DevOps Hello World

My Journey from Code to Kubernetes

Hey there, fellow tech enthusiasts and DevOps aficionados! Welcome to my DevOps Hello World tutorial. Over my 15 years of experience in the ever-evolving realm of DevOps, I've seen technology grow by leaps and bounds. In this tutorial, we'll embark on an exciting journey together, taking a FastAPI application and guiding it through the intricate landscape of modern DevOps practices.

Whether you're a seasoned developer looking to embrace DevOps methodologies or a curious newcomer eager to understand the intricate art of containerization and orchestration, this tutorial is your gateway. By the end of our journey, you'll have a hands-on grasp of the entire DevOps lifecycle, from code inception to deployment on a Kubernetes cluster.

While Google Sites offers a user-friendly platform for various tasks, I've found it somewhat clunky for the purposes of this tutorial. This high-level overview serves its purpose, but for those seeking more detailed, granular information, I strongly recommend visiting my GitHub repository at DevOpsHelloWorld. There, you'll find in-depth materials and resources that complement and expand upon what's presented here.

Let's break down our adventure into distinct stages:

1.  Setting up a FastAPI Application:

We'll kick things off by creating a FastAPI application, a Python-based web framework, to serve as our project's core.

2. Harnessing Visual Studio Code:

Leveraging the power of Visual Studio Code, a beloved IDE among DevOps pros, we'll code efficiently and manage our project seamlessly.

3. Embracing Version Control with GitHub:

Next, we'll dive into the world of version control, setting up a GitHub repository to meticulously track our code changes and foster effective collaboration.

4. Containerization Magic with Docker:

Now, we'll delve into the art of containerization, encapsulating our FastAPI application within a Docker container. This practice enhances portability and simplifies deployment.

5. Sharing on Docker Hub:

Learn the ropes of sharing your Docker image with the global tech community by publishing it on Docker Hub, the go-to container registry.

6. Running Containers with Ease:

Discover how simple it is to deploy your application from the container registry, allowing others to run your work effortlessly.

7. Kubernetes Deployment Mastery:

Finally, we'll explore Kubernetes, the crown jewel of container orchestration. We'll deploy our containerized application on a Kubernetes cluster, unlocking the full potential of scaling and managing applications.

By the end of this tutorial, you'll have traversed the DevOps landscape, gaining insights into the workflow, and honing your skills with the tools and practices that define modern software development and deployment.

So, without further ado, let's embark on our DevOps odyssey and get ready to say "Hello World" to a world of DevOps possibilities! Join me as we dive headfirst into setting up our FastAPI application.
