DOC-KUB-BSCA - Docker and Kubernetes: Building and Scaling a Containerized Application

Overview

Duration: 3 days
Docker is an open-source platform for automating the process of building, shipping and running applications inside containers. Kubernetes goes one step further by providing the tools needed to deploy and manage containerized applications at scale in a clustered environment.

Objectives

Participants will learn how to create and manage Docker containers, then deploy a sample application inside a container. Participants will also learn how to automate, scale, and manage their containerized applications within a Kubernetes cluster. Finally, the training goes on to more advanced topics, walking participants through the process of securing, scaling and monitoring a Kubernetes cluster.

By the end of this training, participants will be able to:
  • Set up and run a Docker container. 
  • Deploy a containerized server and web application. 
  • Build and manage Docker images.
  • Set up a Docker and Kubernetes cluster. 
  • Use Kubernetes to deploy and manage a clustered web application. 
  • Secure, scale and monitor a Kubernetes cluster. 
  • Format of the course
