[Data Science dev containers] Do they work with bind mounts?

Docker: https://docs.docker.com/storage/bind-mounts/
Podman: https://docs.podman.io/en/latest/markdown/podman-run.1.html#mount-type-type-type-specific-option

Yes.

By default, mount type volume is used, so Dev Containers behave the same as Codespaces.

When working with Docker Desktop, volumes are more performant than bind mounts.

To work with a bind mount, e.g. modify the devcontainer.json for Python base as follows:

diff --git a/.devcontainer/python-base/devcontainer.json b/.devcontainer/python-base/devcontainer.json
index b31e40c..dae65cc 100644
--- a/.devcontainer/python-base/devcontainer.json
+++ b/.devcontainer/python-base/devcontainer.json

ℹ️ This will mount <root-of-this-repository>/.bind-mounts/python-base-home-vscode to /home/vscode in the Dev Container.
