Course 783:
Essential Docker:
Packaging and Deploying Portable Applications

(4 days)

 

Course Description

This course shows how Docker implements and manage containers. After a short introduction on the use case of containers, the course covers the basics of building and deploying containers. This is followed by the details of images and how to use a container repository. With the basics covered, the course goes on to advanced topics including: automatic provisioning (Docker Machine), data containers, multi-process application in one container, and using many containers with Docker Compose. How to use Docker Swarm for clustering. The new Docker Orchestration is introduced and contrasted with Kubernetes. Then follows an introduction to resource control. The course finishes with a quick look at CoreOS, bare metal containers.
