Single Go binary with five commands: - build: podman build locally with registry tags + git version - push: podman push to MCR - deploy: SSH pull/stop/rm/run on target node - cert renew: issue TLS cert from Metacrypt via REST API - status: show container status on a node Config-driven via TOML service registry describing images, Dockerfiles, container configs per node. Shells out to podman for container operations and ssh for remote access. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
