# Two-stage build needing ZERO outbound network at image-build time:
|
|
# (a) deps are installed by the CI job / dev host (`bun install`) and copied in via the
|
|
# build context — the runner's dind daemon has broken outbound DNS for build containers,
|
|
# so any RUN that fetches packages fails;
|
|
# (b) base images must be glibc (node:22-slim), NOT alpine/musl: native modules (@next/swc-*,
|
|
# sharp) are prebuilt for the platform that ran `bun install` — CI job and prod host are
|
|
# x86_64 glibc linux. Building on another platform requires reinstalling node_modules there first.
