CreateRule

Creates a Recycle Bin retention rule. You can create two types of retention rules:

Tag-level retention rules - These retention rules use resource tags to identify the resources to protect. For each retention rule, you specify one or more tag key and value pairs. Resources (of the specified type) that have at least one of these tag key and value pairs are automatically retained in the Recycle Bin upon deletion. Use this type of retention rule to protect specific resources in your account based on their tags.
Region-level retention rules - These retention rules, by default, apply to all of the resources (of the specified type) in the Region, even if the resources are not tagged. However, you can specify exclusion tags to exclude resources that have specific tags. Use this type of retention rule to protect all resources of a specific type in a Region.

For more information, see Create Recycle Bin retention rules in the Amazon EBS User Guide.

URI Request Parameters

The request does not use any URI parameters.

Request Body

The request accepts the following data in JSON format.

Description

The retention rule description.

Type: String

Pattern: ^[\S ]{0,255}$

Required: No

ExcludeResourceTags

[Region-level retention rules only] Specifies the exclusion tags to use to identify resources that are to be excluded, or ignored, by a Region-level retention rule. Resources that have any of these tags are not retained by the retention rule upon deletion.

You can't specify exclusion tags for tag-level retention rules.

Type: Array of ResourceTag objects

Array Members: Minimum number of 0 items. Maximum number of 5 items.

Required: No

LockConfiguration

Information about the retention rule lock configuration.

Type: LockConfiguration object

Required: No

ResourceTags

[Tag-level retention rules only] Specifies the resource tags to use to identify resources that are to be retained by a tag-level retention rule. For tag-level retention rules, only deleted resources, of the specified resource type, that have one or more of the specified tag key and value pairs are retained. If a resource is deleted, but it does not have any of the specified tag key and value pairs, it is immediately deleted without being retained by the retention rule.

You can add the same tag key and value pair to a maximum or five retention rules.

To create a Region-level retention rule, omit this parameter. A Region-level retention rule does not have any resource tags specified. It retains all deleted resources of the specified resource type in the Region in which the rule is created, even if the resources are not tagged.

Type: Array of ResourceTag objects

Array Members: Minimum number of 0 items. Maximum number of 50 items.

Required: No

ResourceType

The resource type to be retained by the retention rule. Currently, only Amazon EBS snapshots and EBS-backed AMIs are supported. To retain snapshots, specify EBS_SNAPSHOT. To retain EBS-backed AMIs, specify EC2_IMAGE.

Type: String

Valid Values: EBS_SNAPSHOT | EC2_IMAGE

Required: Yes

RetentionPeriod

Information about the retention period for which the retention rule is to retain resources.

Type: RetentionPeriod object

Required: Yes

Tags

Information about the tags to assign to the retention rule.

Type: Array of Tag objects

Array Members: Minimum number of 0 items. Maximum number of 50 items.

Required: No

LockState

[Region-level retention rules only] The lock state for the retention rule.

locked - The retention rule is locked and can't be modified or deleted.
pending_unlock - The retention rule has been unlocked but it is still within the unlock delay period. The retention rule can be modified or deleted only after the unlock delay period has expired.
unlocked - The retention rule is unlocked and it can be modified or deleted by any user with the required permissions.
