Running postcss in docker

[kurotych]

I want to use a theme (https://github.com/google/docsy) but I don't want to install any NodeJS garbage on my host machine.

As a workaround, I created a Dockerfile, wrapped script and rebuilt hugo

FROM node:20-alpine

WORKDIR /usr/src/app

RUN npm install -g postcss postcss-cli autoprefixer

CMD [""]

docker build -t postcss .

❯ cat postcss

#!/bin/bash
docker run --rm -i postcss postcss "$@"

Rebuild Hugo with a changed next-line because Npx function adding the npx prefix that I don't need.

hugo/resources/resource_transformers/postcss/postcss.go

Line 203 in ee26e69

cmd, err := ex.Npx(binaryName, cmdArgs...)

=>

ex.New(binaryName, cmdArgs...)

It'd be nice to have a configurable binary path to the postcss to make it possible to call without npx prefix.
