+If you prefer to build the image from source instead of fetching it, first ensure that your `$HOME/.m2/settings.xml` has a [personal access token](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens) that can read public repositories associated to the `github-playground-micronaut` server.

+The `settings.xml` file could look like this:

 Should you need to customise the port that `nginx` runs on, you can do so through the `PORT` environment variable (as required by Google Cloud Build):
 
 ```shell

 Your front-end folder should contain an `index.html` file. A minimal alternative front-end that you can use as a starting point for developing your custom front-end is available in the `miniground` folder of [this repository](miniground).
