Docker

Docker is a dynamically evolving solution that standardizes containerized vitrualization. Systems built on Docker (e.g. Kubernetes, Openshift) can be used to manage large numbers of containers simultaneously, serving rapidly changing workloads and demands in an automated way.
Docker is an open source system.

What will the participants of the course learn and master during the 2 days?

• The basics of container virtualization
• How to install Docker
• How to manage Docker image files and containers
• Creating your own Docker container image
