gcloud compute instance-groups managed rolling-action replace - replaces instances in a managed instance group
gcloud compute instance-groups managed rolling-action replace NAME [--max-surge=MAX_SURGE] [--max-unavailable=MAX_UNAVAILABLE] [--replacement-method=REPLACEMENT_METHOD] [--region=REGION | --zone=ZONE] [GCLOUD_WIDE_FLAG ...]
Deletes the existing instance and creates a new instance from the target template. The Updater creates a brand new instance with all new instance properties, such as new internal and external IP addresses.
- NAME
Name of the managed instance group to operate on.
- --max-surge=MAX_SURGE
Maximum additional number of instances that can be created during the update process. This can be a fixed number (e.g. 5) or a percentage of size to the managed instance group (e.g. 10%). Defaults to 0 if the managed instance group has stateful configuration, or to the number of zones in which it operates otherwise.
- --max-unavailable=MAX_UNAVAILABLE
Maximum number of instances that can be unavailable during the update process. This can be a fixed number (e.g. 5) or a percentage of size to the managed instance group (e.g. 10%). Defaults to the number of zones in which the managed instance group operates.
- --replacement-method=REPLACEMENT_METHOD
Type of replacement method. Specifies what action will be taken to update instances. Defaults to ``recreate`` if the managed instance group has stateful configuration, or to ``substitute`` otherwise. REPLACEMENT_METHOD must be one of:
- recreate
Recreate instances and preserve the instance names. The instance IDs and creation timestamps might change.
- substitute
Delete old instances and create instances with new names.
- At most one of these can be specified:
- --region=REGION
Region of the managed instance group to operate on. If not specified, you might be prompted to select a region (interactive mode only).
A list of regions can be fetched by running:
$ gcloud compute regions list
Overrides the default compute/region property value for this command invocation.
- --zone=ZONE
Zone of the managed instance group to operate on. If not specified, you might be prompted to select a zone (interactive mode only).
A list of zones can be fetched by running:
$ gcloud compute zones list
Overrides the default compute/zone property value for this command invocation.
