This docker-in-docker Dev Container Feature is roughly based on the official docker-in-docker wrapper script that is part of the Moby project. With this in mind:
- As the name implies, the Feature is expected to work when the host is running Docker (or the OSS Moby container engine it is built on). It may be possible to get running in other container engines, but it has not been tested with them.
- The host and the container must be running on the same chip architecture. You will not be able to use it with an emulated x86 image with Docker Desktop on an Apple Silicon Mac, like in this example:
See Issue #219 for more details.

This Feature should work on recent versions of Debian/Ubuntu-based distributions with the apt package manager installed.
Debian Trixie (13) does not include moby-cli and related system packages, so the feature cannot install with "moby": "true". To use this feature on Trixie, please set "moby": "false" or choose a different base image (for example, Ubuntu 24.04).
bash is required to execute the install.sh script.
