In this chapter, we learned about the basics of online and Docker-based sandboxes and how to use them optimally. We stressed the need to master the fundamentals of Docker and how to create a basic container from a Dynamics 365 Business Central image from an online repository.
With the skills you've acquired from this chapter, you should be able to create your own containers, choose the right image, and be familiar with the navcontainerhelper tool when it comes to handling your custom sandbox environment.
You should also be able to master Dockerfile formats and perform in-depth modifications of standard images by overriding scripts and creating your own Dynamics 365 Business Central sandbox baseline.
In the next chapter, we will start our development journey by learning about AL language fundamentals.
