Description

Welcome to Docker and Kubernetes for Beginners: From Zero to Hero! Are you ready to dive into the world of containerization and orchestration with the industry's leading tools? This course is designed to take you from a beginner to a proficient practitioner, equipping you with an in-depth understanding of Docker and Kubernetes concepts.Why Learn Docker and Kubernetes?Docker and Kubernetes have revolutionized the way we develop, deploy, and manage applications in modern architectures. Here's why learning these technologies is essential:Gain Highly Demanded Skills: Docker and Kubernetes are everywhere, and companies need people who can work effectively with these tools! By learning them, you'll make yourself more attractive to employers in the tech industry and enhance your career prospects for promotions, new job opportunities, and potentially higher salaries. You'll stand out in the job market!Improve and Streamline the Development Process: Docker enables you to package applications with all their dependencies into isolated and portable containers, ensuring consistency across development, testing, and production environments.Master Application Deployment, Scaling and Management: Kubernetes will enable you to deploy, manage, and scale applications automatically, making complex tasks such as rolling out new application versions and managing advanced system architectures much simpler.Learn Versatile Tools: Docker and Kubernetes are platform-agnostic, which means that your knowledge will be valuable and applicable independently of which platform you are using to run them! Whether it's on-premises, on AWS, GCP, or Azure, knowing how to work effectively with Docker and Kubernetes will make you a great contributor to your projects!By investing time in learning Docker and Kubernetes, you're not just adding tools to your toolbox—you're enhancing your professional value, opening doors to new opportunities, and equipping yourself with skills that will serve you throughout your career!Why Should You Choose This Course?This course offers a unique blend of theoretical knowledge and practical application, providing a comprehensive understanding of Docker and Kubernetes. Here's why you should include this course in your learning journey:Learn by Doing with Hands-On Exercises: I truly believe in the power of learning by doing. I've not only crafted more than 100 hands-on lectures for you to practice what we discuss, I've also included all of them as written exercise guidelines for you to try and experiment as much as you want before watching the solution recordings! The exercises build on each other and increase gradually in complexity, deepening your understanding and skills while discussing relevant topics of working with Docker and Kubernetes!Comprehensive, Real-World Projects: We'll also go beyond individual hands-on exercises on Docker and Kubernetes, and we'll practice deploying entire applications by going through the entire cycle of coding, building, publishing, and running them!Go Beyond the Purely Technical Points: I place a strong focus on going beyond the "this is how you do it", copy-paste approach. My genuine interest is to teach you how these tools work behind the scenes, how you reason about their behavior, how you debug common issues and situations, and how you make the best use of them in your day-to-day.Real-World Kubernetes Experience with Google Cloud: Our final project is to deploy our application to a managed Kubernetes cluster in Google Cloud. This will give you hands-on experience not only with Docker and Kubernetes, but also with how these tools behave in a managed, real-world setup like Google Kubernetes Engine (GKE).Expert Guidance: I bring several years of experience as a Senior DevOps Engineer, Infrastructure Consultant, and IT trainer within one of the leading IT consulting companies worldwide, and I'm super excited to share my knowledge with you!Which Skills Will You Acquire During This Course?As you go through this course, you will gain a comprehensive and valuable set of skills, including:Creating and Distributing Docker Images: you will learn how to build, customize, optimize, and distribute Docker images using best practices. Running and Managing Containers: you will learn the many aspects related to running containers using Docker, Compose, and Kubernetes, and you will gradually understand how these tools fit together and tackle challenges at different levels of running and managing software applications.Docker Networking and Security Essentials: you will gain a solid foundation on security aspects related to running containers, as well as how to connect containers together using multiple networking solutions.Understanding the Kubernetes Architecture: you will gain a deep and solid understanding of the different components of a Kubernetes cluster, their functions, and how they interact together to deliver this amazing system.Running Applications, Persisting Data, and Managing Resources in Kubernetes: this course takes a deep dive into the many objects Kubernetes offers to run applications, both stateless and stateful, as well as into multiple dimensions of managing compute resources and Kubernetes objects effectively.Kubernetes Security Fundamentals: you will acquire a strong sense of why security is important in Kubernetes, and the many areas where security plays a role in our applications. We will also take a deeper dive into how to set Role-Based Access Control (RBAC) rules, network policies, and pod security standards to ensure your workloads have an additional layer of security.Working with Managed Kubernetes Clusters: you will go through the entire process of creating a cloud account with Google Cloud, all the way to having your applications up and running in a Kubernetes cluster and reachable from the internet securely! This will give you a thorough understanding of how managed Kubernetes services make our lives as developers much easier by integrating multiple services from cloud providers.Get ready to elevate your career with our Docker and Kubernetes for Beginners: From Zero to Hero course.
