$ heroku login

# remember heroku instance is wellplayed with platform below
$ bundle lock --add-platform x86_64-linux --add-platform ruby

# remember postgres is wellplayed too
$ rails new app --database=postgresql

Assume you push already

$ heroku create
$ git push heroku main

# usually they created an associated database instance, you just need to come to `config/database.yml` 
# under production: add url: ENV['DATABASE_URL'], else (in case something is wierd)
$ heroku addons:create heroku-postgresql:hobby-dev
$ heroku addons
$ heroku pg:info

# again
$ git push
$ git push heroku main

# FOR RUNNING RAKE
$ heroku run rails db:prepare
$ heroku run rails db:seed
$ heroku run rake load_hotel_data_from_sources

# CONTAINER (docker is BELOW)
# https://devcenter.heroku.com/articles/container-registry-and-runtime

# If you are migrating from heroku common stack to container stack
# heroku stack:set container
# else heroku stack:set heroku-20

$ heroku container:login
