Docker is an open source tool that simplifies managing Linux containers. A container is a sandbox environment that runs a collection of processes. Containers are light-weight VMs that share the same kernel as the host OS.
Docker adds some niceties to Linux containers such as AUFS, version control, docker registry (repository), versioning etc.

We attended a presentation introducing docker concepts, how it works and why is the difference between a container and a VM
Hands on experience covering:
1. Set-up Docker
2. Start a container
3. Create an image
4. Save the image on docker registry
