Had to do hacky work-arounds using the configmaps since they are read-only and I didn't want a separate config.ini file

kind: ConfigMap
apiVersion: v1
metadata:
  name: openrct2-config
data:
  config.ini: |
    [general]
    show_fps = true
    currency_format = USD
    date_format = MM/DD/YY
    language = en-US
    temperature_format = FAHRENHEIT
    measurement_format = IMPERIAL
    auto_open_shops = true
    show_guest_purchases = true

    [network]
    player_name = "Player"
    advertise = true
    default_port = 11753
    maxplayers = 8
    server_name = "Kubernetes Playground"
    server_description = "Kubernetes Hosted"
    server_greeting = "Welcome!"
