NAME: gcloud alpha compute reservations update - update Compute Engine reservations
SYNOPSIS: gcloud alpha compute reservations update RESERVATION [--add-share-with=PROJECT,[PROJECT,…]] [--remove-share-with=PROJECT,[PROJECT,…]] [--reservation-sharing-policy=RESERVATION_SHARING_POLICY] [--share-with=SHARE_WITH,[SHARE_WITH,…]] [--vm-count=VM_COUNT] [--zone=ZONE] [--delete-after-duration=DELETE_AFTER_DURATION | --delete-at-time=DELETE_AT_TIME | --disable-auto-delete] [GCLOUD_WIDE_FLAG …]
DESCRIPTION: (ALPHA) Update Compute Engine reservations.
EXAMPLES: To add project-1,project-2,project-3 to the list of projects that are shared with a Compute Engine reservation, my-reservation in zone: us-central1-a, run:
gcloud alpha compute reservations update my-reservation --add-share-with=project-1,project-2,project-3 --zone=us-central1-a

To remove project-1,project-2,project-3 from the list of projects that are shared with a Compute Engine reservation, my-reservation in zone: us-central1-a, run:
gcloud alpha compute reservations update my-reservation --remove-share-with=project-1,project-2,project-3 --zone=us-central1-a

To update the entire list of projects that are shared with a Compute Engine reservation, my-reservation in zone: us-central1-a, run:
gcloud alpha compute reservations update my-reservation --share-with=project-1,project-2,project-3 --zone=us-central1-a

To update the number of reserved VM instances to 500 for a Compute Engine reservation, my-reservation in zone: us-central1-a, run:
gcloud alpha compute reservations update my-reservation --zone=us-central1-a --vm-count=500
POSITIONAL ARGUMENTS: RESERVATION

Name of the reservation to update.
FLAGS: --add-share-with=PROJECT,[PROJECT,…]

A list of specific projects to add to the list of projects that this reservation is shared with. List must contain project IDs or project numbers.

--remove-share-with=PROJECT,[PROJECT,…]

A list of specific projects to remove from the list of projects that this reservation is shared with. List must contain project IDs or project numbers.

--reservation-sharing-policy=RESERVATION_SHARING_POLICY

The reservation sharing policy to use for this reservation. RESERVATION_SHARING_POLICY must be one of:

ALLOW_ALL

The reservation can be shared with Google Cloud services.

DISALLOW_ALL

The reservation won't be shared with Google Cloud services. If you omit this flag during creation, the default value is DISALLOW_ALL.

--share-with=SHARE_WITH,[SHARE_WITH,…]

If this reservation is shared (--share-setting is not local), provide a list of all of the specific projects that this reservation is shared with. List must contain project IDs or project numbers.

--vm-count=VM_COUNT

The number of VM instances that are allocated to this reservation. The value of this field must be an int in the range [1, 1000].

--zone=ZONE

Zone of the reservation to update. 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.

Manage auto-delete properties for reservations.
At most one of these can be specified:

--delete-after-duration=DELETE_AFTER_DURATION

Automatically deletes the reservations after a specified number of days, hours, minutes, or seconds from its creation. For example, specify 30m for 30 minutes, or 1d2h3m4s for 1 day, 2 hours, 3 minutes, and 4 seconds. For more information, see $ gcloud topic datetimes.

--delete-at-time=DELETE_AT_TIME

Automatically deletes the reservation at a specific time from its creation. The specified time must be an RFC3339 timestamp, which must be formatted as "YYYY-MM-DDTHH:MM:SSZ" where YYYY = year, MM = month, DD = day, HH = hours, MM = minutes, SS = seconds, and Z = time zone in Coordinated Universal Time (UTC). For example, specify 2021-11-20T07:00:00Z.

--disable-auto-delete

Disables the auto-delete setting for the reservation.
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. These variants are also available:
