loki.fullnamewill not be available unless Loki is deployed at the same time as Traction.I think it might be best to just use a full URL from the values file in case Loki is not being deployed with the solution. Otherwise you'll have to add Loki as a dependent chart to Traction and handle on/off scenarios.
