BotsRegulator(BR) is a Cloud Run service with two cron jobs flow. BR does not accept incoming requests except from these cron jobs.
go/botsregulator
go/cloudbots-gce
go/cloudbots
BR periodically look for UFS DUTs with a specific hive value and send this set of DUTs to a Bots Provider API (e.g. GCE Provider).
Used for CloudBots migration.
BR migrates/rolls back DUTs based on a migration file stored in luci-config (services/bots-regulator-dev/migration.cfg). Migrating a DUT means updating the DUT's hive to cloudbots.
Used for CloudBots migration.
Updating the list of excluded DUTs in migration.cfg does not retroactively rollback DUTs.
It only prevents new DUTs to be migrated. cleanup-bots acts as a cleanup flow and rollbacks to Drone all the excluded DUTs currently on CloudBots.
To pass a service account use -service-account-json flag.
