delete-cluster¶

Description¶

Deletes a cluster. It also deletes all associated nodes and node endpoints

Synopsis¶

  delete-cluster
--cluster-name <value>
[--final-snapshot-name <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--cluster-name (string)

The name of the cluster to be deleted

--final-snapshot-name (string)

The user-supplied name of a final cluster snapshot. This is the unique name that identifies the snapshot. MemoryDB creates the snapshot, and then deletes the cluster immediately afterward.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To delete a cluster

The following delete-cluster example deletes a cluster.

aws memorydb delete-cluster \
    --cluster-name my-new-cluster

Output:

        "AutoMinorVersionUpgrade": true
    }
}

The status of the cluster. For example, Available, Updating, Creating.

PendingUpdates -> (structure)

A group of settings that are currently being applied.

Resharding -> (structure)

The status of an online resharding operation.

SlotMigration -> (structure)

The status of the online resharding slot migration

ProgressPercentage -> (double)

The percentage of the slot migration that is complete.

ACLs -> (structure)

A list of ACLs associated with the cluster that are being updated

ACLToApply -> (string)

A list of ACLs pending to be applied.

ServiceUpdates -> (list)

A list of service updates being applied to the cluster

(structure)

Update action that has yet to be processed for the corresponding apply/stop request

The unique ID of the service update

Status -> (string)

The status of the service update

NumberOfShards -> (integer)

The number of shards in the cluster

Shards -> (list)

A list of shards that are members of the cluster.

(structure)

Nodes -> (list)

A list containing information about individual nodes within the shard

(structure)

Represents an individual node within a cluster. Each node runs its own instance of the cluster’s protocol-compliant caching software.

Name -> (string)

The node identifier. A node name is a numeric identifier (0001, 0002, etc.). The combination of cluster name, shard name and node name uniquely identifies every node used in a customer’s Amazon account.

Status -> (string)

The status of the service update on the node

AvailabilityZone -> (string)

The Availability Zone in which the node resides

CreateTime -> (timestamp)

The date and time when the node was created.

Endpoint -> (structure)

The hostname for connecting to this node.

Address -> (string)

The DNS hostname of the node.

Port -> (integer)

The port number that the engine is listening on.

NumberOfNodes -> (integer)
