Description
Switched to pinned Go 1.24 & Alpine 3.22; used a two‑stage BuildKit build with cache+SSH mounts to compile, then copied only the bor binary into a tiny Alpine runtime (just certs, no toolchain or Bash)—slashing the image from gigabytes to a few hundred megabytes.
This mirrors exactly what Geth’s Dockerfile does; see their approach here:
