R6: static-binary packaging + remote-relay deploy docs#5
Merged
Conversation
Completes beacon R6. - Makefile: `make build` produces a static (CGO_ENABLED=0), trimmed, version-stamped binary in dist/; cross-compiles via GOOS/GOARCH. `make check` mirrors the CI quality gates. - deploy/beacon.service: a hardened systemd unit for a remote relay — unprivileged service account, strict sandbox (beacon holds no database and writes nothing at runtime). - docs/DEPLOY.md: end-to-end guide for a remote relay — build, host prep, CSR-over-SSH enrolment, the unit, the inbound-only firewall surface, and cert rotation. The embedded relay needs no deployment; helm runs it in-process. Signed-off-by: Khalefa <Khalefa@alahmad.org>

beacon milestone R6 — packaging & deploy
The final beacon milestone: package the relay as a static binary and
document deploying a remote relay.
Added
Makefile—make buildproduces a static (CGO_ENABLED=0),-trimpath, version-stamped binary indist/; cross-compiles viaGOOS/GOARCH.make checkruns the same gates as CI(
fmt/vet/test/lint).deploy/beacon.service— a hardened systemd unit: unprivilegedbeaconservice account,ProtectSystem=strictand a full sandbox.beacon holds no database and writes nothing at runtime, so it needs
no write access.
docs/DEPLOY.md— end-to-end remote-relay guide: build, hostprep, CSR-over-SSH enrolment, installing the unit, the inbound-only
firewall surface (
--client-addrfor caravel,--tunnel-addrforhelm), verification, and cert rotation.
The embedded relay needs no deployment — helm runs it in-process
(docs/HELM-INTEGRATION.md).
Quality

With this, R1–R6 are all complete — skeleton, transparent proxy,
embedded + remote transports, relay enrolment, and packaging.
