Docker Fundamentals course is intended for absolute beginners. It is recommended for anyone who wants to start working with Docker and it is addressed to sysadmins and developers. It will give you hands on experience creating and managing lightweight, easily deployable containers for your software development projects.
This course will start with an overview of Docker architecture and will proceed with installing Docker. The students will get familiarized with Docker commands and will be able to create and manage containers and images.
The online training for beginners will also cover networking concepts, data persistence in the context of containers and Docker scaling and container orchestration using Docker Swarm.
All these features will be explained and demonstrated with hands on examples in the practice lab.

Target audience:

• DevOps engineers
• Linux system administrators
• Systems design engineers
• Architects

Prerequisites for Docker Fundamentals:
