The container image is published as ghcr.io/community-valheim-tools/valheim-server. On first start, the container downloads the Valheim dedicated server from Steam. The project includes support for BepInEx and ValheimPlus mods, and the server can update automatically.
The project's documentation covers Docker commands, environment variables, backups, Discord notifications, and several deployment methods, including Docker with systemd, Docker Compose, Kubernetes, AWS ECS, and Nomad. Players connecting over the internet from behind NAT need UDP ports 2456 to 2457 forwarded to the container host.
