How to add World Modifiers to this Server setup?

[GooseZ620]

Hello, How can i add World Modifiers to the server that will permanently remain active (Regardless of reboots or service restarts). I suppose i am asking the best way to do this, as i know that you can add yourself as an admin to the server and type in a command, but i think this would be removed when the server restarts.
Is there a way to bake this into the startup commands for this docker service? Thanks.

Hi,

use the environment variable SERVER_ARGS.

i assume you use docker compose to start your docker container.

docker-compose.yaml

---------------------------------------------------------------------
  ...
  environment:
      SERVER_ARGS: "-modifier combat easy"
      SERVER_NAME: "My Valheim Server"
  ...
---------------------------------------------------------------------

Unfortunately i'm a bit poor at some things as i'm not technically a dev myself, but i know enough to get around. I am running the service without docker compose as i set it up as a Linux service instead, but i will be able to edit the SERVER_ARGS, Thanks for the response i had a feeling that would be the case.
Will add the args into my sysconfig/valheim-server file :)

So i wish to add Portal items and decrease the skill reduction rate, i guess i would do something like:
SERVER_ARGS="-modifier Portal items" "setkey SkillReductionRate 75"

Bumping this - how do we add multiple modifiers? I can't seem to get it quite right. I want to set combat to easy, deathpenalty to very easy, and resourcerate to much more. How do you properly add all those modifiers? Haven't even tried setkey yet but would be curious how they all chain together.

To add multiple modifiers, simply add another modifier flag to the value. So in your case:
SERVER_ARGS="-modifier combat easy -modifier deathpenalty veryeasy -modifier resources muchmore"

I tested this but only -crossplay works, not if i add another -modifier portals normal for example?

valheim-server:
    image: ghcr.io/lloesche/valheim-server:latest
    container_name: valheim-server
    restart: unless-stopped
    cap_add:
      - sys_nice
    stop_grace_period: 120s
    ports:
      - "2456-2458:2456-2458/udp"
      - "80:80/tcp"
      - "9001:9001/tcp"
    volumes:
      - ./config:/config:Z
      - ./data:/opt/valheim:Z
    environment:
      SERVER_NAME: "x"
      WORLD_NAME: "x"
      SERVER_PASS: "x"
      SERVER_ADMIN_PASSWORD: "x"
      SERVER_PUBLIC: "true"
      SERVER_ARGS: "-crossplay -modifier portals normal"
      BACKUPS_DIRECTORY: "/config/backups"
      STATUS_HTTP: true
      STATUS_HTTP_PORT: "80"
      STATUS_HTTP_CONF: "/config/httpd.conf"
      SUPERVISOR_HTTP: true
      SUPERVISOR_HTTP_PORT: "9001"
      SUPERVISOR_HTTP_USER: "admin"
      SUPERVISOR_HTTP_PASS: "admin123"

I believe I can confirm SERVER_ARGS does not appear to actually propagate to the startup scripts Docker generates. So this doesn't work now (it may have previously).

Modifiers do not interact with this mod. Add modifiers as start parameters, add Addon to Server and all Clients, maybe make config changes, after initial start in the config file relating to this mod.
