Long story short:
gcloud app deploy is going to be the preferred path for deployments going forward, and is currently supported. You'll have about a year after we declare deprecation to transition.- Before we deprecate
appcfg.py, we'll have a full migration guide with all of the changes. We don't want full backwards compatibility, because we're seizing this chance to fix some warts with the old tooling.
- You can run
gcloud app deploy cron.yaml and so on to deploy the alternate YAML files.
- Again, we're planning on writing a migration guide before we want to force you over to the new tooling.
So I think you can punt on this until we've officially deprecated the appcfg tooling–gcloud app is really meant for brave explorers who want the newest and shiniest for now.
