# Multi-stage build producing a minimal Node server image for the Cosmos homelab.
|
|
#
|
|
# Stage 1 (builder): install all deps, run astro build -> dist/server/entry.mjs
|
|
# Stage 2 (runtime): copy only dist + prod node_modules, run the Node server
|
|
#
|
|
# The @astrojs/node standalone adapter emits a self-contained server, so the
|
|
# runtime image needs only node_modules + dist. Build once, run anywhere.
