Commit your site's static files to a directory in your project repository, then point your app's yaml configuration to it by defining a web.locations key in your .platform.app.yaml file. The root key should contain the name of this directory, for example, if your files are located in the "public" directory, add this to your app configuration:
web:
locations:
'/':
root: 'public'You can define where requests to the root domain are sent. Do this by adding an index key which contains a list of file names:
web:
locations:
'/':
...
index: ['index.html']
