Docker & Kubernetes: The Practical Guide
Learn Docker, Docker Compose, Development Setups, Deployment and all about Kubernetes from the ground up!
About This Course
Welcome to "Docker & Kubernetes: The Practical Guide"!
Docker & Kubernetes are amongst the most in-demand topics you can learn these days. This course will teach you both from the ground up using a practice-oriented approach!
With Docker, you can create and manage so-called "Containers" - basically packages of code and tools required to run that code. These containers allow you to run your programs in a predictable, environment-independent way - no matter where you need to run it.
For modern DevOps but also for local development - on your own or in a team - this is a winner feature since you will no longer have any "but it worked on my machine" discussions. It works inside of a container, hence it works everywhere!
We'll explore all key concepts in detail and with practical examples and demos - from images and containers, over volumes and networking all the way up to deployment and Kubernetes Clusters: This course has it all!
Why Learn Docker & Kubernetes?
Docker & Kubernetes significantly simplify the development and deployment process of both simple and complex software projects. Especially in web development (though not limited to that), Docker can really take you to the next level!
What's in This Course?
This course will take you from Docker & Kubernetes beginner to advanced level in no time! We'll start at the very basics and dive into all the core features that make up Docker and Kubernetes.
Docker Fundamentals
A thorough introduction to Docker, containers and why you might want to use it. Learn how to create custom images, use existing images and run containers based on such images.
Data & Volumes
Learn how to work with data and how to persist data with volumes. Understand how containers handle data and how to ensure your data survives container restarts.
Container Networking
Explore container networking - with the outside world and between multiple containers. Learn how to connect containers and manage multi-container projects.
Kubernetes Mastery
Understand Kubernetes core concepts & architecture. Learn how to create Kubernetes resources, deployments, services and run your containers with Kubernetes.
In Detail, You'll Learn
This course covers everything you need to master Docker & Kubernetes with multiple real projects where all concepts are applied step-by-step.
Docker Core Concepts
Master these essential Docker skills:
- Thorough introduction to Docker & containers
- Detailed setup instructions for macOS and Windows
- Deep-dive into containers & images
- Creating custom images & using existing images
- Overview of core Docker commands
- Working with data and persisting data with volumes
- Container networking (external & container-to-container)
- Single and multi-container projects
Kubernetes & Deployment
Take your skills to production level:
- In-depth deployment instructions (manual & managed services)
- Deployment with AWS ECS
- Kubernetes core concepts & architecture
- Creating Kubernetes resources, deployments & services
- Working with data in Kubernetes (different volume types)
- Kubernetes networking and DNS service discovery
- Deploying Kubernetes projects (AWS EKS example)
Tons of Demo Projects Included!
You'll find tons of demo projects throughout the course - using programming languages like NodeJS, Python or PHP (with Laravel). You don't need to know these languages to follow along though, no worries! All concepts are taught with slides and theory but also, most importantly, with many examples and demos!
Practice-Oriented Approach!
All these topics are taught in great detail with slides and theory but also, most importantly, with many examples and demos! After finishing this course, you'll be well prepared to work with Docker & Kubernetes in your own projects and apply for DevOps positions!
