Palworld Dedicated Server Collection for Ansible

This is an Ansible collection for deploying and managing Palworld Dedicated Server, a dedicated server application for Palworld, a popular multiplayer capable open-world survival game.

This collection should make it easier to bring Palworld Dedicated Server under configuration management on dedicated hardware or an IaaS cloud instance, which is a recommended way of running Palworld as it is very resource intensive.

Palworld Dedicated Server is orchestrated as a Docker container on a standard machine, managed by Docker Compose. The Docker container used is jammsen/palworld-dedicated-server, a regularly maintained container for Palworld Dedicated Server with strong community support, that eliminates the usual manual setup steps required for configuring Palworld.

From version 2.0.0, this collection can optionally setup a Prometheus exporter for Palworld Dedicated Server (designed by palworld.lol) alongside your server. This enables localised metrics collection from your dedicated server, which can then be turned into dashboards using Grafana.

Requirements

This collection currently only supports Linux target hosts. Currently, only Ubuntu 22.04 LTS is being tested and confirmed to work properly, but it should work correctly on newer versions, and other distributions as well (e.g. Debian, Red Hat).

The following applications are required to be installed and running on target hosts:

Docker
Docker Compose V2 (as a Docker plugin)

Architecture

The following file structure is created by the Ansible collection on the target host.

/opt/palworld-dedicated-server - Palworld install directory (configurable)
- data - Palworld data directory, mounted into the container (Steam binaries, game configuration, world save data)
- docker-compose.yml - Compose file (service container configuration)

Inventory

A number of inventory variables need to be set on the host to be able to deploy Palworld Dedicated Server to it.

Required

The following inventory variables are required to be set on the hosts that Palworld will be installed.

`palworld_dedicated_server_admin_password`

New in version 2.0.0.

Administrator password for the server.

Used as the password when connecting to the RCON remote administration interface, and used internally to allow additional supporting servers to connect to the dedicated server, such as the Prometheus exporter.

palworld_dedicated_server_admin_password: "{{ vault_palworld_dedicated_server_admin_password }}"  # Store the value in Ansible Vault.

`palworld_dedicated_server_settings`

Changed in version 2.0.0: The ADMIN_PASSWORD field is no longer used by the collection. The administrator password for the dedicated server must now be set using the palworld_dedicated_server_admin_password inventory variable.

This variable defines the game settings for the Palworld Dedicated Server. These will be set as environment variables in the container.

The following settings are required or highly recommended to be changed:

SERVER_NAME - Name of the Palworld Dedicated Server as shown in Palworld. Required.
SERVER_PASSWORD - Set the password required to access the server, or set to a blank string to not require a password. Required.
SERVER_DESCRIPTION - Description of the server when viewed from Palworld.
PUBLIC_IP - Public IP address of the server, as accessible from the Internet.
COMMUNITY_SERVER - Set to true if this is a community server, and false if it is a private server. When set to false, the server will not be added to the Palworld server list. Default is true.

This is how these would be set in the Ansible inventory:

palworld_dedicated_server_settings:
  SERVER_NAME: Palworld Dedicated Server Ansible Collection
  SERVER_DESCRIPTION: Palworld Dedicated Server automatically provisioned from an Ansible collection.
  SERVER_PASSWORD: "{{ vault_palworld_dedicated_server_server_password }}"  # Store the value in Ansible Vault.
  PUBLIC_IP: "192.0.2.1"
  COMMUNITY_SERVER: false

For more information on the available options, refer to the environment variable documentation.

When setting a value here, make sure the type of the value is correct in Ansible, as the compose file template converts the values to environment variable definitions.

Take, for example, the following settings definition.

palworld_dedicated_server_settings:
  SERVER_NAME: Palworld Dedicated Server Ansible Collection  # String type
  SERVER_PASSWORD: "{{ vault_palworld_dedicated_server_server_password }}"  # Should be a string type
  PUBLIC_IP: "192.0.2.1"  # String type
  COMMUNITY_SERVER: false  # Boolean type
  GUILD_PLAYER_MAX_NUM: 20  # Integer type
  PAL_CAPTURE_RATE: 1.0  # Float type

These will be rendered as:

SERVER_NAME=Palworld Dedicated Server Ansible Collection
SERVER_PASSWORD=...
PUBLIC_IP=192.0.2.1
COMMUNITY_SERVER=false
GUILD_PLAYER_MAX_NUM=20
PAL_CAPTURE_RATE=1.000000

How-tos

Here are a few short guides for how to configure the collection for some commonly used setups.

