# @personal-blog/server — EPPP public server application image.
|
|
#
|
|
# [E00-S02-T01/T02/T03] baseline: builds the workspace server package with the
|
|
# pinned toolchain (Node 24.19.0 + pnpm 11.23.0, frozen lockfile) and runs the
|
|
# compiled entrypoint. Since T03 the entrypoint is a minimal Node `node:http`
|
|
# server answering `GET /health` with `{"status":"ok"}` (HTTP 200) on port
|
|
# 3000, so the app container stays up and the health endpoint succeeds. The
|
|
# Fastify 5 application shell (and the real HTTP API) lands in a later story;
|
|
# DB volume persistence (T04) and read-only root filesystem (T06) are
|
|
# Compose-level concerns (see compose.yaml — the `db-data` volume mount and the
|
|
# app service's `read_only: true` + `/tmp` tmpfs; this image is unchanged),
|
|
# while multi-arch build targets (T07) remains a later E00-S02 task — out of
|
|
# scope here. Since T05 the runtime stage drops root privileges (runs as the
|
|
# image's non-root `node` user).
|
|
#
|
|
# Image base: node:24.19.0-bookworm-slim (glibc Debian) per Technology-Stack
|
|
# §5.4 — argon2 is a native dependency and musl/Alpine causes native-module
|
|
# build surprises, so the image must stay on a glibc base.
