Dmitriy Pervin 284894fe40 Add multi-arch Docker build & GHCR publishing (#1278) ... # Summary This PR addresses failures to run Yggdrasil on ARM systems. The root cause was the lack of ARM artifacts/images, which led to exec format error and similar issues. ## What’s added: - ```Dockerfile.multiarch``` — multi-stage Go build that correctly propagates GOOS/GOARCH for linux/amd64, linux/arm64, linux/armhf and linux/armel platform. - ```entrypoint.sh``` - Introduced ENV **ALLOW_IPV6_FORWARDING**. When set to a truthy value (e.g., true), the entrypoint executes: ```sysctl -w net.ipv6.conf.all.forwarding=1```. - GitHub Action for multi-arch builds and publishing to GHCR — triggered via ```workflow_dispatch```, push to ```master``` and release via tags (with docker semantic tags e.g. v0.5.12 → 0.5.12, 0.5, 0). Example published images: [https://github.com/Forne/yggdrasil-go/pkgs/container/yggdrasil-go](https://github.com/Forne/yggdrasil-go/pkgs/container/yggdrasil-go) ## Testing ✅ Ubuntu (24.04, amd64) — image runs correctly. ✅ macOS (Apple Silicon, arm64) — image runs correctly. ✅ MikroTik RouterOS (arm64) — image runs under the RouterOS container package.		2025-10-04 10:51:43 +01:00
