of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.

You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.

5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the

other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.

and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf

# Palworld Helm Chart

This chart installs [docker-palworld-dedicated-server](https://github.com/jammsen/docker-palworld-dedicated-server) on a [Kubernetes](http://kubernetes.io/) cluster using the [Helm](https://helm.sh/) package manager.

## Usage

[Helm](https://helm.sh) must be installed to use the charts. Please refer to
Helm's [documentation](https://helm.sh/docs) to get started.

Once Helm has been set up correctly, add the repo as follows:

```sh
helm repo add caleb-devops https://caleb-devops.github.io/helm-charts
```

If you had already added this repo earlier, run `helm repo update` to retrieve
the latest versions of the packages. You can then run `helm search repo
caleb-devops` to see the charts.

To install the palworld chart:

```sh
helm install palworld caleb-devops/palworld
```

To upgrade the palworld chart:

```sh
helm upgrade palworld caleb-devops/palworld
```

To uninstall the chart:

```sh
helm uninstall palworld
```

## Configuration

See [Customizing the Chart Before Installing](https://helm.sh/docs/intro/using_helm/#customizing-the-chart-before-installing). To see all configurable options with detailed comments, visit the chart's [values.yaml](./values.yaml).

### Networking

This Chart uses a [LoadBalancer Service](https://kubernetes.io/docs/concepts/services-networking/service/#loadbalancer) to expose the application outside Kubernetes:

```yaml
service:
type: LoadBalancer
## Example annotations for kube-vip or MetalLB to assign an IP to the LoadBalancer
annotations: {}
# kube-vip.io/loadbalancerIPs: 192.168.1.100
# metallb.universe.tf/loadBalancerIPs: 192.168.1.100
port: 8211
```

Note: Port-Forwarding may be required if the LoadBalancer does not use a Public IP.

### Persistent Volume

Data persistance is enabled by default using dynamic volume provisioning.

> [!WARNING]
> Set the configured storageClass [reclaim policy](https://kubernetes.io/docs/concepts/storage/storage-classes/#reclaim-policy) to `Retain` to prevent automatic deletion of the PV if the chart is uninstalled.
### Palworld Config

To configure the server, add the [environment variables](https://github.com/jammsen/docker-palworld-dedicated-server/blob/develop/docs/ENV_VARS.md) to `config`:

```yaml
config:
env:
TZ: UTC # Timezone used for time stamping server backups
ALWAYS_UPDATE_ON_START: true
MULTITHREAD_ENABLED: true
COMMUNITY_SERVER: false
BACKUP_ENABLED: true
BACKUP_CRON_EXPRESSION: "0 * * * *" # Backup every hour
BACKUP_RETENTION_POLICY: true # Cleanup old backups
BACKUP_RETENTION_AMOUNT_TO_KEEP: 168 # Retain backups for 7 days
SERVER_SETTINGS_MODE: auto # Apply game settings using environment variables
SERVER_NAME: "Default Palworld Server"
SERVER_DESCRIPTION: ""
MAX_PLAYERS: 32
PUBLIC_IP: ""
PUBLIC_PORT: 8211

secretEnv:
create: true
env:
SERVER_PASSWORD: "serverPasswordHere"
ADMIN_PASSWORD: "adminPasswordHere"
```

### Prometheus Exporter

This chart supports exporting Prometheus metrics with [palworld-exporter](https://github.com/palworldlol/palworld-exporter). To enable metrics, set the following values:

```yaml
metrics:
enabled: true

serviceMonitor:
## Create Prometheus Operator ServiceMonitor resource
enabled: true

## Additional environment variables used to configure palworld-exporter
## ref: https://github.com/palworldlol/palworld-exporter/tree/main?tab=readme-ov-file#options
##
env:
## Path to your Palworld save directory
SAVE_DIRECTORY: /palworld/Pal/Saved/SaveGames/0/XXXXX.../
```

> [!NOTE]
> RCON must be enabled to use palworld-exporter.
See the [palworld-exporter documentation](https://github.com/palworldlol/palworld-exporter) for additional details and an example Grafana dashboard.