Explicitly setting the service container names

By default, Docker Compose will automatically generate the names for the service containers (usually something along the lines of palworld-dedicated-server_<service-name>_1).

If you'd prefer to set the container names explicitly for each service, you can set them using the following variables (or set them to null for auto-generation):

palworld_dedicated_server_container_name: palworld-dedicated-server
palworld_dedicated_server_exporter_container_name: palworld-exporter

Enabling external access to the REST API

New in version 2.2.0.

Palworld (from version 0.2.0.6 onwards) now provides a REST API for managing dedicated servers. This provides more functionality and is easier to integrate with other applications than RCON.

In this Ansible collection, external access to the REST API port is disabled by default.

To enable external access to the REST API port, set the following inventory variable:

palworld_dedicated_server_api_enable: true

The external bind address and port can also be changed using the following variables (the below values are the defaults). To allow access from other hosts on the network, set palworld_dedicated_server_api_bind_address to 0.0.0.0.

palworld_dedicated_server_api_bind_address: "127.0.0.1"
palworld_dedicated_server_api_bind_port: 8212

When external access is enabled, the Ansible collection will make sure the port is accessible after the containers have been started. This operation has a default timeout of 10 minutes. If your Palworld server has a slow Internet connection and cannot download from Steam quickly, you may need to increase this value.

palworld_dedicated_server_api_wait_timeout: 600  # seconds

Enabling external access to RCON

Palworld dedicated servers can be managed by external applications using RCON.

In this Ansible collection, external access to the RCON port is disabled by default.

To enable external access to the RCON port, set the following inventory variable:

palworld_dedicated_server_rcon_enable: true

The external bind address and port can also be changed using the following variables (the below values are the defaults). To allow access from other hosts on the network, set palworld_dedicated_server_rcon_bind_address to 0.0.0.0.

palworld_dedicated_server_rcon_bind_address: "127.0.0.1"
palworld_dedicated_server_rcon_bind_port: 25575

When external access is enabled, the Ansible collection will make sure the port is accessible after the containers have been started. This operation has a default timeout of 10 minutes. If your Palworld server has a slow Internet connection and cannot download from Steam quickly, you may need to increase this value.

palworld_dedicated_server_rcon_wait_timeout: 600  # seconds

Enabling the Palworld Prometheus exporter

New in version 2.0.0.

A Prometheus exporter can optionally be orchestrated and run alongside your Palworld Dedicated Server, allowing for metrics to be collected by Prometheus, and further processed using tools like Grafana.

To enable the Prometheus exporter, set the following inventory variable:

palworld_dedicated_server_exporter_enable: true

By default, the Prometheus exporter listens to all interfaces on port 9877. The bind address and port can be overridden using the following variables:

palworld_dedicated_server_exporter_bind_address: "0.0.0.0"
palworld_dedicated_server_exporter_bind_port: 9877

Enabling the service user

New in version 2.1.0.

The Ansible collection can optionally create a service user and group for Palworld Dedicated Server to use.

This is more secure than the default configuration because it ensures that Palworld is run using a dedicated system user (with its own UID and GID), configured to only have access to resources it needs, and a no-login shell that forbids remote access. If any attacker breaks into the host system through a vulnerability in Palworld, they will be unable to do anything more than modify files owned by the service user.

Existing configurations (that do not currently use service users) can be converted to use service users simply by enabling the option and running the callum027.palworld_dedicated_server.update playbook.

To enable service users, set the following inventory variable:

palworld_dedicated_server_container_service_user_enable: true

By default, service users and groups have a unique UID/GID automatically assigned to them by the system.

If you wish to explicitly set the UID/GID for the service user/group, this may be done using the following inventory variables.

Make sure the values you set are not used by any other users/groups on the system.

palworld_dedicated_server_container_service_user_uid: 300
palworld_dedicated_server_container_service_group_gid: 300

By default, the service user and group are created using the name palworld. These can also be changed using inventory variables.

Make sure the values you set are not used by any other user/groups on the system.

palworld_dedicated_server_service_user_name: palworld
palworld_dedicated_server_service_group_name: palworld

Changing the container UID/GID without creating a service user

New in version 2.1.0.

To change the UID/GID that the service containers run as, without creating a full service user and group, set the following inventory variables.

The default container UID and GID are both set to 1000 by default.

palworld_dedicated_server_container_default_uid: 1000
palworld_dedicated_server_container_default_gid: 1000

Install mods into Palworld

Unfortunately this cannot be done automatically at the moment, for the following reasons:

Nexus Mods, the largest mod repository for Palworld, only allows downloads from logged in users, and limits the download speed for free users.
Mods are standardised to use the .pak file format, but the ZIP files they are contained in are not (some of them have convoluted file structures), making it difficult to automate installation.
Some mods require RE-UE4SS, which is not available for Linux.

