summary

Boot2container is an initramfs-based system that boots a Linux kernel and then runs containers directly without a full host OS, using podman (and systemd as an entrypoint) to construct a pipeline of containers configured via the kernel command line. It supports booting from USB or iPXE (local PXE or internet), and adds optional volume syncing with S3-compatible storage; it was applied to provide reproducible bare-metal CI test environments and gateways.
