gcloud alpha compute reservations blocks describe

NAME: gcloud alpha compute reservations blocks describe - describe a Compute Engine image
SYNOPSIS: gcloud alpha compute reservations blocks describe RESERVATION --block-name=BLOCK_NAME [--zone=ZONE] [GCLOUD_WIDE_FLAG …]
DESCRIPTION: (ALPHA) Describe a Compute Engine image.
EXAMPLES: To describe a reservation block in reservation exr1 in my-zone with block name block1, run:
gcloud alpha compute reservations blocks describe exr1 --zone=my-zone --block-name=block1
POSITIONAL ARGUMENTS: RESERVATION

Name of the reservation to describe.
REQUIRED FLAGS: --block-name=BLOCK_NAME

The name of the reservation block.
OPTIONAL FLAGS: --zone=ZONE

Zone of the reservation to describe. If not specified and the compute/zone property isn't set, you might be prompted to select a zone (interactive mode only).
To avoid prompting when this flag is omitted, you can set the compute/zone property:
gcloud config set compute/zone ZONE

A list of zones can be fetched by running:
gcloud compute zones list

To unset the property, run:
gcloud config unset compute/zone

Alternatively, the zone can be stored in the environment variable CLOUDSDK_COMPUTE_ZONE.
GCLOUD WIDE FLAGS: These flags are available to all commands: --access-token-file, --account, --billing-project, --configuration, --flags-file, --flatten, --format, --help, --impersonate-service-account, --log-http, --project, --quiet, --trace-token, --user-output-enabled, --verbosity.
Run $ gcloud help for details.
NOTES: This command is currently in alpha and might change without notice. If this command fails with API permission errors despite specifying the correct project, you might be trying to access an API with an invitation-only early access allowlist.
