Add a management CLI tool and docker-compose.yml for NILRT containers. The script provides discovery, software installation, feed configuration, and system status commands for nilrt-runmode and nilrt-slim containers on a macvlan network. Features: - Discover and list managed containers with status/IP - Install/remove/update packages via opkg with lock-wait - Set up feed configuration in /etc/opkg/base-feeds.conf - Scale container instances via docker compose - Target resolution by name, ID prefix, or numeric index Requires: setup-nilrt-network.sh to create the nilrt-net macvlan network before starting containers.

Changes
Add a Docker Compose configuration and
nilrt-ctr.shCLI for managing NILRT containers locally.docker-compose.yml— Defines two services (nilrtrunmode andnilrt-slim) with shared configuration (privileged, healthcheck on niauth_daemon, macvlan networking via the external nilrt-net network). Supports scaling to run multiple container instances.nilrt-ctr.sh— A Bash CLI that wraps Docker and docker-compose to manage NILRT containers:discover/list/find— enumerate managed containers with status and IP.status— detailed system info (OS, network, services, installed NI software).install/remove/update— package management via opkg with lock-wait.set-feed— configure opkg package feeds.scale— scale service instances via docker compose.shell/exec/logs/rename— operational convenience commands.Requires the nilrt-net macvlan network to be created beforehand (via
setup-nilrt-network.sh).Justification
AB#3201995.
