Generating the test rails app

It may be easiest to build locally and run to generate the rails app with the correct version.

test-app is a basic generated rails app to validate the container and dependencies.

gem install rails -v '5.2.8.1' # version is specific to a version test for the ruby version. You should be able to run others if the ruby version is supported.

rails new test-app generate a test app cd test-app bundle exec rails g scaffold hello generate a full resource and migrations bundle exec rails db:migrate RAILS_ENV=test migrate db

cd test-app
bundle exec rails test

Running the test app

./run.sh

cd test-app
rails db:migrate RAILS_ENV=development
rails s -b 0.0.0.0
