Automate gcloud components update

Question

How can I update the gcloud components programmatically within a shell script?

Calling gcloud components update requires an user entry, e.g.:

$ gcloud components update

The following components will be installed:
--------------------------------------------
| kubectl (Linux, x86_64) | 1.0.1 | 4.5 MB |
--------------------------------------------

Do you want to continue (Y/n)? 

I can't find an argument for gcloud to enforce the update.

You're looking for the --quiet flag.

From gcloud --help:

 --quiet, -q
    Disable all interactive prompts when running gcloud commands. If input
    is required, defaults will be used, or an error will be raised.

This is generally a flag you'll want for non-interactive contexts.

You may also set the CLOUDSDK_CORE_DISABLE_PROMPTS environment variable to a non-empty value:

export CLOUDSDK_CORE_DISABLE_PROMPTS=1
gcloud components update # This works for all gcloud commands
