# BuildKit + metrics-agent sidecar. Socket lives on a shared volume at
# /shared/buildkit so we don't replace BuildKit's own /run/buildkit.
# privileged: true so runc process sandbox can bind-mount (normal BuildKit behavior).
#
# Usage: docker compose up -d
# Metrics: http://localhost:9090/metrics
# buildx: docker buildx create --driver remote tcp://localhost:1234 --use
# Build with --load to load image: docker buildx build --load -f Dockerfile ..
