Actions defined by Amazon MemoryDB
You can specify the following actions in the Action element of an IAM policy statement. Use policies to grant permissions to perform an operation in AWS. When you use an action in a policy, you usually allow or deny access to the API operation or CLI command with the same name. However, in some cases, a single action controls access to more than one operation. Alternatively, some operations require several different actions.
The Resource types column of the Actions table indicates whether each action supports resource-level permissions. If there is no value for this column, you must specify all resources ("*") to which the policy applies in the Resource element of your policy statement. If the column includes a resource type, then you can specify an ARN of that type in a statement with that action. If the action has one or more required resources, the caller must have permission to use the action with those resources. Required resources are indicated in the table with an asterisk (*). If you limit resource access with the Resource element in an IAM policy, you must include an ARN or pattern for each required resource type. Some actions support multiple resource types. If the resource type is optional (not indicated as required), then you can choose to use one of the optional resource types.
The Condition keys column of the Actions table includes keys that you can specify in a policy statement's Condition element. For more information on the condition keys that are associated with resources for the service, see the Condition keys column of the Resource types table.
Note
Resource condition keys are listed in the Resource types table. You can find a link to the resource type that applies to an action in the Resource types (*required) column of the Actions table. The resource type in the Resource types table includes the Condition keys column, which are the resource condition keys that apply to an action in the Actions table.
For details about the columns in the following table, see Actions table.
Note
When you create a MemoryDB for Redis policy in IAM you must use the "*" wildcard character for the Resource block. For information about using the following MemoryDB for Redis API actions in an IAM policy, see MemoryDB Actions and IAM.

Resource types defined by Amazon MemoryDB
The following resource types are defined by this service and can be used in the Resource element of IAM permission policy statements. Each action in the Actions table identifies the resource types that can be specified with that action. A resource type can also define which condition keys you can include in a policy. These keys are displayed in the last column of the Resource types table. For details about the columns in the following table, see Resource types table.
| Resource types | ARN | Condition keys |
|---|---|---|
| parametergroup |
arn:${Partition}:memorydb:${Region}:${Account}:parametergroup/${ParameterGroupName}
|
|
| subnetgroup |
arn:${Partition}:memorydb:${Region}:${Account}:subnetgroup/${SubnetGroupName}

Condition keys for Amazon MemoryDB
Amazon MemoryDB defines the following condition keys that can be used in the Condition element of an IAM policy. You can use these keys to further refine the conditions under which the policy statement applies. For details about the columns in the following table, see Condition keys table.
To view the global condition keys that are available to all services, see Available global condition keys.
| Condition keys | Description | Type |
|---|---|---|
| aws:RequestTag/${TagKey} | Filters actions based on the tags that are passed in the request | String |
| aws:ResourceTag/${TagKey} | Filters actions based on the tags associated with the resource | String |
