gcloud compute instance-groups managed resume-instances

NAME
gcloud compute instance-groups managed resume-instances - resume the suspended instances in a managed instance group
SYNOPSIS
gcloud compute instance-groups managed resume-instances NAME --instances=INSTANCE,[INSTANCE,…] [--region=REGION     | --zone=ZONE] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
gcloud compute instance-groups managed resume-instances resumes one or more instances from a managed instance group, thereby increasing the targetSize and reducing the targetSuspendedSize of the group. The command returns the operation status per instance, which might be FAIL, SUCCESS, or MEMBER_NOT_FOUND. MEMBER_NOT_FOUND is returned only for regional groups when the gcloud command-line tool wasn't able to resolve the zone from the instance name.
EXAMPLES
To resume an instance from a managed instance group in the us-central1-a zone, run: 
gcloud compute instance-groups managed resume-instances example-managed-instance-group --zone=us-central1-a --instances=example-instance
