I've been googling for a solution for some time and tried a couple of ways to solve this. In short: I used the sample from https://cloud.google.com/appengine/docs/python/googlecloudstorageclient/getstarted to create my own uploader, but it dies on the error, mentioned here: No api proxy found for service "app_identity_service" when running GAE script So, from what I understand, the script needs to be uploaded to google app engine and run from there using App Engine console. But even if it's possible, how do I automate it ?
Or maybe there are other solutions I'm missing. I looked through appcfg.pya but didn't find such an option as well.
