How can I add folders and files to a docker container running on ECS?

Question

Assuming I have the following docker-compose

version: "3.9"

services:
  skyrimserver:
    container_name: skyrimserver
    image: tiltedphoques/st-reborn-server:latest
    ports:
      - "10578:10578/udp"
    volumes:
     - /opt/docker/skyrimserver/config:/home/server/config
     - /opt/docker/skyrimserver/logs:/home/server/logs
     - /opt/docker/skyrimserver/Data:/home/server/Data
    restart: unless-stopped

I would like to have the folders specified under volumes created & filled with some files before running it. It seems like the docker integration creates a EFS file system automatically which is empty. How can I hook into that to add files upon creation?

EDIT: A nice solution would be to have the ability to change the config on-the-fly and reloading within the game, not having to restart the whole server because the new docker file includes new configuration files

Answer 1

docker compose is a tool to define run docker. When you define volumes in yaml file it's similar to run docker with arg --mount

What you need with ECS is a fully functioning image with all sources of files in it, using a Dockerfile like this to build image might work:

FROM tiltedphoques/st-reborn-server

CP /opt/docker/skyrimserver/config /home/server/config
CP /opt/docker/skyrimserver/logs /home/server/logs
CP /opt/docker/skyrimserver/Data /home/server/Data

EXPOSE 10578
