Corso Kubernetes

Obiettivi:

Questo corso porta all'amministrazione completa di un cluster Kubernetes e all'orchestrazione delle applicazioni nei container. Ogni modulo del corso è finalizzato all'apprendimento di teoria e pratica operativa con laboratori specifici dedicati a ogni caratteristica di Kubernetes.

Nel corso viene costruito un cluster Kubernetes da zero on-premises e nei principali cloud provider (AWS, Azure, Google Cloud Platform).

Al termine di questo corso i partecipanti sapranno come amministrare un cluster Kubernetes e prepararsi all'esame CKA.
