NAME: gcloud beta compute instance-groups managed all-instances-config update - update the all-instances configuration of a managed instance group
SYNOPSIS: gcloud beta compute instance-groups managed all-instances-config update NAME [--labels=KEY=VALUE,[KEY=VALUE,…]] [--metadata=KEY=VALUE,[KEY=VALUE,…]] [--region=REGION | --zone=ZONE] [GCLOUD_WIDE_FLAG …]
DESCRIPTION: (BETA) gcloud beta compute instance-groups managed all-instances-config update updates the group's all-instances configuration and applies it only to new instances that are added to the group.
To apply a revised all-instances configuration to existing instances in the group, use one of the following methods:

Update instances using the update-instances command.

Recreate instances using the recreate-instances command.

Use the rolling-action start-update command.

Use the API to set the group's updatePolicy.type to PROACTIVE.
EXAMPLES: To update an all-instances configuration in order to override the group's instance template for a label with the key label-key and metadata with the key metadata-key in group my-group, run:
gcloud beta compute instance-groups managed all-instances-config update my-group --metadata=metadata-key=metadata-override-value --labels=qlabel-key=label-override-value
