Container Management with Docker (2 Tage/ 14 Stunden)

Description

Dieser Kurs vermittelt in den ersten beiden Tagen die grundlegende Verwendung von Docker , die sowohl für Entwickler als auch für Systemadministratoren nützlich ist. Der Kurs beinhaltet viele praktische Übungen und die Teilnehmer üben in ihrer eigenen Docker Umgebung und erstellen ihre eigenen Docker Images.

Am letzten Tag werden die Teilnehmer mehr über erweiterte Tools erfahren, die Docker unterstützen. Es werden Docker Machine, Docker Compose und Docker Swarm sein.
