Airflow 2.0 and disable RBAC

[usernametakenforever]

I have noticed that in airflow 2.0.0, RBAC is enabled by default and new webserver_config.py is generated automatically. Is it possible for me to use my webserver and ldap settings in airflow.cfg from older version (1.10.12)? CPU usage on the host just went up considerably and I believe it may be due to RBAC in webserver. Please let me know if you need more informaiton.

Airflow 2.0 uses RBAC UI and it is the only UI. The old flask-admin based UI has been removed in 2.0.0

is it possible to diable auth within rbac ui? or we simply must create a user and use it to log in?

You can uncomment this line in Airflow 2.0.1 and change Public to Admin:

airflow/airflow/config_templates/default_webserver_config.py

Lines 52 to 53 in 9f14724

	# Uncomment to setup Public role name, no authentication needed
	# AUTH_ROLE_PUBLIC = 'Public'

nice! thanks.

ok i actually got it working with this setting

AUTH_ROLE_PUBLIC = 'Admin'

but there is still the login button at top right... which will probably be a bit confusing for users

Agree, worth creating an issue with FAB (https://github.com/dpgaspar/Flask-AppBuilder) I think

We also noticed an increase in CPU usage after the upgrade, but found that it was caused by the scheduler running the DagFileProcessor non-stop. I tweaked the corresponding config keys (namely "processor_poll_interval" and "min_file_process_interval"). Not sure if it was a fuck up in the upgrade process by me or the upgrade introduced new configs there.

min_file_process_interval has been changed to 30 from 0 since 2.0.1
