We are running Airflow 1.10, we have scheduled ~50 DAGs. We are using local timezone, last night when during timezone change (DST change, Sunday 3AM->2AM) scheduler stopped scheduling the dags. Scheduler processes were up, but no jobs were scheduler. Restart didn't help. We had to set up Airflow on clean database.
change system clock to 28 Oct 1.45 CEST (UTC +02.00)
docker-compose up -d
Go to
localhost:8080
and turn on the dag (there is only one)
Dag should start to be invoked every 5 minutes. After ~1 hour when time is changed automatically to 28 Oct 2.00 CET (UTC +01.00) there will be no any further executions (even when you wait 1 or 2 hours more, still no execution)
One can log into container and check the status, logs, etc:
docker exec -i -t airflow /bin/bash
