# NOTE: Fly.io does NOT support Docker-in-Docker by default.
# To enable Docker socket access (required to spawn project containers),
# you must use a Fly Machine with --privileged flag.
# Run this once after initial deploy:
#   fly machine update <machine-id> --privileged
# Or use the fly-machines.sh helper script included in this repo.
