marked-for-op

Filter resources for label specified future action

Filters resources by a ‘custodian_status’ label which specifies a future date for an action.

The filter parses the label values looking for an ‘op@date’ string. The date is parsed and compared to do today’s date, the filter succeeds if today’s date is gte to the target date.

The optional ‘skew’ parameter provides for incrementing today’s date a number of days into the future. An example use case might be sending a final notice email a few days before terminating an instance, or snapshotting a volume prior to deletion.

The optional ‘skew_hours’ parameter provides for incrementing the current time a number of hours into the future.

Optionally, the ‘tz’ parameter can get used to specify the timezone in which to interpret the clock (default value is ‘utc’)

example:

policies:
 - name: vm-stop-marked
   resource: gcp.instance
   filters:
     - type: marked-for-op
       # The default label used is custodian_status
       # but that is configurable
       label: custodian_status
       op: stop
       # Another optional label is skew
       tz: utc

delete

Invoke an api call on each resource.

Quite a number of procedural actions are simply invoking an api call on a filtered set of resources. The exact handling is mostly boilerplate at that point following an 80/20 rule. This class is an encapsulation of the 80%.

mark-for-op

Label resources for future action.

The optional ‘tz’ parameter can be used to adjust the clock to align with a given timezone. The default value is ‘utc’.

If neither ‘days’ nor ‘hours’ is specified, Cloud Custodian will default to marking the resource for action 4 days in the future.

example:

policies:
 - name: vm-mark-for-stop
   resource: gcp.instance
   filters:
     - type: value
       key: name
       value: instance-to-stop-in-four-days
