- DESCRIPTION
-
(BETA)
gcloud beta compute instance-groups managed rolling-action start-update
updates instances in a managed instance group, according to the given versions and the given update policy.An instance template version can be either a global or regional resource.
- EXAMPLES
-
Running:
gcloud beta compute instance-groups managed rolling-action start-update example-managed-instance-group \ --version='template=example-global-instance-template'
Sets the group's instance template version to a global instance template resource 'example-global-instance-template'.
To use a regional instance template, specify the full or partial URL of the template.
Running:
gcloud beta compute instance-groups managed rolling-action start-update example-managed-instance-group \ --version='template=projects/example-project/regions/us-central1/instanceTemplates/example-regional-instance-template'
Sets the group's instance template version to a regional instance template resource 'example-regional-instance-template'.
- POSITIONAL ARGUMENTS
-
NAME
- Name of the managed instance group to operate on.
- REQUIRED FLAGS
-
--version
=[template
=TEMPLATE
,[name
=NAME
],…]- Original instance template resource to be used. Each version has the following format: template=TEMPLATE,[name=NAME]
- COMMONLY USED FLAGS
-
--canary-version
=[template
=TEMPLATE
,target-size
=FIXED_OR_PERCENT
,[name
=NAME
],…]- New instance template resource to be used. Each version has the following format: template=TEMPLATE,target-size=FIXED_OR_PERCENT,[name=NAME]
--type
=TYPE
; default="proactive"-
Desired update type.
TYPE
must be one of:opportunistic
- Do not proactively replace VMs. Create new VMs and delete old ones on resizes of the group and when you target specific VMs to be updated or recreated.
proactive
- Replace instances proactively.
- OTHER FLAGS
-
--force
- If set, accepts any original or new version configurations without validation.
--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.
- 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.
--min-ready
=MIN_READY
-
Minimum time for which a newly created instance should be ready to be considered
available. For example
10s
for 10 seconds. See $ gcloud topic datetimes for information on duration formats. --minimal-action
=MINIMAL_ACTION
-
Use this flag to minimize disruption as much as possible or to apply a more
disruptive action than is strictly necessary. The MIG performs at least this
action on each instance while updating. If the update requires a more disruptive
action than the one specified here, then the more disruptive action is
performed. If you omit this flag, the update uses the
value from the MIG's update policy, unless it is not set in which case the default isminimal-action
.replace
MINIMAL_ACTION
must be one of:refresh
- Apply the new configuration without stopping VMs, if possible. For example, use ``refresh`` to apply changes that only affect metadata or additional disks.
restart
- Apply the new configuration without replacing VMs, if possible. For example, stopping VMs and starting them again is sufficient to apply changes to machine type.
replace
- Replace old VMs according to the --replacement-method flag.
--most-disruptive-allowed-action
=MOST_DISRUPTIVE_ALLOWED_ACTION
-
Use this flag to prevent an update if it requires more disruption than you can
afford. At most, the MIG performs the specified action on each instance while
updating. If the update requires a more disruptive action than the one specified
here, then the update fails and no changes are made. If you omit this flag, the
update uses the
value from the MIG's update policy, unless it is not set in which case the default ismost-disruptive-allowed-action
.replace
MOST_DISRUPTIVE_ALLOWED_ACTION
must be one of:refresh
- Apply the new configuration without stopping VMs, if possible. For example, use ``refresh`` to apply changes that only affect metadata or additional disks.
restart
- Apply the new configuration without replacing VMs, if possible. For example, stopping VMs and starting them again is sufficient to apply changes to machine type.
replace
- Replace old VMs according to the --replacement-method flag.
--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.
