# Pre-baked CI base image for Woodpecker pipelines.
#
# Purpose: eliminate the cold `pnpm install` that dominates every pipeline
# (~731s median). This image ships the native toolchain (no per-run `apk add`)
# AND a warm, content-addressable pnpm store with the dependency-tree tarballs
# already fetched at build time. `pnpm fetch` only populates the store from the
# lockfile — it does NOT run the native node-gyp builds (better-sqlite3,
# node-pty, sqlite3, canvas, sharp); those still compile at `pnpm install`,
# which is exactly why the musl toolchain stays baked into this image. A
# pipeline `pnpm install --frozen-lockfile --prefer-offline` then resolves
# tarballs from local hard-links (no network) and compiles natives against the
# already-present toolchain, in tens of seconds instead of ~731s.
#
# Rebuilt only when `pnpm-lock.yaml` or this Dockerfile change
# (see .woodpecker/ci-image.yml).
#
# Node version is intentionally pinned to 22 (Active LTS at time of writing).
# The node:22 -> node:24 bump lands as a SEPARATE follow-up PR so the cache
# change carries zero runtime-version variables.
FROM node:22-alpine

# Native toolchain required to compile node-gyp deps on musl, plus the
# postgresql-client used by the test step's pg_isready readiness probe. `bash`
# is baked here too — the sanitization step in ci.yml otherwise does a per-run
# `apk add bash`.

# Warm the store. `pnpm fetch` populates the content-addressable store with the
# dependency tarballs directly from the lockfile (no package.json / workspace
# needed), so a baked store stays valid until the lockfile changes. Note:
# `fetch` does NOT compile native modules — that happens later at `pnpm install`
# in the pipeline, against the toolchain baked above.
