------------------------------------

             Summary: Links to configurations, version does not respect base_url with subpath
                 Key: AIRFLOW-5429
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-5429
             Project: Apache Airflow
          Issue Type: Bug
          Components: ui
    Affects Versions: 2.0.0
            Reporter: Mark Rebuck


We deploy airflow instances to hosts where the base_url is of the form [http://foo.bar.com/x] or [http://foo.bar.com/y]  Most the UI works correctly, but following the "Admin -> Configurations" menu item, or "About -> Version" both result in 404's.  They take the user to [http://foo.bar.com/configuration] or [http://foo.bar.com/version] instead of including the "/x" or "/y" parts of the base_url, e.g. [http://foo.bar.com/x/configuration] (which works).

 

I'm not a Flask expert, but I suspect the issue might be one of:

1.  [https://github.com/apache/airflow/blob/f497d1d5aad9d88d6c1cd1dfa28546e7a8c5cb5f/airflow/www/app.py#L132] and [https://github.com/apache/airflow/blob/f497d1d5aad9d88d6c1cd1dfa28546e7a8c5cb5f/airflow/www/app.py#L155] , where the href parameter is hardcoded with a leading "/", or...

2.   [https://github.com/apache/airflow/blob/master/airflow/www/views.py#L1980] , where the call to render_template() does not supply the root parameter.  Other functions, e.g. 'code' action, do a root=request.args.get('root') as a parameter to render_template().

 

I apologize for not providing a PR with a suggested fix.  I can't currently build the Docker image from source in order to test/verify.
