XYZ Tile Cache

A slippy (xyz) tile proxy server that caches tiles for fast local retrieval or offline loading.

Bounding boxes with max zoom levels can be defined for preloading tile data. If a tile is not locally available the server will reach out to the source to try and retrieve the tile. If successful the new tile will be cached as long as the maxTileStorage has not been surpassed.

Configuration Parameters

server:
  port: 8383

xyz:
  baseTileDirectory: "/tmp/tiles"
  maxTileStorage: 1000000000
  layers:
    - name: "satellite"
      urlTemplate: "http://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer/tile/{z}/{y}/{x}"
  boundingBoxes:
    - preCache: true
      maxZoom: 5
      north: 70
      south: -70
      east: 179
      west: -179

Docker Build

docker build . -t xyz-tile-cache:latest

Docker Run

This example assumes a local tile repository at /tmp/tiles and a configuration file at /tmp/application.yml

docker run -v /tmp/tiles:/tmp/tiles -v /tmp/application.yml:/app/application.yml --rm --name xyz -p 127.0.0.1:8383:8383/tcp xyz-tile-cache:latest

By default tile layers will be available at http://localhost:8383/tilesZYX/satellite/{z}/{y}/{x}.png
