mecha10-cli 0.1.47

# syntax=docker/dockerfile:1
# Dockerfile.remote - Remote Node Container
#
# This container runs AI/ML nodes (object-detector, image-classifier, llm-command)
# that require platform-specific dependencies (ONNX Runtime, CUDA, etc.)
#
# The mecha10-remote supervisor reads targets.remote from mecha10.json
# and spawns each node using `mecha10 node <name>`.
#
# Uses sccache + BuildKit caches for faster rebuilds.
# See docs/guides/FASTER_BUILDS.md
#
# For standard configurations, use pre-built images from:
#   ghcr.io/mecha-industries/mecha10-remote:<version>
#
# Customize this file only if you need additional system dependencies.
# Changes to this file trigger a local rebuild (pre-built image won't be used).
#
# Auto-generated by `mecha10 init`
