For MacOS just use the [official app](https://docs.docker.com/engine/installation/mac/). - [`dip`](https://github.com/bibendi/dip) installed. You can install `dip` as Ruby gem: ```sh gem install dip ``` ## Provisioning When using Dip it could be done with a single command: ```sh dip provision ``` ## Running ```sh dip rails s ``` ## Developing with Dip ### Useful commands ```sh # run rails console dip rails c # run rails server with debugging capabilities (i.e., `debugger` would work) dip rails s # or run the while web app (with all the dependencies) dip up web # run migrations dip rails db:migrate # pass env variables into application dip VERSION=20100905201547 rails db:migrate:down # simply launch bash within app directory (with dependencies up) dip runner # execute an arbitrary command via Bash dip bash ls -al tmp/cache # Additional commands # update gems or packages dip bundle install <% if yarn_version %> dip yarn install <% end %> <% if postgres_version %> # run psql console dip psql <% end %> <% if redis_version %> # run Redis console dip redis-cli <% end %> # run tests <% if gemspecs.key?("rspec") %> # TIP: `dip rspec` is already auto prefixed with `RAILS_ENV=test` dip rspec spec/path/to/single/test.rb:23 <% else %> # TIP: `dip rails test` is already auto prefixed with `RAILS_ENV=test` dip rails test <% end %> # shutdown all containers dip down ``` ### Development flow Another way is to run `dip ` for every interaction. If you prefer this way and use ZSH, you can reduce the typing by integrating `dip` into your session: ```sh $ dip console | source /dev/stdin# no `dip` prefix is required anymore! $ rails c Loading development environment (Rails 7.0.1) pry> ``` CODE ], trim_mode: "<>").result(binding) todos = [ "📝 Important things to take care of:", " - Make sure you have `ENV[\"RAILS_ENV\"] = \"test\"` (not `ENV[\"RAILS_ENV\"] ||= \"test\"`) in your test helper." ] if database_url todos << " - Don't forget to add `url: ENV[\"DATABASE_URL\"]` to your database.yml" end if todos.any? say_status(:warn, todos.join("\n")) end say_status :info, "✅ You're ready to sail!
