How to set up a Core Keeper dedicated server

What HaruHost does for you

• SteamCMD: not needed. HaruHost downloads the dedicated server and updates it with one button.
• Settings: on Windows, Auto Config sets world name, seed, world mode, season, password and max players; see server settings.
• Getting friends in: with the Tunnel, no port forwarding, even behind CGNAT.
• Bans: see the server's bans, and ban or unban players while it is stopped.
• An existing server: on Windows, import it by its folder, with its world and settings.

On Windows

1. Download HaruHost for Windows and sign in.
2. Choose Add → New game server, pick this PC, then Core Keeper.
3. On the Connection step, choose Tunnel to skip router setup, or Ports to use your own address.
4. Create the server and start it.
5. Send friends the Server Address from the server's Details tab.

Install HaruHost on Linux

On Ubuntu (x86-64), run:

curl -fsSL https://haruhost.com/install.sh | sudo bash

HaruHost installs as a service. Sign in with the QR code it shows in your SSH session, then open the web panel from any browser. On Ubuntu it installs Docker with one click when you create your first server.

On Linux

1. In the web panel, choose Add → New game server, pick your Linux server, then Core Keeper.
2. On the Connection step, choose Tunnel, or Ports to use the server's own address. The Tunnel needs HaruHost running as a service, as the install command sets it up.
3. Create the server. If Docker isn't installed yet, HaruHost asks first; press Install, then Create Server.
4. Start the server and send friends the Server Address from the Details tab.
