[ aws . elasticache ]



Creates a new cache subnet group.

Use this parameter only when you are creating a cluster in an Amazon Virtual Private Cloud (Amazon VPC).

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.


--cache-subnet-group-name <value>
--cache-subnet-group-description <value>
--subnet-ids <value>
[--tags <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]


--cache-subnet-group-name (string)

A name for the cache subnet group. This value is stored as a lowercase string.

Constraints: Must contain no more than 255 alphanumeric characters or hyphens.

Example: mysubnetgroup

--cache-subnet-group-description (string)

A description for the cache subnet group.

--subnet-ids (list)

A list of VPC subnet IDs for the cache subnet group.



"string" "string" ...

--tags (list)

A list of tags to be added to this resource. A tag is a key-value pair. A tag key must be accompanied by a tag value, although null is accepted.


A tag that can be added to an ElastiCache cluster or replication group. Tags are composed of a Key/Value pair. You can use tags to categorize and track all your ElastiCache resources, with the exception of global replication group. When you add or remove tags on replication groups, those actions will be replicated to all nodes in the replication group. A tag with a null Value is permitted.

Key -> (string)

The key for the tag. May not be null.

Value -> (string)

The tag’s value. May be null.

Shorthand Syntax:

Key=string,Value=string ...

JSON Syntax:

    "Key": "string",
    "Value": "string"

--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.

See ‘aws help’ for descriptions of global parameters.



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 create a cache subnet group

The following create-cache-subnet-group example creates a new cache subnet group.

aws elasticache create-cache-subnet-group \
    --cache-subnet-group-name "mygroup" \
    --cache-subnet-group-description "my subnet group" \
    --subnet-ids "subnet-xxxxec4f"


    "CacheSubnetGroup": {
        "CacheSubnetGroupName": "mygroup",
        "CacheSubnetGroupDescription": "my subnet group",
        "VpcId": "vpc-a3e97cdb",
        "Subnets": [
                "SubnetIdentifier": "subnet-xxxxec4f",
                "SubnetAvailabilityZone": {
                    "Name": "us-west-2d"
