Put Your App Online With DigitalOcean App Platform
Created by Colin Alston
Change the production database
Locally your app uses SQLite as the database to store your ideas. It’s easier to use another database on DigitalOcean deploys. To deploy with DigitalOcean we’ll change the database in production to use PostgreSQL.
Install the pg gem
Gemfile file in your Text Editor and change the following line:
into these lines:
Next, run the command below to setup the new database gem:
Update the database configuration
Up next, you’ll need to change the database configuration for the production environment.
Explain what the different Rails environments are. What is “production”?
config/database.yml file in your Text Editor. Change the following lines in the file:
to these lines:
Save the changes in Git by creating a new commit. We’ll need to update our app in Git to deploy these changes.
Create an account
Head to https://www.digitalocean.com/go/app-platform and sign up for the 60 day free trial.
Sign up using Github to link your account
You will need a credit card but will receive $200 to start with if this is your first time using DigitalOcean.
Create an application
Deploy a web application to get started.
Choose “Deploy your web app” to add an existing GitHub repository
Authorize DigitalOcean to read your repositories
Select the repository for your application
Next to continue then
Edit Plan to ensure we use the appropriate resources. We will start with a Basic plan and the smallest container size which should be sufficient.
Continue through the next steps until the end. We should not need to change anything else.
Deploying our Rails application
Wait for the application to build, you can view realtime logs of the process while it happens.
If all went well you should see your application is available, however it still needs to be initialized and have a database added.
Create/Attach Database to connect a PostgreSQL database.
The application will automatically be configured with the database credentials
You can now head to the
Console to access your application container and setup the database.
rails db:migrate into the terminal and press Enter. You should see the database being setup with the Rails schema.
If all went well you should now be able to click on the
Live App button which links to the live server.
Your Rails app is now running in the cloud on DigitalOcean. You can push your changes to GitHub and they’ll show up automatically the live URL after some time. Share the URL to show off your app to your friends!
Keep an eye out when your free credits run out and delete the app if you no longer need it.
