> Airflow should handle the rediss:// protocol for TLS-enable Redis
> -----------------------------------------------------------------
>
> Key: AIRFLOW-6985
> URL: https://issues.apache.org/jira/browse/AIRFLOW-6985
> Project: Apache Airflow
> Issue Type: Improvement
> Components: configuration
> Affects Versions: 1.10.9
> Reporter: Noël BARDELOT
> Priority: Major
>
> Please see the following issue for Flower:
> https://github.com/mher/flower/issues/639
> Flower and Airflow do not handle TLS-enable connections to Redis the same way. Thus, when providing the same broker URL to Flower that the one provided to Airflow, Flower cannot start/work.
> There are several issues at hand here:
> * Airflow by itself does handle its configuration correctly using `ssl_active`, but does not handle `rediss://`
> * Flower by itself handles `rediss://` but does not handle an additionnal `ssl_active` option
> * in the Helm chart for Airflow, there is no easy way to provide a configuration to Flower (Flower gets its configuration via the same configuration as Airflow, and thus cannot be correctly configured because Airflow would throw an exception)
> See airflow/config_templates/default_celery.py where an exception is raised if `rediss://` is used.
> A nice and quick fix would be to handle `rediss://` and drive the TLS-enabled mode is that protocol is used while `ssl_active` is also set to true. If `rediss://` is used but `ssl_active` is set to false, an exception could be raised to warn the user that the configuration is inconsistent.
