Hi all,
An option worth considering is Ansible AWX (the open-source version of Ansible Tower).
It allows you to:
Schedule jobs easily (no need for external crons),
Track job executions and results in a clear web UI,
Manage credentials and inventories securely,
And of course, execute Ansible playbooks or ad-hoc commands conditionally across multiple servers and databases.
For your use case — running SQL queries on specific databases that meet certain criteria — you could write lightweight Ansible playbooks and let AWX handle the orchestration, scheduling, and logging.
It’s simple to set up and provides much better visibility and control than scattered bash scripts.
Best,
Bertrand
ps.: i am using AWX every day for this kind of job

Well, I'd just use psql, with some simple script using \gexec
functionality. Solves virtually any problem of this kind.
Ditto. bash scripts are only ugly if you write ugly bash.
