-Modify Dockerfile as you want to build yor app.
-For example, to build rails change last line to 
+`docker run -it 200de23ba865 bash`
+`./a.out server -e production`
+or
+`docker run -p 3001:3000 -it 200de23ba865 ./a.out server -e production -p 3000`
 
-`RUN rubyc bin/rails`
+And from you host machine: http://localhost:3001/
+
+This example rails app generate from rails v5.2 template.
+With applying next changes:
+1) add to Gemfile `gem 'nokogiri', '~> 1.10', '>= 1.10.1'` to test building app with native extensions
+2) add to Gemfile `gem 'therubyracer'` to working assets compiling(node runtime)
+3) add to Gemfile `gem 'tzinfo-data'` to internal work with data
+4) comment Gemfile `gem 'bootsnap', '>= 1.1.0', require: false`
+5) `config/boot.rb` comment `require 'bootsnap/setup'`
+6) `config/environments/production.rb` change cache store config `config.cache_store = :memory_store, { size: 64.megabytes }`
+
+! Note: `rubyc` build readonly file system that's why you can not:
+1) run app in development env with watching files, but you can config development env without watching files - so run app with `production` env
+2) use rails cache with file_store in local Rails.root folder - you must use another folder such as `/tmp/my_cache/` or memory cache
+3) compile assets on the fly - you must compile assets before packing app
