# syntax=docker/dockerfile:1.6
# =============================================================================
# Nika CLI — Multi-Stage Docker Image
# =============================================================================
#
# Stage 1 (builder): Rust build environment for testing
#   docker compose -f docker-compose.test.yml --profile unit up
#
# Stage 2 (runtime): Minimal scratch image with pre-built static binaries (~5MB)
#   docker run --rm ghcr.io/supernovae-st/nika:latest --version
#
# Build context for runtime (created by CI):
#   docker-context/
#   ├── amd64/nika    (x86_64-unknown-linux-musl binary)
#   └── arm64/nika    (aarch64-unknown-linux-musl binary)
#
# Usage:
#   docker run --rm -v $(pwd):/workspace ghcr.io/supernovae-st/nika:latest run workflow.nika.yaml
#
# Note: Runtime uses --no-default-features (no OS keychain). Use env vars:
#   -e ANTHROPIC_API_KEY="sk-ant-..."
