【rails環境構築】docker + rails + mysql で環境構築中のエラー

Question

前提

dockerでコンテナをたてて仮想環境を構築したいのですが、
「docker-compose run web rails new」
を実行してもアプリケーションができていません。

app,config,db,log,public,test・・・などのアプリが生成されるようにしたいです。

作成したファイル

### "dockercompose.yml"

version: '3'

services:
    db:
        image: mysql:8.0
        environment:
            MYSQL_USER: user
            MYSQL_ROOT_PASSWORD: passw0rd
        ports:
            - "3306:3306"
        volumes:
            - ./db/mysql/volumes:/var/lib/mysql

    web:
        build: .
        command: bash -c "rm -f tmp/pids/server.pid && bundle exec rails s -p 3000 -b '0.0.0.0'"
        volumes:
            - .:/myapp
            - gem_data:/usr/local/bundle
        ports:
            - 3000:3000
        depends_on:
            - db 
        tty: true
        stdin_open: true

volumes:
  gem_data:

FROM ruby:3.0.4
RUN apt-get update -qq && apt-get install -y build-essential libpq-dev nodejs

RUN mkdir /myapp
WORKDIR /myapp

COPY Gemfile /myapp/Gemfile
COPY Gemfile.lock /myapp/Gemfile.lock

RUN bundle install
COPY . /myapp

source 'https://rubygems.org'
gem 'rails', '~>7'

空のGemfile.lockも作成しました。

試したこと

docker-compose logsではエラーは出ていませんでした。

ruby 3.0.4p208
Rails 7.0.4

Answer 1

docker-compose run web rails new , --force --database=mysql --skip-bundle
ではなく
docker-compose run web rails new . --force --database=mysql --skip-bundle
でした。
