• Scale up or down the number of nodes in the instance.
• Stage an update to instance configuration parameters.
• Update the instance metadata (display name, labels).

Updating parameters cannot be combined with any other update actions in the samecall. All other update actions can be combined in the same call.

gcloudalphamemcacheinstancesupdatemy-memcache-instance--node-count=3--region=us-central1

To stage an update to the parameters 'protocol' and 'track-sizes' for aMemcached instance named 'my-memcache-instance' in region 'us-central1', run:

gcloudalphamemcacheinstancesupdatemy-memcache-instance--parameters="protocol=ascii,track-sizes=true"--region=us-central1

To update a Memcached instance named 'my-memcache-instance' in region'us-central1' to have the display name "Foo Cache Service" and the labels 'env'and 'service', run:

gcloudalphamemcacheinstancesupdatemy-memcache-instance--display-name="Foo Cache Service"--labels="env=test,service=foo"

Instance resource - Arguments and flags that specify the Memcached instance toupdate. The arguments in this group can be used to specify the attributes ofthis resource. (NOTE) Some attributes are not given arguments in this group butcan be set in other ways.

To set theproject attribute:

• provide the argumentinstance on the command line with a fullyspecified name;
• provide the argument--project on the command line;
• set the propertycore/project.

This must be specified.

INSTANCE

ID of the instance or fully qualified identifier for the instance.

To set theinstance attribute:

• provide the argumentinstance on the command line.

This positional argument must be specified if any of the other arguments in thisgroup are specified.

--region=REGION

The name of the Memcached region of the instance. Overrides the defaultmemcache/region property value for this command invocation.To set theregion attribute:

• provide the argumentinstance on the command line with a fullyspecified name;
• provide the argument--region on the command line;
• set the propertymemcache/region.

Exactly one of these must be specified:
