Prepopulate image with existing world data

[giantcow]

I come from the AWS ECS package (https://github.com/rileydakota/valheim-ecs-fargate-cdk), and I am working on allowing users to populate the docker image with a world that already exists. https://github.com/RyoshiKayo/valheim-ecs-fargate-cdk/blob/bootstrap-world/lib/valheim-server-aws-cdk-stack.ts#L98-L99

Questions:

• What is the "correct" hook to populate the world data folder?
• Where should I be copying this world data too?
  • Tried /home/valheim/.config/unity3d/IronGate/Valheim/worlds_local/ and /config/unity3d/IronGate/Valheim/worlds_local/

Check the "basic docker usage" section of the Readme. You don't really need a hook you just mount a folder that contains your worlds_local folder with worlds inside.

In the ECS package, we're deploying the drive we mount to and the container at basically the same time. It would be a lot more cumbersome to create a new container/host only to upload the world files when we could just utilize the hooks to do it for us.

Figured this out. In the ECS repo we are mounting all of /config to a Elastic File System file system. I was running into issues because the backup I took from an older Valheim server version had a different format than what this docker image was using. So I had to reformat the ZIP archive and change the destination folder

I was referencing files in /home/valheim/ because some of the log messages referenced those locations, even though it looks like we're not directly using them..
