver microservices-based container orchestration platforms. The Kubernetes ecosystem is growing rapidly and has a vibrant community that has built several free open-source tools and extensions to make it easier to run your workloads. This article will explain some of the more popular open-source Kubernetes tools used for development, monitoring, and deployment purposes that can improve your cloud-native experience.

Easy Local Development with TiDB

When you develop an application, you begin by coding and testing in your local environment. Many applications interface with a database, so in this early stage, you might use SQLite rather than the database brand used in production. This is an issue, however, because ideally, you want to develop the application with the production database in mind.

When using a distributed system setting up and starting/stopping the components needed for this can become error-prone and time-consuming.

Spinnaker Meets Minikube: Part 3

In the previous posting, we build a Spinnaker pipeline to pull images from Dockerhub to deploy to a Minikube cluster. In this article, we will build a pipeline that deploys to a second staging environment after waiting for the go-ahead from an approval step. Kustomize will, furthermore, be used to illustrate how Spinnaker utilizes its built-in kubectl command to manage configurations from one environment to the next. 

Requirements

The hard yards have been done and it is time for play. Only Kustomize will be added to the soup. Do not despair should you not be familiar with it. This write-up serves as an excellent introduction to Kustomize.

Spinnaker Meets Minikube: Part 2

Introduction

In the previous article, we installed Spinnaker on a Minikube cluster running on Windows 10. In this article, we will add GitHub as a data provider for a Spinnaker pipeline to continuously deploy a dockerized Spring Boot microservice onto the Minikube cluster. The pipeline will be triggered using a Cron job and can be templated so that all one's micro-services are automatically deployed to have a fully up-to-date local development environment at all times. 

Requirements

An understanding of Spring Boot, Github, and Docker Hub is presumed. However, fall-back instructions will be given for those that want to follow a lighter track that pulls the Docker image from the author's registry. However, certain things like proper artifact binding might not work as expected should the full guide not be followed.

Spinnaker Meets Minikube: Part 1

Spinnaker is a continuous integration/continuous delivery tool that was started by Netflix in its quest for more agility. This posting will show how to get hands-on experience running Spinnaker on Windows 10.

Minikube provides the ability to run a Kubernetes cluster on local Linux, Mac, or Windows. It can therefore serve as a sandbox environment for Spinnaker training, experimentation or even to keep ones local development environment up to date with all the latest commits.

Replacing Docker Desktop With hyperkit + minikube

MacOS is a Unix but it isn't a Linux so, unfortunately, if/when we need to use Linux-y things like docker we need to install a VM just like in the Windows world. That's of course also true for docker. 

Like most people, I've been using Docker Desktop for a lot of years to get my fix for containers. It works pretty well, good even for almost everything. I don't remember exactly when Docker desktop added support for running Kubernetes. That looks good on paper and technically it works but not without a price... (at least on my Mac) it also comes with fans a-blazing and the soundtrack of a 747 taking off. Luckily, most of the time I have access to remote Kubernetes servers so I rarely used the option but whenever I did (re)try it, I quickly turned it back off.

My First GoLang Application in Kubernetes

Hi,

In an era of Kubernetes and container-based applications, it is very important to know Go Language as well. Go Lang is one of the popular (might be most popular) languages for developing Microservices or Enterprise Applications in Kubernetes or OpenShift. In this article, we will learn how to deploy the Go application in Kubernetes.

Centralized Logging for Kafka on Kubernetes With Grafana, Loki, and Promtail.

Introduction

In one of my another articles, I discussed how to set up strimzi (also known as Kafka on Kubernetes) on minikube. Also, we discussed how to set up Grafana and Prometheus to fetch metrics from Kafka and zookeeper instances. But wouldn't it have been more helpful and more administrator-friendly if Grafana could also be used to monitor logs of all the pods? If there are multiple zookeeper and Kafka pods, a single window would certainly be a boon for administrators and management.

Grafana provides Loki and Promtail a functionality to aggregate logs and view them from the same Grafana UI.

Skaffold: K8s Development Made Easy

Skaffold is a command line tool developed by Google, which aims to facilitate continuous development for Kubernetes applications. It will automate the task of building and deploying to a Kubernetes cluster whereas you, as a developer, can stay focused on writing code. It seems interesting enough to take a closer look at it!

Introduction

In November 2019 a generally available release was announced promising to save developers time by automating the development workflow. What will Skaffold do for us?
