How and where to put the params path to calling URL


I’ve an application ( karaf ) who need to call the same URL(mobd-api.corp) with different path .

ds-ap-service https://mobd-api.corp/ap
ds-ids-service https://mobd-api.corp/ids
ds-chat-service https://mobd-api.corp/chat

My problem is i dont know how and where to set the different path. Do i’ve to do it in pod.yaml or do i’ve to create an ingress ?
Do you think it’s a good idea to create a PV, PVC for all the configs files that i’ve ? around 10 files
