Nspawn 3.0 introduces a Docker-compatible Engine API for systemd-nspawn containers, allowing tools that use the Docker API like GitLab Runner to manage nspawn machines instead. The host socket at /run/nspawn/api.sock enables the docker CLI to work directly with nspawn containers via the DOCKER_HOST environment variable.
Background
systemd-nspawn is a lightweight container solution within the systemd ecosystem, providing OS-level virtualization on Linux. This update bridges the gap between nspawn and the broader Docker-compatible tooling ecosystem.
