How can I run php cecil.phar serve inside DDEV

[terryupton]

I am trying to use Cecil inside DDEV (which is build on docker).

When I expose the ports in DDEV config like so:

web_extra_exposed_ports:
  - name: cecil
    container_port: 8000
    http_port: 7999
    https_port: 8000

I am getting a 404 error.

Any ideas how I can get Cecil to serve inside DDEV?

If I build the site and set the webroot to _site in the DDEV config then I can load it.
But I would like to use the serve for building.
