Hey Julierme,
I think the geoserver data volume is mounted under
/geoserver_data/data
to your django container.
Can you log to the container, check the path and if
it´s correct try this with your sld?
cheers,
Toni

Find geo.sld bellow working smoothly on GeoServer at 2.14.1 and a screenshot of tb_brasilia_weather layer. Now, I am doing the same thing in my GeoNode at 2.8 in a CenTos7 Server installed via Docker and GeoServer at 2-13-SNAPSHOT in geoserver4my_geonode container.
