Sometimes you need a special configuration for your notebook's environment—and you don't want to wait for that code to run every time you start up a notebook. This includes having to wait for libraries to install, packages to be downloaded, configuration files to be set, and more.

These resources will teach you how to set up a custom environment with a local Dockerfile in Deepnote. Once created, Deepnote will host and cache the image for you so that you can begin your work straight away.

In the example notebook and video below, I show how to set up an R environment that uses SQL to query a Snowflake database.
