airflow webserver + base url prefix + nginx reverse proxy

[Yacine Chantit <Ya...@thetrainline.com>]

Hi all,
I am trying to test the reverse proxy feature (available from this PR : https://github.com/apache/incubator-airflow/pull/2952)
The feature is not release yet so I am testing it from the master branch.
I am following the doc here : https://github.com/apache/incubator-airflow/blob/master/docs/integration.rst
I have updated the base_url property in the airflow.cfg and set the server conf of nginx :
# base_url in airflow.cfg
base_url = http://localhost/airflow/

## nginx conf :
server {
    listen 80;
    server_name localhost;
    location /airflow {
      proxy_pass http://localhost:8080/;
      proxy_set_header Host $host;
      proxy_redirect off;
      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection "upgrade";
    }
}


I keep getting a 404 error when I hit : http://localhost/airflow because the server send a redirect response with location header set to  http://localhost/admin and the /admin location is not defined in my nginx.  I want all of the airflow webserver to be under /airflow .

When I hit http://localhost/airflow/admin it works but all the links on the pages refer to /admin so it’s not good. It looks like the base_url property is not taken into account ?
Anyone have seen this before or have the reverse proxy with airflow webserver ? Many thanks
