Serving Django static images

[JeronimoMendes (Jerónimo Mendes)]

1. Caddy version (caddy version):

v2.5.0

2. How I run Caddy:

systemctl start caddy

a. System environment:

Linux

c. Service/unit/compose file:

Docker-compose.yml:

services:
  db:
    image: postgres
    volumes:
      - ./data/db:/var/lib/postgresql/data
    environment:
      - POSTGRES_DB=postgres
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=postgres

  backend:
    image: arquimedia-backend
    volumes:
      - ./data/backend:/code/static/images
    depends_on:
      - db
    environment:
    command: gunicorn Arquimedia.wsgi:application --bind 0.0.0.0:8000
    ports:
      - 127.0.0.1:8001:8000

  frontend:
    image: arquimedia-frontend
    restart: always
    depends_on:
      - backend
    command: "nginx -g 'daemon off;'"
    ports:
      - 127.0.0.1:8002:3000

d. My complete Caddyfile or JSON config:

arquimedia.pt, www.arquimedia.pt {
        encode gzip zstd

        handle /api/* {
                uri strip_prefix /api
                file_server <project-path>/data/backend/*

                @notStatic {
                         not path /images/*
                 }

                reverse_proxy @notStatic localhost:8001
        }

        handle {
                reverse_proxy localhost:8002
        }
}

3. The problem I’m having:

I’m trying to get static files on <project-path>/data/backend but the response come as a blank page, either for existing files or non existing.

1. Caddy version (caddy version):

v2.5.0

Please upgrade to v2.5.1

@JeronimoMendes

file_server <project-path>/data/backend/*

This is invalid syntax. You need to use the root directive to set where Caddy should look for files.

@JeronimoMendes

        handle /api/* {
                uri strip_prefix /api

You can use handle_path instead of handle + uri strip_prefix, because handle_path has built-in prefix stripping (if I understand correctly that your images are within /api )

I would write your config like this:

arquimedia.pt, www.arquimedia.pt {
	encode gzip zstd

	handle /api/images* {
		uri strip_prefix /api

		root * /project/path/data/backend
		file_server
	}

	handle_path /api/* {
		reverse_proxy localhost:8001
	}

	handle {
		reverse_proxy localhost:8002
	}
}
