Delete GCP instances without valid `lifetime` tag

Use this workflow

This workflow looks at all of the GCP instances in a given account and zone and selects a subset of those to terminate. The termination criteria are:

  • Not labelled with a termination_date or lifetime after 4 mintutes
  • The termination_date or lifetime labels are present but cannot be parsed.
  • The termination_date or lifetime labels indicate that the instance has expired.

An instance may be configured to never terminate if its lifetime label has the special value indefinite. Other valid values for the lifetime label are of the form <number><unit> where <number> is any integer and <unit> is a time unit of w(weeks), h(hours), d(days) or m(months). So, as an example, if the lifetime label for an instance has a value of 43w then it should be terminated after it's 43 weeks old.


Relay uses YAML to define the steps in a workflow.


Each step in the workflow is visualized below.
