NAME
gcloud memcache instances update - update a Memorystore Memcached instance
SYNOPSIS
gcloud memcache instances update (INSTANCE : --region=REGION) (--parameters=KEY=VALUE     | --display-name=DISPLAY_NAME --labels=[KEY=VALUE,…] --node-count=NODE_COUNT --maintenance-window-any     | --maintenance-window-day=MAINTENANCE_WINDOW_DAY --maintenance-window-duration=MAINTENANCE_WINDOW_DURATION --maintenance-window-start-time=MAINTENANCE_WINDOW_START_TIME) [--async] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
Update a Memcached instance with one or more of the following actions:
  • 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 same call. All other update actions can be combined in the same call.

EXAMPLES
To scale a Memcached instance named 'my-memcache-instance' in region 'us-central1' to have 3 nodes, run: 
gcloud memcache instances update my-memcache-instance --node-count=3 --region=us-central1

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

gcloud memcache instances update my-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: 

gcloud memcache instances update my-memcache-instance --display-name="Foo Cache Service" --labels="env=test,service=foo"
POSITIONAL ARGUMENTS

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

--region=REGION
The name of the Memcached region of the instance. Overrides the default memcache/region property value for this command invocation. To set the region attribute:
  • provide the argument instance on the command line with a fully specified name;
  • provide the argument --region on the command line;
  • set the property memcache/region.
