Debian trixie's bundled `nodejs` package is pinned to 20.19.2, which
reached LTS EOL in April 2026. Trixie won't upgrade in place; Debian 14
(forky) — where the apt nodejs is 24.x — isn't released until ~mid-2027.
To stay on a supported LTS without waiting for Debian 14, copy node + npm
+ corepack from the upstream `node:22-bookworm-slim` image as a
multi-stage source, matching the existing `uv_source` and `gosu_source`
patterns in the Dockerfile. Bookworm-based slim image is used so the
produced binary links against glibc 2.36, which runs cleanly on Debian 13
(trixie, glibc 2.41).
Changes:
- Add `FROM node:22-bookworm-slim@sha256:... AS node_source` stage
- Remove `nodejs npm` from `apt-get install` (now sourced from node_source)
- Add `ca-certificates` explicitly to apt install (was a transitive of
the apt nodejs package; removing nodejs broke the chain and curl
inside the build failed with "error setting certificate file")
- COPY node binary + npm + corepack from node_source; recreate the
symlinks at /usr/local/bin/{npm,npx,corepack}
- Update the npm_config_install_links=false comment block — npm 10's
default is already `install-links=false`, but we keep the env as
defense-in-depth against future Node-source-version regressions
Future bumps to Node 24/26 are a one-line ARG change.
Validation:
- Built --no-cache against current origin/main; build succeeds in 1m42s
- Image size: 3.27 GB (pre-salvage-1 baseline) → 3.14 GB (this PR);
net 130 MiB savings (60 MiB from this change alone vs current main —
removing apt nodejs+transitive deps that duplicated what node bundles)
- Node 22.22.3 / npm 10.9.8 / esbuild 0.27.7 all run cleanly under
trixie's glibc 2.41
- Standard image smoke (6/6), Node-version E2E (8/8), chown E2E from
#19788 (6/6), TUI UID-remap E2E from #28851 (4/4) — 24 checks total
