Q&A
dockerでのrails開発環境構築でのエラーです。
docker 2.3.0.3
rails 5.0.0
ruby 2.3.6
にて、dockerコンテナ上でrailsの開発環境を構築しようとしています。
dockerfile
FROM ruby:2.3.6 RUN apt-get update -qq && apt-get install -y build-essential nodejs RUN mkdir /app WORKDIR /app COPY Gemfile /app/Gemfile COPY Gemfile.lock /app/Gemfile.lock RUN bundle install COPY . /app
docker-compose.yml
version: '3' services: web: build: . command: bundle exec rails s -p 3000 -b '0.0.0.0' volumes: - .:/app ports: - 3000:3000 depends_on: - db tty: true stdin_open: true db: image: mysql:5.7 volumes: - db-volume:/var/lib/mysql environment: MYSQL_ROOT_PASSWORD: password volumes: db-volume:
で
コマンドライン
docker-compose run web rails new --force --databese=mysql
docker-compose build
docker-compose up -d
docker-compose run web bundle exec rake db:create
としました。
その後、bootstarap 導入のため、
Gemfile

として再び
docker-compose build
としましたが、
docker-compose ps

となり、コンテナが起動しません。
docker-compose logs

となって、冒頭mini_racerのインストールに失敗している気がします。
お助けいただけると助かります。

gcc などが古いとこのようなことが起きるらしい回答を見つけました
Ruby - rails: request specがローカルでは通るのにcircle ciで落ちる｜teratail
何かの教則本を参考にプログラミングしていますでしょうか？
ベースイメージの ruby のバージョンがかなり古いようです:
dockerfile
1FROM ruby:2.3.6
回答時点では最新は 2.7.1 です
ruby - Docker Hub
可能であれば、最新版でやってみるとよいかもしれません
追記
Dockerfileあるいはdocker-compose.ymlに何かを書き足す、
ということでしょうか？
Dockerfile の FROM 命令のバージョンを変更します:
dockerfile
1FROM ruby:2.7.1
そして再度ビルドします:
console
1docker-compose build
