Docker Workshop

This workshop is intended for people who are familiar with Linux and running services like a web server, database, etc.

To make it and easier for everyone, and save us some time please prepare a couple of simple things beforehand. Coming unprepared can cause delays and you might miss the whole workshop because the internet is not fast enough for everyone to download the requirements.

Bring your Laptop - this is a workshop!
It does not matter which operating system you have installed.
