Docker and Kubernetes Fundamentals

3 Days

Description

Are you a developer, architect, or technical team lead without a foundational understanding of Kubernetes and Docker? To meet the demands of your workplace, you will need to have a strong grasp of the Kubernetes and Docker technologies in the development, production, and staging environments.

This 3-day intensive Docker and Kubernetes Training course offers a combination of theoretical learning and actional labs, so you have the opportunity to apply your knowledge in a hands-on setting. The course covers essential Kubernetes and Docker skills, as well as a basic introduction to Continuous Integration.

Objectives

Learn the fundamental uses of container technology and the architectural principles of how to apply containers to technical challenges.
Create containers with both packaged solutions and custom software.
Use the Docker and Kubernetes CLI environments to deploy solutions in local (Docker) and cluster (Kubernetes) environments.
Learn how stateful services – such as databases, streaming solutions , and other specialty applications – can be deployed in highly-available configurations with redundancy and service-discovery/load-balancing.
Show how other components – can be used to integrate services within the Kubernetes platform.
Explore how Docker and technologies such as Jenkins can be used to continuously test and build containers based on changes to source code.
