Kubernetes and Docker Online Course

About the Course

Containers are empowering businesses to scale fearlessly and manage their web applications hassle-free. They are the prime reason why micro and small enterprises are migrating to the cloud. All of this has undoubtedly led to an enormous demand for professionals with containerization skills. This course is a comprehensive explanation of what you should do to successfully build and run containerized applications using Docker and Kubernetes.

The course starts with an introduction to Docker and explains how it helps in developing web applications. Next, you will explore the architecture of Docker and become familiar with Docker images, Docker files, and containers. Moving along, you will work with the Container Networking Model (CNM) and Docker storage and get an introduction to Docker Compose. Towards the end, you will learn to perform container orchestration with Docker Swarm and pods and get to grips with the concepts of Kubernetes.

By the end of this course, you will have all the skills needed to build, deploy, and manage containerized web applications on local premises and on the cloud using Kubernetes and Docker.
