Add Heroku hosting to our rails application

We are going to use Heroku to host our rails application.

Create a Heroku account

Before continuing ensure that you have a Heroku account.

Install the Client (MAC)

brew tap heroku/brew && brew install heroku

Install the Client (Linux Subsystem for Windows)

curl | sh

Adding heroku to our application

From the main directory of your rails application

echo "On the next line type the name of your application"
echo ""
echo "It must *NOT* have spaces in the name, use dashes for separation"
echo ""
echo "Example:  my-cool-app"
echo ""
echo -n "Type the name of the application: " && read name
heroku create "${name}"

Push once to heroku

Heroku is going to manage our application via git -- We will use git push to send our code to Heroku just like we do for storing it on GitHub for safekeeping. However, we need to tell git push that we aren't pushing to the default of GitHub, but to Heroku.

We do this with the following command:

git push heroku master

Add nodejs buildpack if we have a built in React application

NOTE Skip this step if you do not have a React application embedded in your Rails app

heroku buildpacks:add --index 1 heroku/nodejs
git commit --allow-empty -m "Adding nodejs buildpack to Heroku"
git push heroku master

Ensure our database is migrated in production

Every time we push code to Heroku that has new migrations we must run these migrations before using our application

We do that with the command

heroku run rails db:migrate

Ensure our seed/sample data is in production (if we want)

If you want your seed/sample data in production you can run the same rails command in Heroku that you ran locally.

For instance if you created a task named sampledata:load and you used rails sampledata:load in development, then in production you can run heroku run rails sampledata:load
