Understanding the Guestbook application
In this chapter, you will create a Helm chart to deploy the Guestbook tutorial application provided by the Kubernetes community. This application is introduced in the Kubernetes documentation at the following page: https://kubernetes.io/docs/tutorials/stateless-application/guestbook/
The Guestbook application is a simple PHP: Hypertext Preprocessor (PHP) frontend designed to persist messages to a Redis backend. The frontend consists of a dialog box and a Submit button, as illustrated in the following screenshot:
- Type a message in the Messages dialog box.
- Click the Submit button.
- When the Submit button is clicked, the message will be saved to a Redis database.
