# Production environment resource requirements

If you deploy Hwameistor in a production environment, please specify the resource configuration and avoid deploying it on the Master node. Therefore, some recommended values are provided in the `values.extra.prod.yaml` file. The resource configuration is as follows:

1. If it is created through Helm, it can be created in the following way:

    ```console
    helm install hwameistor ./hwameistor \
        -n hwameistor --create-namespace \
        -f ./hwameistor/values.yaml \
        -f ./hwameistor/values.extra.prod.yaml
    ```

2. If installing through the UI interface, please manually configure the above resources
   through the Resource value in YAML, otherwise it will not be configured by default:
