gcloud compute instance-groups managed delete-instances is used to deletes one or more instances from a managed instance group. Once the instances are deleted, the size of the group is automatically reduced to reflect the changes.
If you would like to keep the underlying virtual machines but still remove them from the managed instance group, use the abandon-instances command instead.
NAMEManaged instance group name.
--instances INSTANCE,[INSTANCE,...]Names of instances to delete.
--zone ZONEThe zone of the instance group manager to delete instances. If not specified, you will be prompted to select a zone.
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.
Run $ gcloud help for a description of flags available to all commands.
