Linux Basics for Containers and the Cloud

Course Description

Understanding and using Linux as the basis of containers and cloud instances.

Linux is the base of almost all cloud native infrastructure. Whether in containers under Docker and Kubernetes or in IaaS instances in the cloud, modern software runs on Linux. Fundamental skills in using Linux are therefore indispensable for anyone who develops, delivers or operates software. This course explains Linux basics with a focus on the topics that are particularly relevant in containers and in the cloud.

Course Objectives

The participants learn how to use Linux systems. This includes interacting with a Linux system, installing software, dealing with processes, files, user accounts and permissions, as well as network access and basic security measures. The participants understand how Linux is deployed in containers and in the cloud and how the configuration of these installations can be automated.
