Docker - test environments containerization

This course serves as a practical introduction to work with Docker tool, with major emphasis on possible applications in software tester duties.

It is designed to introduce you to the topics of working with Docker images and most importantly - show and teach practical application of this tool in tester’s and programmer’s everyday work (but not only!). The workshop guides participants from the simple idea of containerization (without superfluous theory) through preparing self-made images right to the final part of building a simple environment composed of a server and automatic tests suite, all run via single command.

The course is geared towards the maximization of practical skills in such a way participants should be able to automate the process of creating, configuring and running test environments and automated test suites on their own from the very next day.
