I have a Golang application which is deployed to Google Cloud App Engine. This application uses some static files for security (.crt and .key files) and templating (.xml and .html) files. The application tries to read the files, but returns an error about not finding them.
I guess the files are not uploaded when I run gcloud app deploy and I think I have to add something to my app.deploy file, but I can't find anything in the documentation of App Engine.
I've read that making the files available using handlers and static-files will upload the necessary files to the App Engine system, but I don't want make my .crt and .key files publicly available.
