Tiny Docker VM distro. Boot2Docker has been discontinued; the active alternatives listed here are maintained products you can switch to.
Windows and macOS developers in the early Docker era (roughly 2013-2016) who needed to build and run Linux containers on a platform without native Linux container support.
A minimal Linux distribution, based on Tiny Core Linux, purpose-built to run the Docker daemon and boot entirely from RAM for a fast, small footprint. It shipped as a VirtualBox VM image managed by a companion boot2docker CLI, which handled VM lifecycle, SSH access, and forwarding the Docker socket to the host. It included just enough OS to host Docker and its dependencies, not a general-purpose Linux environment.
Users installed VirtualBox and the boot2docker CLI, then ran boot2docker init and boot2docker up to create and start the lightweight VM; the CLI configured environment variables so the local docker client on the host could talk to the Docker daemon running inside the VM. It was later superseded by Docker Machine/Docker Toolbox and eventually native Docker Desktop.
