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

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

DESCRIPTION
    (BETA) Apply a software update to nodes in a Memcached instance to the
    latest available software version.

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

        $ gcloud beta memcache instances describe my-memcache-instance \
            --format="table(updateAvailable.yesno(),memcacheNodes:format='ta\
        ble(nodeId,updateAvailable.yesno())')" --region=us-central1

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

EXAMPLES
    To apply software update to nodes 'node-1' and 'node-2' of a Memcached
    instance named 'my-memcache-instance' in region 'us-central1', run:

        $ gcloud beta memcache instances apply-software-update \
            my-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:

        $ gcloud beta memcache instances apply-software-update \
            my-memcache-instance --apply-all --region=us-central1

POSITIONAL ARGUMENTS
     Instance resource - Arguments and flags that specify the Memcached
     instance on which to apply software update. The arguments in this group
     can be used to specify the attributes of this resource. (NOTE) Some
     attributes are not given arguments in this group but can be set in other
     ways.

     To set the project attribute:
      ◆ provide the argument instance on the command line with a fully
        specified name;
      ◆ provide the argument --project on the command line;
      ◆ set the property core/project.

     This must be specified.

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

          To set the instance attribute:
          ▸ provide the argument instance on the command line.

          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.

REQUIRED FLAGS
     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.

OPTIONAL FLAGS
     --async
        Return immediately, without waiting for the operation in progress to
        complete.

GCLOUD WIDE FLAGS
    These flags are available to all commands: --access-token-file, --account,
    --billing-project, --configuration, --flags-file, --flatten, --format,
    --help, --impersonate-service-account, --log-http, --project, --quiet,
    --trace-token, --user-output-enabled, --verbosity.

    Run $ gcloud help for details.
