50+ Useful Kubernetes Tools for 2020 - Part 2

Introduction

Last year, we provided a list of Kubernetes tools that proved so popular we have decided to curate another list of some useful additions for working with the platform—among which are many tools that we personally use here at Caylent. Check out the original tools list here in case you missed it.

According to a recent survey done by Stackrox, the dominance Kubernetes enjoys in the market continues to be reinforced, with 86% of respondents using it for container orchestration.

And as you can see below, more and more companies are jumping into containerization for their apps. If you’re among them, here are some tools to aid you going forward as Kubernetes continues its rapid growth.

Understanding the Connection between Minikube's Profile and Kubectl's Context

I discuss the sparsely documented bridging concept that causes Minicube to behave like Kubernetes.

I avoid going deeply into why and how to use or Kubernetes or Minikube. Instead, I focus on how Minikube’s Profile enables training on your local system for Kubernetes on the cloud.

What is Kubernetes?

When Kubernetes was conceptualized, it was started as a Cloud Distributed Operating System (CDOS) for microservices. A “pure” cloud of microservices where complex applications are composed of small independent processes which communicate with each other through APIs (Application Programming Interfaces) over a network.

After all, a cloud is a myriad of heterogeneous hardware, each with its operating systems (bare-metal), that hosts your microservices, which you want to replicate (scale) and start up again if the microservice fails (fault tolerance).

Kubernetes orchestrates the cloud services, starting up and initializing clusters, restarting pods if they become unreachable, replicating (scaling) pods, and many other distributed operating system actions.

Answers to 5 Kubernetes CKAD Practice Questions

We answer hypothetical questions that may appear on the Certified Kubernetes Application Developer (CKAD) exam.

While doing some work with Kubernetes (K8s) and studying for the CKAD exam, I came across a page on Matthew Palmer’s website entitled “Practice Exam for Certified Kubernetes Application Developer (CKAD) Certification” and which contains five practice questions, which I’ll go over here. If you see a problem with anything I’ve done below, including inefficient solutions, please let me know in the comments.

We will focus on not just showing a possible solution to each problem but also verifying our work.

Since we’re limited to the kubernetes.io website when taking this test, this site is referenced where appropriate — in particular the kubectl cheat sheet page is not a bad place to start and we can search for what we need here as well.

Lastly, with each of these questions, we need to pay particular attention to the namespace requirement.

This article relies on minikube running on Ubuntu along with the Oh My Zsh shell.

The k command is defined as follows:

alias k='kubectl'

Let’s take a look at the first question.

Kubernetes in the Cloud: Strategies for Effective Multi Cloud Implementations

Kubernetes is a highly popular container orchestration platform. Multi cloud is a strategy that leverages cloud resources from multiple vendors. Multi cloud strategies have become popular because they help prevent vendor lock-in and enable you to leverage a wide variety of cloud resources. However, multi cloud ecosystems are notoriously difficult to configure and maintain.

This article explains how you can leverage Kubernetes to reduce multi cloud complexities and improve stability, scalability, and velocity.

Kubernetes: Your Multi Cloud Strategy

Maintaining standardized application deployments becomes more challenging as your number of applications and the technologies they are based on increase. As environments, operating systems, and dependencies differ, management and operations require more effort and extensive documentation.

In the past, teams tried to get around these difficulties by creating isolated projects in the data center. Each project, including its configurations and requirements were managed independently. This required accurately predicting performance and the number of users before deployment and taking down applications to update operating systems or applications. There were many chances for error.

Kubernetes can provide an alternative to the old method, enabling teams to deploy applications independent of the environment in containers. This eliminates the need to create resource partitions and enables teams to operate infrastructure as a unified whole.

In particular, Kubernetes makes it easier to deploy a multi cloud strategy since it enables you to abstract away service differences. With Kubernetes deployments you can work from a consistent platform and optimize services and applications according to your business needs.

The Compelling Attributes of Multi Cloud Kubernetes

Multi cloud Kubernetes can provide multiple benefits beyond a single cloud deployment. Below are some of the most notable advantages.

Stability

In addition to the built-in scalability, fault tolerance, and auto-healing features of Kubernetes, multi cloud deployments can provide service redundancy. For example, you can mirror applications or split microservices across vendors. This reduces the risk of a vendor-related outage and enables you to create failovers.
