NAME: gcloud compute target-instances update - update a Compute Engine target instance
SYNOPSIS: gcloud compute target-instances update NAME [--security-policy=SECURITY_POLICY] [--security-policy-region=SECURITY_POLICY_REGION] [--zone=ZONE] [GCLOUD_WIDE_FLAG …]
DESCRIPTION: gcloud compute target-instances update updates a Compute Engine target instance.
EXAMPLES: To update the security policy run this:
gcloud compute target-instances update TARGET_INSTANCE --security-policy='my-policy'
POSITIONAL ARGUMENTS: NAME

Name of the target instance to update.
FLAGS: --security-policy=SECURITY_POLICY

The security policy that will be set for this target instance. To remove the policy from this target instance set the policy to an empty string.

--security-policy-region=SECURITY_POLICY_REGION

Region of the security policy to operate on. Overrides the default compute/region property value for this command invocation.

--zone=ZONE

Zone of the target instance 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.
