The media url 404

[naivewen]

How can I make the right conf of the media? When I access the media,the nginx shows 404. But the static url is right!

This is the part of local.py

#MEDIA_ROOT = os.path.join(BASE_DIR, "media")
MEDIA_ROOT = '/home/taiga/media'
#STATIC_ROOT = os.path.join(BASE_DIR, "static")
STATIC_ROOT = '/home/taiga/static'

And the default.conf

# Static files
location /static {
    alias /taiga/static;
}

# Media files
location /media {
    alias /taiga/media;
}

How can I fix the error?
Regards.

OH！ I find the problem that it doesn't have the media volumes ! How can I add the volumes without the dockerFile?
