terraform-valheim

Some templates to deploy valheim server. Could be a lot more abstract, just need a server real quick.

Usage

Setup gcloud CLI

1. Download and install the gcloud sdk
2. Run gcloud init
3. Select your project and accept the oauth prompt
4. Run gcloud auth application-default login and accept the oauth prompt

Setup terraform

1. Download and install terraform 1.0.7+
2. Update var.provider_project_id in provider-variables.tf with the same project ID ... todo, generate ssh keys instead of the coded paths, assumes you have an ~/.ssh/id_rsa and ~/.ssh/id_rsa.pub already
3. Run terraform init
4. Run terraform apply -target=google_project_service.compute
5. Run terraform apply

Troubleshooting

The machine which you used to provision these templates is allowed through the firewall, so you can get the current IP of the provisioned instance like:

terraform state show google_compute_instance.this | grep nat_ip

Then ssh there via ssh ubuntu@<the-ip-from-above>

In it's current form, there is a systemd service unit of the app, so you can:

journalctl -fu valheim

Restoring from backup

By default, backups of the world are zipped every hour under /var/lib/valheim/valheim/config/backups. If you override ${var.server_name} to 'example' it would be /var/lib/valheim/example/config/backups.

Using the 'example' world, say you have a zipped backup named /tmp/worlds-20210321-020002.zip. You would need to provision a new server or reusing an existing deployment, then:

service valheim stop
pushd /var/lib/valheim/example/config
unzip -o /tmp/worlds-20210321-020002.zip
service valheim start
