EXAMPLES

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,…]
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.
--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.
