commands have changed

[patflynn]

with the latest version of gcloud:
gcloud preview app setup-managed-vms
returns:
ERROR: (gcloud.preview.app) Invalid choice: 'setup-managed-vms'.

Also running:
gcloud preview app run .
returns:
ERROR: Directories are not supported [.]. You must provide explicit yaml files.
ERROR: (gcloud.preview.app.run) Errors occurred while parsing the App Engine app configuration.

running:
gcloud preview app run app.yaml, the command starts the server but I was unable to get it to connect:
ERROR 2015-04-29 15:22:55,492 instance.py:280] 500 Server Error: Internal Server Error ("Cannot start container 219bab0e2037f35a72c9c18edfb3fbeeaaac47ee21ed8dd08f3e043b3e8843b2: (exit status 1)")

Perhaps this is a problem with my docker configuration.

Running:
gcloud preview app deploy . causes the same error as the run command. running gcloud preview app run app.yaml causes the following error:

WARNING: The [version] field is specified in file [/usr/local/google/home/paflynn/hack/appengine-fluent-hello/app.yaml]. This field is not used by gcloud and should be removed.
ERROR: The version [1] declared in [/usr/local/google/home/paflynn/hack/appengine-fluent-hello/app.yaml] does not match the current gcloud version [20150429t112434].
ERROR: (gcloud.preview.app.deploy) Errors occurred while parsing the App Engine app configuration.

I removed the 'version' element from the app.yaml and then deploy was successful according to the command-line. Although the version was never updated to be the default, perhaps this is a new feature of app engine.
