🛤Rails7.1

[yonta]

Rails7.1が出てるからアップグレードしていく！

動機

• Rails 7.1のリリース
• dependabotがRailsアップデートしろって
  • https://github.com/momocus/sakazuki/pull/699
  • Diif見ると、バージョン維持の=が消されて、今後勝手に8系に上がりうるのでこのままマージするのもちょっと

7.1ってどうなの

気になったやつ抜粋 https://rubyonrails.org/2023/10/5/Rails-7-1-0-has-been-released

• デプロイ用のDockerfileが生成される
  • マルチビルドやキャッシュ削除頑張ってるdockerfileが生成できるらしい
  • rails newしてみてどんなdockerfileができるのか見てみたい
• 認証サポートの追加
  • bycriptとdeviseいれてるし関係なさそう
• ActiveRecordの非同期クエリが追加
  • 今後、統計機能やるときに使えそう
  • 統計計算結果をキャッシュしようかなと思ってたけど、そういう必要がなくなるかも
• JSランタイムとしてBunをサポート
  • node.jsに代わる新たなランタイム
  • node.js + Yarn + esbuild => Bunへと移行できる？
  • https://kinsta.com/jp/blog/bun-sh/
  • ~あれ？Denoは？~

Dockerfileは下記テンプレからジェネレートされる railties/lib/rails/generators/rails/app/templates/Dockerfile.tt

rails newコマンドでこんなDockerfileがセットでできる

# syntax = docker/dockerfile:1

# Make sure RUBY_VERSION matches the Ruby version in .ruby-version and Gemfile
ARG RUBY_VERSION=3.3.0
FROM registry.docker.com/library/ruby:$RUBY_VERSION-slim as base

# Rails app lives here
WORKDIR /rails

# Set production environment
ENV RAILS_ENV="production" \
    BUNDLE_DEPLOYMENT="1" \
    BUNDLE_PATH="/usr/local/bundle" \
    BUNDLE_WITHOUT="development"

# Throw-away build stage to reduce size of final image
FROM base as build

# Install packages needed to build gems
RUN apt-get update -qq && \
    apt-get install --no-install-recommends -y build-essential git libvips pkg-config

# Install application gems
COPY Gemfile Gemfile.lock ./
RUN bundle install && \
    rm -rf ~/.bundle/ "${BUNDLE_PATH}"/ruby/*/cache "${BUNDLE_PATH}"/ruby/*/bundler/gems/*/.git && \
    bundle exec bootsnap precompile --gemfile

# Copy application code

より我々の環境に近いrails newを叩いてみた

• $ rails new app71 --asset-pipeline=propshuft --database=postgresql --javascript=esbuild --css=bootstrap

マルチステージビルドが参考になる。 このままprod用dockerイメージの作成に使えそうなくらいできが良い。

.dockerignore クレデンシャルのignore、大事ね。

# See https://docs.docker.com/engine/reference/builder/#dockerignore-file for more about ignoring files.

# Ignore git directory.
/.git/

# Ignore bundler config.
/.bundle

# Ignore all environment files (except templates).
/.env*
!/.env*.erb

# Ignore all default key files.
/config/master.key
/config/credentials/*.key

# Ignore all logfiles and tempfiles.
/log/*
/tmp/*
!/log/.keep
!/tmp/.keep

# Ignore pidfiles, but keep the directory.
/tmp/pids/*
!/tmp/pids/.keep

# Ignore storage (uploaded files in development and any SQLite databases).
/storage/*
!/storage/.keep
/tmp/storage/*
!/tmp/storage/.keep

# Ignore assets.
/node_modules/
/app/assets/builds/*
!/app/assets/builds/.keep
/public/assets

とりあえずprod環境dockerイメージを配る予定はない。 作っても、Cloudinaryでしか動かない。 配るならCloudinaryだけでなく、prod環境でローカル保存も作らないとな気がする。 やっぱdockerイメージで試しにさくっと動かす目的なら、PostgreSQLイメージとSAKAZUKIイメージでサクッと動いてほしい。 Cloudinaryの登録がいります、では敷居が高い。

ので、これをレポジトリには入れないでおこう。
