Introduce a multi-stage Alpine Dockerfile that cross-compiles via buildx ($BUILDPLATFORM -> $TARGETARCH) so a single invocation produces both linux/amd64 and linux/arm64 images without a qemu-emulated builder. `make docker` loads the native-arch image locally for smoke tests; `make docker-push` publishes a multi-arch manifest. Ship a docker-compose.yaml with opt-in profiles for maglevd/frontend and a .env.example template so operators can mirror /etc/default/vpp-maglev muscle memory into containers.

# docker-compose.yaml — vpp-maglev{d,-frontend} container stack
|
|
#
|
|
# Two services built from a single multi-stage Alpine Dockerfile:
|
|
#
|
|
# maglevd -> git.ipng.ch/ipng/vpp-maglevd:latest (health-checker daemon)
|
|
# frontend -> git.ipng.ch/ipng/vpp-maglevd-frontend:latest (read-only web dashboard)
|
|
#
|
|
# Both services are opt-in via Docker Compose "profiles". Copy
|
|
# .env.example to .env, set COMPOSE_PROFILES to include the
|
|
# services you want, and run:
|
|
#
|
|
# docker compose up -d
|
|
#
|
|
# See .env.example for every tunable. See README.md for the
|
|
# operational overview.
