Chapter 1: Introduction to DevOps BootCamp

DevOps is currently one of the most sought-after fields in technology. I'm excited to announce a series of articles dedicated to helping beginners navigate their way into DevOps, specifically outlining where to start and which tools are essential for success.

Understanding the DevOps Pipeline

I’ve decided to launch a series of articles titled "DevOps BootCamp Course for Beginners," aimed particularly at software developers eager to delve into DevOps. As a developer with a primary focus on Java, my insights will center on the developer's perspective, addressing how to grasp and learn DevOps effectively. However, this series is open to anyone interested in the field.

Having learned DevOps from the viewpoint of a developer, I possess a solid understanding of both development and deployment processes, having delivered numerous enterprise applications. To embark on your DevOps journey, it’s crucial to have a foundational knowledge of:

1. Application Development
2. Application Deployment

Comprehending the intricacies of how applications are both developed and deployed is vital. Without this knowledge, grasping the essence of DevOps and the learning process becomes challenging. Understanding the issues faced by developers and operations teams will enable you to appreciate how DevOps offers solutions to these challenges.

I faced significant difficulties while learning DevOps due to the overwhelming number of tools available online, which often left me confused about where to begin.

My top recommendation is to focus on Continuous Integration and Continuous Deployment (CI/CD), as this forms the core of DevOps. Once you master CI/CD, it will serve as a guiding principle throughout your learning journey.

In this introductory segment of the DevOps BootCamp course, I will highlight four key tools essential for beginners:

1. Git
2. Jenkins
3. Docker
4. Kubernetes

As a newcomer to DevOps, you might have questions like:

• How do I learn DevOps?
• Where should I start?
• What tools do I need?

By concentrating on these four tools, you will develop a clearer understanding of DevOps, which is fundamentally a cultural approach.

Section 1.1: Tool Overview

#### 1.1.1 Git

Git serves as a version control system that records changes made to your code. It helps track:

1. Who made the changes
2. When the changes were made

If you encounter issues with your current code version, Git allows you to revert to a previous version effortlessly. GitHub acts as a cloud server for Git, where you can work on your code locally and upload it to the GitHub repository once your tasks are completed. This serves as a centralized location accessible to all developers for reading and writing.

Issues like file overwriting will be addressed, along with best practices for using GitHub.

#### 1.1.2 Jenkins

Jenkins is a vital tool for CI/CD processes. It functions similarly to an Enterprise Resource Planning (ERP) application and is typically installed on a cloud server. Jenkins retrieves code from GitHub, builds and tests it, and then deploys the final product to various environments—development, testing, or production.

In simple terms, CI/CD refers to the automatic transition of the latest code from GitHub to the designated server, and Jenkins facilitates this process.

#### 1.1.3 Docker

Many newcomers struggle to grasp the concept of Docker. Here’s a straightforward explanation:

Imagine you’re developing an application that requires a specific library for generating PDFs. If you’re working on Windows but deploying to a Linux server, you must install the necessary libraries separately before deployment. This can lead to numerous complications.

Docker resolves this issue by allowing you to package your application and its dependencies into a single unit, known as an OS image. This makes it easy to transfer your application from one operating system to another.

#### 1.1.4 Kubernetes

The initial understanding of Kubernetes can also be daunting. To clarify:

Running multiple instances of Dockerized applications across a cluster (a network of computers or nodes) can be challenging. Kubernetes, as a container orchestration tool, enables you to manage and run multiple Docker containers across a cluster from a single point.

Summary

This introduction to the DevOps BootCamp course for beginners outlines my journey in learning DevOps from a developer's perspective. With an abundance of tools available, it can be confusing to know where to start. My goal is to simplify this process. CI/CD is the cornerstone of DevOps, so prioritize learning it to dispel any uncertainties you may have.

Once you grasp CI/CD, your understanding of DevOps and its tools will deepen, helping you identify which tools are crucial for your career. It's important to remember that not every tool is necessary, and you can’t learn them all.

As a beginner, I recommend focusing on the four tools mentioned earlier to set you on the right path.
