Convert to Docker (Current Runtime Policy)

This repository now supports two runtime modes:

• docker (preferred/default)
• host (advanced, explicit opt-in)

This skill enforces Docker-first configuration and verifies the runtime end-to-end.

1. Verify Docker Is Installed and Running

docker --version
docker info >/dev/null && echo "Docker ready" || echo "Docker not ready"

If Docker is missing:

• macOS: install Docker Desktop from https://www.docker.com/products/docker-desktop/
• Linux: curl -fsSL https://get.docker.com | sh && sudo systemctl start docker

2. Set Docker Runtime Defaults

Update .env so Docker is selected and host-mode overrides are removed:

# ensure runtime is docker-first auto mode
if grep -q '^CONTAINER_RUNTIME=' .env 2>/dev/null; then
  sed -i.bak 's/^CONTAINER_RUNTIME=.*/CONTAINER_RUNTIME=auto/' .env
else
  echo 'CONTAINER_RUNTIME=auto' >> .env
fi

# remove host runtime opt-ins if present
sed -i.bak '/^FFT_NANO_ALLOW_HOST_RUNTIME=/d' .env
sed -i.bak '/^FFT_NANO_ALLOW_HOST_RUNTIME_IN_PROD=/d' .env

3. Build Runtime Artifacts

./container/build.sh
npm run build

4. Verify Agent Runtime

echo '{}' | docker run -i --entrypoint /bin/echo fft_nano-agent:latest "Container OK"

5. Verify Setup Path

Run the project setup checker (Docker path):

bash scripts/setup.sh

Expected behavior:

• Detects Docker runtime
• Builds/uses Docker image
• Passes runtime smoke checks

6. Restart Service

launchctl kickstart -k gui/$(id -u)/com.fft_nano

Notes

• Do not set CONTAINER_RUNTIME=host unless explicitly requested.
• Host mode is intentionally gated by FFT_NANO_ALLOW_HOST_RUNTIME=1.
• Docker is the supported default for parity and operational consistency.
