Creating development setups can be tedious, error-prone and quite horrifying to novice contributors of Open Source projects. You would set up a virtual machine, install the required software and spend quite some time configuring it. On top of this, your setup would require maintenance and updates. A more modern approach is featured in this talk: Create a reproducible environment, have automatic updates to new package versions just by using OBS to build your Docker container image from RPMs and a kiwi XML file. No more fiddling with VMs, no more manual install and configuration marathons - just download and run your ready-to-use Docker image from OBS.
