Based on a previous blog post, this devcontainer is now publicly available as a template for anyone to use at Dev Container Templates and integrated with publicly available Codespace images.

When you start a Codespace for a project, it will try to use whatever Dev Container you have specified in your repo, else it will try to use a kitchen sink container. That default kitchen sink is can be way too much and so if you will be working with Conda environments with an Anaconda or Miniconda Dev Container template instead.

This example uses the Docker in Docker dev container. There are others that may suit you better, feel free to customize to your needs. This example doesn’t rely on the exact type of dev container used.

there are already built docker images for common development environment. You can either use one of them, or build one from Docker file. Using a pre-built dev container doesn't mean you are only limited to that image, because you can still add other tools, which they are called features to that image. For a list of the pre-built templates check here, and for the other features that you can add check this. You don't need a Docker file, unless you want to build your dev environment step by step.