Some mods, however, can be installed manually. Below is the procedure for doing so. If you have changed the install directory or service users/UIDs/GIDs in your installation, substitute them where /opt/palworld-dedicated-server and palworld are in the instructions below.

Copy all of the mod .pak files you wish to install to the dedicated server. This guide assumes they will be available from /home/<user>. If you access the server using SSH, the files can be copied using the scp command:
```
scp <mod-name>.pak <user>@<server-hostname>:/home/<user>/<mod-name>.pak
```
Temporarily stop the Palworld Dedicated Server, either using the callum027.palworld_dedicated_server.stop playbook, or running the following command:
```
sudo su -c 'cd /opt/palworld-dedicated-server && docker compose stop'
```

For each mod, install its corresponding .pak file to the Palworld .pak file directory:

sudo install --mode=755 --owner=palworld --group=palworld --target-directory=/opt/palworld-dedicated-server/data/Pal/Content/Paks /home/<user>/<mod-name>.pak

Restart the Palworld Dedicated Server, either using the callum027.palworld_dedicated_server.install playbook, or running the following command:
```
sudo su -c 'cd /opt/palworld-dedicated-server && docker compose up -d'
```

Make sure any mods installed on the dedicated server are also installed into your Palworld client installed locally.

Playbooks

The collection comes with a number of convenience playbooks for managing Palworld Dedicated Server from the command line.

To use them, make sure the hosts you wish to install Palworld Dedicated Server on are part of the palworld host group in the Ansible inventory.

`callum027.palworld_dedicated_server.install`

This playbook creates the files and directories for Palworld Dedicated Server, starts the server, and configures it to run on startup.

ansible-playbook -i <path to inventory> callum027.palworld_dedicated_server.install

Once the playbook has finished running, Palworld Dedicated Server will take a while to start as it downloads required service files from Steam. To keep an eye on this process, run the following command on the host (as a superuser, or user that is a member of the docker group) to look at the service logs:

cd /opt/palworld-dedicated-server && docker compose logs -f palworld-dedicated-server

`callum027.palworld_dedicated_server.update`

This playbook is similar to callum027.palworld_dedicated_server.install, except it will always update and recreate the Palworld Dedicated Server container image if there is an update available.

ansible-playbook -i <path to inventory> callum027.palworld_dedicated_server.update

`callum027.palworld_dedicated_server.restart`

This playbook restarts the Palworld Dedicated Service service container, without recreating it or modifying it in any way.

Useful when you want to update Palworld itself without touching anything else, as the container is configured to look for Palworld updates on startup by default.

ansible-playbook -i <path to inventory> callum027.palworld_dedicated_server.restart

Once the playbook has finished, keep an eye on Palworld update process using the following command on the host:

cd /opt/palworld-dedicated-server && docker compose logs -f palworld-dedicated-server

`callum027.palworld_dedicated_server.stop`

This temporarily stops the Palworld Dedicated Server service container, without destroying it or modifying it in any way.

Note that the service is still configured to launch on startup, so if the host reboots, the service will restart.

ansible-playbook -i <path to inventory> callum027.palworld_dedicated_server.stop

`callum027.palworld_dedicated_server.disable`

This stops the Palworld Dedicated Server service container, and deletes it so it cannot run on startup.

The container itself is immutable, and not modified while running. The Palworld save game data is stored on disk, so no data is lost in this operation.

ansible-playbook -i <path to inventory> callum027.palworld_dedicated_server.disable

`callum027.palworld_dedicated_server.uninstall`

This stops the Palworld Dedicated Server instance (if running), and completely removes all containers, and files related to Palworld Dedicated Server from the target hosts.

This playbook will irrecoverably remove Palworld Dedicated Server and the save data for the running game world. Make sure to backup any required data before running.

ansible-playbook -i <path to inventory> callum027.palworld_dedicated_server.uninstall

Roles

The following Ansible roles are provided. These roles perform the tasks run by the playbooks of the same name.

Using the roles directly allows you to run them on any host, or include them as part of another play.

callum027.palworld_dedicated_server.install
callum027.palworld_dedicated_server.update
callum027.palworld_dedicated_server.restart
callum027.palworld_dedicated_server.stop
callum027.palworld_dedicated_server.disable
callum027.palworld_dedicated_server.uninstall
