Docker Fundamentals

Who Should Attend

• DevOps engineers
• Linux system administrators
• Virtualization Engineers

• Systems design engineers
• Architects

Prerequisites

• Although the course doesn’t have specific requirements, a good understanding of general OS functionalities and structures will help you to better understand how containerization works.

• Familiarity with Linux command-line also helps you to interact with Docker containers

Course Content

This course is intended for any IT professionals who wants to start working with Docker. At the end of this course, you will have all the main information to understand the core concepts of Docker technologies and how you can use containers in the software development process.
Understanding how containerization in particular works is a great skill nowadays in the DevOps world.

You will get familiarized with Docker commands through hands-on exercises that will give you the chance to get confidence with Docker components. Given the needs of scalability in any IT application implementation and container orchestrations, in this course we will also cover concepts like networking, data persistence and orchestrations with Docker Swarm.

Course Objectives

In the process of learning we will show you some easy ways to learn Docker that will give you at the end of the course a firm understanding of core Docker technologies and key features like:
• Building Docker Images
• Hands-On Labs for creating Docker containers, Dockerfile, Docker Compose,
• Hands-On Labs for working with Docker Networking and persistent data
• Understands Docker Swarm components

After completing this course, students will have a firm understanding of many core Docker technologies and key features including the Docker Hub, Docker Compose, Docker Swarm, Dockerfile, Docker Containers, Docker Engine, Docker Images, Docker Network, Docker Daemon and Docker Storage.
