gcloud alpha memcache instances apply-software-update - apply software update to nodes in a Memorystore Memcached instance

gcloud alpha memcache instances apply-software-update(INSTANCE :--region=REGION)(--apply-all    |--node-ids=[NODE_IDS,…])[--async][GCLOUD_WIDE_FLAG …]

To check if a Memcache instance and its nodes have a new software updateavailable, run:

gcloudbetamemcacheinstancesdescribemy-memcache-instance--format="table(updateAvailable.yesno(),memcacheNodes:format='table(nodeId,updateAvailable.yesno())')"--region=us-central1

Applying a software update to a node causes a full cache flush on that node.

gcloudalphamemcacheinstancesapply-software-updatemy-memcache-instance--node-ids=node-1,node-2--region=us-central1

To apply software update to all nodes of a Memcached instance named'my-memcache-instance' in region 'us-central1', run:

gcloudalphamemcacheinstancesapply-software-updatemy-memcache-instance--apply-all--region=us-central1

Instance resource - Arguments and flags that specify the Memcached instance onwhich to apply software update. The arguments in this group can be used tospecify the attributes of this resource. (NOTE) Some attributes are not givenarguments in this group but can 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:

--apply-all

Apply the software update onto all nodes.

--node-ids=[NODE_IDS,…]

Nodes on which to apply the software update.

--async

Return immediately, without waiting for the operation in progress to complete.
