hello_rails7_pg_redis

A template to create a rails7 dev container.

0. create a project from this template. for example try_rails7

1. In your dev container

   1. (optional) service start cron if you need crontab to work.
   2. Generate your rails project in the dev container. For example, the commands below will create a new Rails project using the Rails 7 default assets pipeline which is my favorite.

      gem install rails
      rails new . --force -d=postgresql

   3. fix config/database.yml by adding the host, username and password to the development section.

      ...
      development:
        <<: *default
        database: try_rails7_development
        host: <%= ENV.fetch("DB_HOST") { "db" } %>
        username: <%= ENV.fetch("DB_USERNAME") { "postgres" } %>
        password: <%= ENV.fetch("DB_PASSWORD") { "password" } %>
      ...

   4. run your app in the container.

      bundle exec rails s -p 3000 -b '0.0.0.0'

2. now, everything is ready.
