aws.rds-cluster

Resource manager for RDS clusters.

Filters

consecutive-aws-backups

Returns resources where number of consective backups (based on the periodicity defined in the filter) is equal to/or greater than n units. This filter supports the resources that use AWS Backup service for backups.

example:

policies:
  - name: dynamodb-consecutive-aws-backup-count
    resource: dynamodb-table
    filters:
      - type: consecutive-aws-backups
        count: 7
        period: days
        status: 'COMPLETED'
properties:
  count:
    minimum: 1
    type: number
  period:
    enum:
    - hours
    - days
    - weeks
  status:
    enum:
    - COMPLETED

  type:
    enum:
    - consecutive-aws-backups
required:
- count

Permissions - backup:ListRecoveryPointsByResource

consecutive-snapshots

Returns RDS clusters where number of consective daily snapshots is equal to/or greater

than n days.

example:

policies:

      - type: consecutive-snapshots

json-diff

Compute the diff from the current resource to a previous version.

A resource matches the filter if a diff exists between the current resource and the selected revision.

Utilizes config as a resource revision database.

Revisions can be selected by date, against the previous version, and against a locked version (requires use of is-locked filter).

properties:
  selector:
    enum:
    - previous
    - date
    - locked

kms-key

Filter a resource by its associated kms key and optionally the aliasname of the kms key by using ‘c7n:AliasName’

example:

Match a specific key alias:

policies:
    - name: dms-encrypt-key-check
      resource: dms-instance
      filters:
        - type: kms-key
          key: "c7n:AliasName"
          value: alias/aws/dms

Or match against native key attributes such as KeyManager, which more explicitly distinguishes between AWS and CUSTOMER-managed keys. The above policy can also be written as:

policies:
    - name: dms-aws-managed-key
      resource: dms-instance
      filters:
        - type: kms-key
          key: KeyManager

To prevent unwanted deletion of clusters, it is recommended to apply a filter to the rule

policies:
  - name: rds-cluster-delete-unused
    resource: rds-cluster
    filters:
      - type: metrics
