Watcher not working in Docker even with `tty:true`

[dseravalli]

The CSS is built successfully when I first docker-compose up but doesn't rebuild when I edit and save files.

Rails 7.0.4.3 tailwindcss-rails 2.0.29 MacOS Sonoma 14.2 Orbstack 1.3.0

tailwind.config.js content

  content: [
    './public/*.html',
    './app/helpers/**/*.rb',
    './app/javascript/**/*.js',
    './app/views/**/*.{erb,haml,html,slim}',
    './node_modules/flowbite/**/*.js',
  ],

docker-compose

version: '3.9'
services:
  app:
    tty: true
    build:
      context: .
      dockerfile: Dockerfile.dev
    ports:

Dockerfile.dev

CMD ["./bin/dev"]

Procfile.dev

web: bin/rails server -p 3000 -b 0.0.0.0
css: bin/rails tailwindcss:watch

/bin/dev

#!/usr/bin/env sh

if ! gem list foreman -i --silent; then
  echo "Installing foreman..."
  gem install foreman
fi

exec foreman start -f Procfile.dev "$@"

I had some issues with this as well, and solved it by adding the puma module to puma.rb rather than running everything within foreman or running a dedicated compose container. However, it still required me to add tty: true to the compose entry for the rails server.

Sorry to hear you're having trouble with this feature. There are two other options you can try to use, which are documented in the README:

• tailwindcss:watch[poll]
• tailwindcss:watch[always]

Please note that this gem doesn't implement the file watching; we're using the upstream tailwindcss executable's watch features for this. If you can't get it to work with either of these other options, you may want to ask for support upstream.
