Docker Fundamentals Training Course
Duration: 2 days – 14 hrs
Overview
This introductory level course which introduces you to the Docker platform and takes you through installing, integrating, and running it in your working environment. Participants will spend the first two days of the course learning about why Docker exists and the benefits of developing and running your applications on the Docker platform. Each topic covered will consist of a variety of hands-on exercises designed to help you quickly grow from a beginner to a seasoned user.
The course offers learners the opportunity to assimilate basic container orchestration and how to scale Docker across multiple nodes in a simple swarm or Kubernetes cluster. This course provides essential foundational knowledge for subsequent Docker courses.
