Filters¶
dhcp-options¶
Filter VPCs based on their dhcp options
- example
if an option value is specified as a list, then all elements must be present. if an option value is specified as a string, then that string must be present.
vpcs not matching a given option value can be found via specifying a present: false parameter.

flow-logs¶
Are flow logs enabled on the resource.
ie to find all vpcs with flows logs disabled we can do this
- example
policies:
- name: flow-logs-enabled
resource: vpc
filters:
- flow-logs
or to find all vpcs with flow logs but that don’t match a particular configuration.
- example
policies:
- name: flow-mis-configured
resource: vpc
filters:
- not:
- type: flow-logs

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).
