Tailwind error when trying to deploy to fly.io

[elfin nacelle]

When trying to deploy my fullstack gleam application, it ends up building everything, my website 'works' but there's no css! I'm using tailwind, everything runs fine using gleam run -m lustre/dev start locally.

I suppose something went wrong building/bundling tailwind, because of the following logs, only i'm not sure what because there doesn't seem to be any error message. Is there something special I need to do to make tailwind work on production deployments?
i tried using the following guide: https://hexdocs.pm/lustre/guide/07-full-stack-deployments.html , but with a few adaptations:

1. i added some extra dependencies after some errors trying to build my frontend

Install build dependencies

RUN apk add --no-cache elixir nodejs npm git

Install Hex package manager for Elixir

RUN mix local.hex --force

2. i decided to build to another folder (i dont want it to build inside my backend folder)

Compile the client code and output to static directory

RUN cd /build/lustre_football_matchmaking
&& gleam add --dev lustre_dev_tools
&& gleam run -m lustre/dev build app --minify --outdir=/build/static

from which afterwards the files get copied:

Copy the compiled server code from the builder stage

COPY --from=builder /build/api_football_matchmaking/build/erlang-shipment /app

Copy the static files to the app directory

COPY --from=builder /build/static /app/static

Am I doing anything wrong/ not up to standards? any recomendations?

See screenshots to see how i serve my frontend in my backend router file:

if you're using an alpine image then currently it wont work, i havent shipped the fix yet

the tailwind binary change how its build from v3 to v4 and now there are separate musl binaries and we dont currently detect when these are necessary

im not too well-versed with docker but if possible i would do the build on an ubuntu container and copy the build frontend to an alpine container for deployment

thanks so much! i'll try it!

you can use a glibc-based image (like basically dropping the -alpine and using that) as the builder and alpine to run it if you care about the image sizes
