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
  selector_value:
    type: string
  type:
    enum:

delete

Action to delete rds cluster snapshots

To prevent unwanted deletion of rds cluster snapshots, it is recommended to apply a filter to the rule

example:

policies:
  - name: rds-cluster-snapshots-expired-delete
    resource: rds-cluster-snapshot
    filters:
      - type: age
        days: 30
        op: gt
    actions:
      - delete

properties:
  type:
    enum:
    - delete
required:
- type

Permissions - rds:DeleteDBClusterSnapshot

region-copy

Copy an cluster snapshot across regions

Example:

- name: copy-encrypted-cluster-snapshots
  description: |
    copy cluster snapshots under 1 day old to dr region with kms
  resource: rds-cluster-snapshot
  region: us-east-1
  filters:
   - Status: available
   - type: value
     key: SnapshotCreateTime
     value_type: age
     value: 1
     op: less-than
  actions:
    - type: region-copy
      target_region: us-east-2
      target_key: arn:aws:kms:us-east-2:644160558196:key/b10f842a-feb7-4318-92d5-0640a75b7688
      copy_tags: true
      tags:
        OriginRegion: us-east-1

properties:
  copy_tags:
    type: boolean
  tags:
    type: object
  target_key:
    type: string
  target_region:
    type: string
  type:
    enum:
    - region-copy
required:
- target_region

Permissions - rds:CopyDBClusterSnapshot

rename-tag

Rename an existing tag key to a new value.

example:

rename Application, and Bap to App, if a resource has both of the old keys then we’ll use the value specified by Application, which is based on the order of values of old_keys.

policies:
- name: rename-tags-example
  resource: aws.log-group
  filters:
    - or:
      - "tag:Bap": present
      - "tag:Application": present
  actions:
    - type: rename-tag
      old_keys: [Application, Bap]
      new_key: App

properties:
  new_key:
    type: string
  old_key:
    type: string
  old_keys:
    items:
      type: string
    type: array
  type:
    enum:
    - rename-tag
required:
- type

Permissions - tag:TagResources, tag:UntagResources

set-permissions

Set permissions for copying or restoring an RDS cluster snapshot

Use the ‘add’ and ‘remove’ parameters to control which accounts to add or remove, respectively. The default is to remove any permissions granted to other AWS accounts.

Use remove: matched in combination with the cross-account filter for more flexible removal options such as preserving access for a set of whitelisted accounts:

example:

policies:
  - name: rds-cluster-snapshot-prune-permissions
    resource: rds-cluster-snapshot
    filters:
      - type: cross-account
        whitelist:
          - '112233445566'
    actions:
      - type: set-permissions
        remove: matched

properties:
  add:
    items:
      oneOf:
      - maxLength: 12
        minLength: 12
        type: string
      - enum:
        - all
    type: array
  remove:
    oneOf:
    - enum:
      - matched
    - items:
        oneOf:
        - maxLength: 12
          minLength: 12
          type: string
        - enum:
          - all
