Use c2casgiutils route_prefix instead of tilecloud-chain's own - #3798
Merged
Conversation
Replace TILECLOUD_CHAIN__ROUTE_PREFIX with C2C__ROUTE_PREFIX (from c2casgiutils) for the route prefix environment variable. Remove the duplicate _to_route_prefix validator and RoutePrefix type from tilecloud_chain.settings. Add C2C__ROUTE_PREFIX=/tiles/ in the Dockerfile to preserve the existing default behavior.

Summary
Replace tilecloud-chain's own
route_prefixsetting with the one provided by c2casgiutils (C2C__ROUTE_PREFIX), eliminating duplicated configuration and validation logic.Context
tilecloud-chain defined its own
route_prefixsetting (TILECLOUD_CHAIN__ROUTE_PREFIX, default/tiles/) with a custom validator, while c2casgiutils already provides an equivalentroute_prefixsetting (C2C__ROUTE_PREFIX, default/) with identical normalization logic. This PR removes the duplication.Implementation Details
