Error deploying Python app to App Engine Flexible Environment

[Trish Whetzel]

I went through the tutorial Quickstart for Python in the App Engine Flexible Environment to deploy the sample Python app and was able to get that to work. I am now trying to deploy my own app and am getting the error:
Post https://us.gcr.io/v2/flexible-vm-python/appengine/default.20160603t094107/blobs/uploads/

: token auth attempt for registry: https://us.gcr.io/v2/token?account=_token&scope=repository%3Aflexible-vm-python%2Fappengine%2Fdefault.20160603t094107%3Apush%2Cpull&service=us.gcr.io request failed with status: 400 Bad Request

ERROR: (gcloud.preview.app.deploy) Error Response: [2] Build failed; check build logs for details

I do have billing enabled for this project. Ideas on how to resolve and/or where to look for the build logs for more details?

Also, how do I change what App Engine project it is deployed to? For example, 'flexible-vm-python' is the project I used for the Hello World sample. The project for this app is 'flexible-vm-api-profiler'.

I see now, I needed to run gcloud init again to configure deployment of the new app.

Glad to hear you were able to sort it out. Alternatively, you can also use 'gcloud config set project <project>' to directly switch the project.

Some other useful commands are 'gcloud config set account <account>' to switch to another credential you have saved, and 'gcloud auth login' if you need to sign in to another Google account.
