Introduction: What is IaC?

Today we will become acquainted with a concept known as Infrastructure as Code. The idea of Infrastructure as Code is becoming more and more popular today. IaC is a method used to manage and provision a data center via defined machine-readable files instead of physical hardware configuration or other interactive configuration tools. This article will share what it is used for, why it is important, and why businesses strive to utilize this platform to achieve a desired set of results. It is essential to understand that we will consider both the theoretical and practical parts of IaC.

What is DevOps?

DevOps is a set of various tools, practices, and ideals that combine software development (Dev) and IT Operations (Ops) into a single unifying force. It allows for better collaboration between developers, operations teams, system administrators, and system engineers. Their streamlined goal is to continually provide a high-value software product to the customer at high speed while monitoring and improving the overall process than using traditional software and infrastructure management. 

The web-based Kubernetes console is an interface that provides information about the state of the Kubernetes cluster. The dashboard is also used for deploying containerized applications as well as for general cluster resource management. Traditionally, kubectl is primarily used in the terminal for nearly all cluster related tasks. Still, it is useful to have a visual representation of our cluster in a user-friendly interface. To install the dashboard, kubectl needs to be installed and running on the server.

What is Kubernetes?

In this article, we review what Kubernetes and Kubeadm are, how to install, create a cluster, and set up worker nodes using Kubeadm. If you are not yet familiar with Kubernetes, we recommend reading our article on the fundamental basics of Kubernetes.

Introduction

This article will demonstrate how to install and configure Minikube to set up a small Kubernetes cluster. We will then examine Kubernetes in more detail to apply that knowledge to a real-world example.

What is Kubernetes?

Kubernetes (or K8s) is an open-source container orchestration system for automating computer application deployment, scaling, and management. Kubernetes manages and runs Docker containers on numerous hosts. The project was started by Google and is supported by many companies, including Microsoft, RedHat, IBM.

What is K3s?

K3s is a lightweight version of Kubernetes. It is a highly available Kubernetes certified distribution designed for production workloads in unattended, limited resource, remote locations, or inside an IoT appliance. The developers of K3s declare that K3s is capable of almost everything that K8s can do. 

What is Puppet?

Puppet is a cross-platform client-server based application used for configuration management. It handles the software and its configurations on multiple servers. There are two versions available. One is open-source, the other is a commercial version. It works on both Linux and Windows platforms. It uses a declarative approach to automate updates, installations, and other tasks. This feature allows the software to configure those systems using files called manifests. A manifest contains the instructions for a group or type of server(s) being controlled. 

What is Kubectl?

Kubectl is a command-line tool for Kubernetes. It allows us to execute Kubernetes operations via the API. We can use Kubectl to deploy apps, check logs as well as manage all the other resources of the cluster.

In this tutorial, we will be reviewing what the fundamental similarities and distinctions are between Kubernetes and Docker Swarm. Kubernetes and Docker are two of the major players in container orchestration. Both Kubernetes and Docker Swarm continue to grow in popularity as they are increasingly used by those working with container deployment, orchestration, and management. Across all vertical markets, businesses continue to find new methods of utilization and practice with more uses constantly being discovered.
