list-allowed-node-type-modifications

Description

Lists all available node types that you can scale your Redis cluster’s or replication group’s current node type.

When you use the ModifyCacheCluster or ModifyReplicationGroup operations to scale your cluster or replication group, the value of the CacheNodeType parameter must be one of the node types returned by this operation.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  list-allowed-node-type-modifications
[--cache-cluster-id <value>]
[--replication-group-id <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--cache-cluster-id (string)

The name of the cluster you want to scale up to a larger node instanced type. ElastiCache uses the cluster id to identify the current node type of this cluster and from that to create a list of node types you can scale up to.

Warning

You must provide a value for either the CacheClusterId or the ReplicationGroupId .

--replication-group-id (string)

The name of the replication group want to scale up to a larger node type. ElastiCache uses the replication group id to identify the current node type being used by this replication group, and from that to create a list of node types you can scale up to.

Warning

You must provide a value for either the CacheClusterId or the ReplicationGroupId .

--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.

Examples

To list the allowed node modifications

The following list-allowed-node-type-modifications example lists all the available node types that you can scale your Redis cluster’s or replication group’s current node type to.

aws elasticache list-allowed-node-type-modifications \
    --replication-group-id "my-replication-group"

Output:

{
    "ScaleUpModifications": [
        "cache.m5.12xlarge",

Output

ScaleUpModifications -> (list)

A string list, each element of which specifies a cache node type which you can use to scale your cluster or replication group.

When scaling up a Redis cluster or replication group using ModifyCacheCluster or ModifyReplicationGroup , use a value from this list for the CacheNodeType parameter.

(string)

ScaleDownModifications -> (list)

A string list, each element of which specifies a cache node type which you can use to scale your cluster or replication group. When scaling down a Redis cluster or replication group using ModifyCacheCluster or ModifyReplicationGroup, use a value from this list for the CacheNodeType parameter.
