gcloud beta functions command says "Invalid choice functions"

Question

I'm following the google cloud functions tutorial here: https://cloud.google.com/functions/docs/quickstart

I install google-cloud-sdk and source both path.bash.inc and completion.bash.inc.

The gsutil command step works and creates the storage bucket.

When I run gcloud beta functions deploy helloWorld --stage-bucket [BUCKET_NAME] --trigger-topic hello_world replacing with my [BUCKET_NAME] I get usage help and the following error:

``` ERROR: (gcloud.beta) Invalid choice: 'functions'.

Valid choices are [app, auth, bigtable, compute, config, container, dataflow, dataproc, debug, deployment-manager, emulators, error-reporting, iam, init, logging, ml, organizations, projects, pubsub, service-management, source, sql, test]. ```

I'm not sure how the gcloud command works, but I can see the functions directory in the lib/surface/ directory of the google-cloud-sdk.

Why does gcloud beta functions not work? How can I make it work?

Answer 1

Make sure you have the latest cloud SDK installed.

I got the same error and it seems I had version 137 while the latest is 152.

After running gcloud components update it was solved.

The functions are in subscription-only beta phase right now. From Quickstart:
