I don't know, it just throws an error. Line 12 throws an error. CMD node ./dist/server/entry.mjs

But from the look of it, it doesn't even make it to the full node_modules install.

Hi @mpstaton, thanks for the report!

I followed the guide, using the two given files (Dockerfile and .dockerignore) verbatim and everything worked fine.

By the error you see, I assume you are using the section about SSR on Docker. As it mentions in the docs:

This Dockerfile will build your site and serve it using Node.js on port 4321 and therefore requires the Node adapter installed in your Astro project.

You have to start from a project with the Node adapter, which in turn requires the output to be either "server" or "hybrid". If that config is missing or set to static, or if you are not using the Node adapter, you'll see the error you posted.

Can you check that?
