DESCRIPTION
Sets the IAM policy for the given reservation sub-block as defined in a JSON or YAML file.
EXAMPLES
To set the IAM policy on a reservation sub-block in reservation my-reservation in zone us-central1-a with block name my-block and sub-block name my-sub-block using a policy file policy.json, run: 
gcloud compute reservations sub-blocks set-iam-policy my-reservation policy.json --zone=us-central1-a --block-name=my-block --sub-block-name=my-sub-block
POSITIONAL ARGUMENTS
RESERVATION
Name of the reservation to set-iam-policy.
POLICY_FILE
Path to a local JSON or YAML formatted file containing a valid policy. The output of the get-iam-policy command is a valid file, as is any JSON or YAML file conforming to the structure of a Policy.
REQUIRED FLAGS
--block-name=BLOCK_NAME
The name of the reservation block.
--sub-block-name=SUB_BLOCK_NAME
The name of the reservation sub block.
OPTIONAL FLAGS
--zone=ZONE
Zone of the reservation to set-iam-policy. 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.
