# Windowsでノンストレスrails new
ファイルとコマンドをコピペするだけでWindows&WSL環境で権限エラーが発生しないrailsのディレクトリを作成できます

※vendorにgemを入れている関係で素のrailsコマンドが使えないので`bin/rails`か`bundle exec rails`コマンドを使いましょう

## ディレクトリとファイルの準備

mkdir deploy_sample
cd deploy_sample
touch Dockerfile.dev
touch compose.yml

## Dockerを使った開発環境の作成
### PostgreSQL(Node.jsあり)
Dockerfile.dev

Bootstrap

docker compose build
docker compose run --rm web /bin/bash -c "bundle init  && bundle add rails"
docker compose run --rm web /bin/bash -c "bundle config set --local path vendor/bundle && bundle in
stall"
docker compose run --rm web bundle exec rails new . -d postgresql -j esbuild --css=bootstrap

Tailwind

docker compose build
docker compose run --rm web /bin/bash -c "bundle init  && bundle add rails"
docker compose run --rm web /bin/bash -c "bundle config set --local path vendor/bundle && bundle in
stall"
docker compose run --rm web bundle exec rails new . -d postgresql -j esbuild --css=tailwind

Procfile.devのwebに` -b 0.0.0.0 -p 3000`をつける

web: env RUBY_DEBUG_OPEN=true bin/rails server -b 0.0.0.0 -p 3000
js: yarn build --watch
css: yarn watch:css

docker compose up

`http://localhost:3000`
