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).

  selector:
    enum:
    - previous
    - date
    - locked

    resource: rds-snapshot
    filters:
      - type: age
        days: 28

Permissions - rds:DeleteDBSnapshot

region-copy

Copy a snapshot across regions.

Note there is a max in flight for cross region rds snapshots of 5 per region. This action will attempt to retry automatically for an hr.

Example:

- name: copy-encrypted-snapshots
  description: |
    copy snapshots under 1 day old to dr region with kms
  resource: rds-snapshot
  region: us-east-1
  filters:
   - Status: available

Permissions - rds:CopyDBSnapshot

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

Permissions - tag:TagResources, tag:UntagResources

restore

Restore an rds instance from a snapshot.

Note this requires the snapshot or db deletion be taken with the copy-restore-info boolean flag set to true, as various instance metadata is stored on the snapshot as tags.

additional parameters to restore db instance api call be overriden via restore_options settings. various modify db instance parameters can be specified via modify_options settings.

properties:
  modify_options:
    type: object
  restore_options:
    type: object

    enum:
    - restore
required:
- type

Permissions - rds:ModifyDBInstance, rds:ModifyDBParameterGroup, rds:ModifyOptionGroup, rds:RebootDBInstance, rds:RestoreDBInstanceFromDBSnapshot

set-permissions

Set permissions for copying or restoring an RDS 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-snapshot-remove-cross-account
    resource: rds-snapshot
    filters:
      - type: cross-account
        whitelist:
          - '112233445566'

        remove: matched
