   Compose pulls a Redis image, builds an image for your code, and starts the
   services you defined. In this case, the code is statically copied into the image at build time.

2. Enter `http://localhost:8000/` in a browser to see the application running.

   If this doesn't resolve, you can also try `http://127.0.0.1:8000`.

   You should see a message in your browser saying:

   ```text
   Hello World! I have been seen 1 times.
   ```



3. Refresh the page.

   The number should increment.

   ```text
   Hello World! I have been seen 2 times.
   ```

Title: Accessing the Application and Verifying Functionality

Summary

After building and running the application with Docker Compose, it can be accessed through a web browser using `http://localhost:8000/` or `http://127.0.0.1:8000`. The initial view displays a 'Hello World!' message along with a counter. Refreshing the page increments the counter, confirming the application's basic functionality and interaction with the Redis service.
