Decommissioning Zappa

Once the SAM stacks have run without a rollback for an agreed soak period:

  1. Remove the Zappa deployments. Run zappa undeploy prod_rules2 and zappa undeploy test_rules2 from a checkout of e888027 (the Zappa settings are no longer on the new branches), or delete the functions, the ny63bqmiol API and the EventBridge rules named in Zappa to SAM cutover by hand.

  2. Delete leftovers that point at functions that no longer exist (production account):

  3. Delete the Zappa buckets app-eventlogger—​prod-rules2 (production) and app-eventlogger—​test-rules-dev (staging), after emptying them.

  4. Remove the legacy CodeBuild project EventLoggerApp once no branch needs it, or keep the webhook filter from the cutover preparation.
