Heroku is a cloud service provider and software development platform which facilitates fast and effective building, deploying and scaling of web applications. It offers you a ready-to-use environment that allows you to deploy your code fast.
Some of the notable benefits of Heroku include:
- Users can get started with the free tier of Heroku
- Let developers concentrate on coding and not server management
- Integrates with familiar developer workflows
- Enhance the productivity of cloud app development teams
- Helps your development, QA, and business stakeholders create a unified dashboard
- Support for Modern Open Source Languages
Step 1. Create Redis Enterprise Cloud
Create your free Redis Enterprise Cloud account by visiting this link
For a limited time, use TIGER200 to get $200 credits on Redis Enterprise Cloud and try all the advanced capabilities!
Follow this link to create a Redis Enterprise Cloud subscription and database. Once you create the database, you will be provisioned with a unique database endpoint URL, port and password. Save these 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 Enterprise 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_ENDPOINT_URI and REDIS_PASSWORD under the Config Vars. Refer to Step 1 for the correct values to use.
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
