Docker -Beyond the Basics

Course Overview

Docker is an open-source platform that enables application developers, network and system administrators, and others to access and deploy the latest, updated images into their respective environments. An in-depth understanding of Docker ensures the availability of up-to-date software applications for quality assurance and production environments. This series of courses covers some advanced Docker skills for managing images, working with the Dockerfile, and managing volumes. This series also covers the advanced networking techniques in Docker.

Target Audience

Technical managers, operations staff, application developers, network administrators, system administrators, and anyone interested in learning about advanced Docker features. A prior knowledge of Docker is assumed.

Course Objectives
