Docker and Podman (XAM-CONT-1)

 

Course Overview

Docker has made application containers the quasi-standard for cloud native application delivery. Docker combines management tools for containers, networks, and volumes with a rather simple mechanism for automating the creation of container images. These principles also apply to the Docker alternative Podman. In addition to the administration of containers, it is necessary to package applications in container images, to precisely understand the requirements of containerized applications and to optimize applications specifically for containerized runtime environments. This course teaches all the essential features of Docker and Podman with numerous exercises.

This course is delivered in cooperation with the xamira networks GmbH.

Who should attend

The training is aimed at developers and administrators as well as architects and decision-makers with a high level of technical interest.

Prerequisites

The participants have to master the basics of Linux system administration. They need to be proficient in using the command line, editing files on the command line, and managing system services.

Course Objectives

Participants learn how to use application containers with Docker and/or Podman. This includes configuring individual containers, networks, and volumes, as well as orchestration with Docker Compose. In addition, participants will learn how to create Dockerfiles / Containerfiles for packaging applications in container images.
