Airflow with docker compose in specific path

[Jorge_Eduardo_Trujil (Jorge Eduardo Trujillo Velázquez)]

Hi, I have this docker compose file in my ubuntu machine

https://airflow.apache.org/docs/apache-airflow/2.8.0/docker-compose.yaml

and created the Caddyfile

merc-reports.edu/flow {

  tls /etc/caddy/ssl/merc-reports_cert.pem /etc/caddy/ssl/merc-reports.key

  redir /(.*) /flow/$1
  reverse_proxy airflow-webserver:8080

}

I intend airflow to be shown in /flow/ not in the root directory. But when I execute this I get the error:

Airflow 404
Page cannot be found.

Is it possible to help how to define the caddy file?

I’m guessing that this app is not expecting to be served on /flow/?

It’s possible that it might function if you strip the /flow/ path from the URI before proxying the request to Airflow. It’s also possible that it might “work” but with errors - missing assets like images, JavaScript and the like. I wrote a bit about this particular class of issue:

The "subfolder problem", OR, "why can't I reverse proxy my app into a subfolder?"

Have you ever tried to reverse proxy an app into its own little subfolder of your domain name? Makes things neat, doesn’t it? Using example.com/foo/ for one app, example.com/bar/ for another. If you’re coming here from one of the selfhosted communities, you might be thinking along the lines of example.com/sonarr/, example.com/radarr/ etc. Chances are, you’ve tried some configuration along these lines: example.com { redir /sonarr /sonarr/ handle_path /sonarr/* { reverse_proxy localhost…

If you want to try stripping the path and see if that works, you can use something like the example at the top of that post, using handle_path to take care of it.
