It's 2024 and containers are everywhere. However, it was easy to miss the point where this happened! If you feel you could benefit from a quick "back to the basics" overview, this talk is for you. You will see how containers can be used to make developers' lives easier, how to create your own quickly and efficiently, optimized for your app. Docker Compose setups complete the picture, so you should feel confident about container setups in the future. This talk is almost entirely practical demos, no slides!
