hello_rails7_pg_redis

A template to create a rails 7 dev container.

  • ruby 3.3
  • rails 7.1.3
  • postgres 14 + pgadmin4-8.5
  • redis latest + redisinsight
  • nodejs 18
  • (optional)rust

How to use

  1. create a repo from this template.

  2. clone the repo to your local

  3. start a dev container for your local repo.

    I'v tried 1. vscode, 2. neovim + nvim-dev-container. both are ok.

  4. In your dev container

    1. (optional) service start cron if you need crontab to work.

    2. Generate your rails project in the dev container.

      # importmaps + propshaft (my prefer) 
rails new . -a propshaft -d=postgresql

# or, one of the following
# importmaps + sprockets
rails new . -d=postgresql

# importmaps + sprockets + tailwind, https://techracho.bpsinc.jp/hachi8833/2022_02_17/115435
rails new . --css tailwind -d=postgresql

# importmaps + propshaft + tailwind
rails new . --css tailwind -a propshaft -d=postgresql

# (nodejs) esbuild + sprockets + tailwind(my prefer)
rails new . --javascript esbuild --css tailwind -d=postgresql

# (nodejs) esbuild + propshaft + bootstrap
rails new . --javascript esbuild --css bootstrap -a propshaft -d=postgresql

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

      ...
default: &default
   ...
   host: <%= ENV.fetch("POSTGRES_HOST") { "db" } %>
   username: <%= ENV.fetch("POSTGRES_USERNAME") { "postgres" } %>
   password: <%= ENV.fetch("POSTGRES_PASSWORD") { "password" } %>
...
      bundle exec rails db:create

    4. run your app in the container.

      ./bin/rails s

# OR in nodejs build mode
./bin/dev
