Features

• Run a private Valheim server on AWS ECS
• Automatically backup worlds to s3

Instructions:

• Create a directory for your local terraform state, such as valheim-terraform
• Create main.tf like so:

provider "aws" {
  region = "us-east-1"
}

module "valheim-server" {
  source         = "github.com/kpenfound/valheim-server?ref=v0.2.0"
  key_name       = "my_aws_keypair_name"
  world_name     = "Valheim-friends"
  world_password = "hunter2"
}

• terraform apply
• In Steam, go to View > Servers > Favorites > Add Server
• Add your server at {NLB DNS}:2457
• Open valheim, select the server, and click connect!

Important notes

The default ecs_ami is the current ecs optimized ami in us-east-1. You will have to change this for other regions. Refer to this list: https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs-optimized_AMI.html
