I'm not very experienced with manually adding docker containers via compose, so forgive me if this is the wrong place to ask. I was able to successfully add openbooks to my Unraid server via docker compose, but for some reason all the files it downloads come in with r-- read only permissions. I naively tried adding the PUID=99, PGID=100, and UMASK=002 lines to the environment section, thinking that might help, but no luck. Is what I am trying to do not possible?

version: '3.3'
services:
    openbooks:
        ports:
            - '8585:80'
        volumes:
            - '/mnt/user/data/downloads:/books'
        restart: unless-stopped
        container_name: OpenBooks
        command: --name <username> --persist
        environment:
          - BASE_PATH=/openbooks/
          - PUID=99
          - PGID=100
          - UMASK=002
        image: evanbuss/openbooks:latest

volumes:
    booksVolume:

 

Never mind! Was able to fix it by using the following docker compose:

version: '3.3'
services:
    openbooks:
        container_name: OpenBooks
        image: evanbuss/openbooks:latest
        ports:
            - "8585:80"
        volumes:
            - '/mnt/user/data/media/eBooks/to_import:/books'
        command: --name my_irc_name --persist --no-browser-downloads
        restart: unless-stopped
        environment:
          - BASE_PATH=/openbooks/
        user: "99:100"
volumes:
    booksVolume:
