# Simulation Dockerfile
#
# Builds a privileged container for running SPACE simulations (NVRAM, NVMe-oF, etc.)
# Requires Linux host with hugepages support for NVMe-oF simulation.
#
# Build: docker build -t space-sim:latest -f Dockerfile.sim .
# Run: docker run --privileged -e SIM_MODULES=nvram,nvmeof space-sim:latest
