SYNOPSIS
gcloud compute reservations update RESERVATION [--add-share-with=PROJECT,[PROJECT,…]] [--add-share-with-project=PROJECT,[PROJECT,…]] [--early-access-maintenance=EARLY_ACCESS_MAINTENANCE] [--[no-]enable-emergent-maintenance] [--remove-share-with=PROJECT,[PROJECT,…]] [--reservation-sharing-policy=RESERVATION_SHARING_POLICY] [--scheduling-type=SCHEDULING_TYPE] [--vm-count=VM_COUNT] [--zone=ZONE] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
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 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 compute reservations update my-reservation --remove-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 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,…]
If this reservation is shared (--share-setting is projects), then specify a comma-separated list of projects to share the reservation with. You must list the projects using project IDs or project numbers.
--add-share-with-project=PROJECT,[PROJECT,…]
Specify a comma-separated list of projects to share the reservation with. You must list the projects using project IDs or project numbers.
--early-access-maintenance=EARLY_ACCESS_MAINTENANCE
Enable this feature to receive quarterly updates and new features for your reservation earlier than the standard schedule.. EARLY_ACCESS_MAINTENANCE must be one of:
NO_EARLY_ACCESS
Standard maintenance schedule. The reservation doesn't have early access maintenance.
WAVE1
Provides the earliest available notification and maintenance.
WAVE2
Provides notification and maintenance after WAVE1, but before the standard maintenance schedule.
--[no-]enable-emergent-maintenance
Enables the reservation to receive notifications when urgent maintenance for a GPU VM starts after the VM encounters a host error. Use --enable-emergent-maintenance to enable and --no-enable-emergent-maintenance to disable.
--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.
--scheduling-type=SCHEDULING_TYPE
How Compute Engine schedules maintenance events for your reserved hosts. SCHEDULING_TYPE must be one of:
GROUPED
In GROUPED mode, maintenance is synchronized across all your VMs.
INDEPENDENT
In INDEPENDENT mode, your VMs have different, unsynchronized maintenance schedules.
--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.
GCLOUD WIDE FLAGS
