Step 1. Create Redis Cloud
Create your free Redis Cloud account. Follow this link to create Redis Cloud subscription and database as shown below:
Save the database endpoint URL and password for future reference.
Step 2. Create a Heroku account
If you are using Heroku for the first time, create your new Heroku account through this link
Step 3. Install Heroku CLI on your system
brew install heroku
Step 4. Login to Heroku
heroku: Press any key to open up the browser to login or q to exit:
Opening browser to https://cli-auth.heroku.com/auth/cli/browser/XXXXXXXXXXA
Logging in... done
Logged in as your_email_address
Step 5. Connect your application to Redis Cloud
For this demonstration, we will be using a Sample Rate Limiting application
Clone the repository
git clone https://github.com/redis-developer/basic-rate-limiting-demo-java
Creating app... done, ⬢ hidden-woodland-03996
https://hidden-woodland-03996.herokuapp.com/ | https://git.heroku.com/hidden-woodland-03996.git
Step 6. Setting up environment variables
Go to Heroku dashboard, click "Settings" and set
REDIS_PASSWORD under the Config Vars.
Refer to Step 1 for reference.
You now have a functioning Git repository that contains a simple application as well as a package.json file, which is used by Node’s dependency manager.
Step 7. Deploy your code
Heroku generates a random name (in this case hidden-woodland-03996) for your app, or you can pass a parameter to specify your own app name. Now deploy your code:
$ git push heroku

* [new branch] master -> master
Step 8. Accessing the application
Open https://hidden-woodland-03996.herokuapp.com/ to see your application
