• Caddy starts with a regular conf but without routes:

  json
  1{
  2  "apps": {
  3    "http": {
  4      "servers": {
  5        "myserver": {
  6          "automatic_https": {
  7            "skip": []
  8          },
  9          "listen": [
  10            ":443"
  11          ],
  12          "routes": [
  13          ]
  14        }
  15      }
  16    }
  17  }
  18}

• This gRPC server is started.
• Each application uses this server by sending requests to register their routes via gRPC calls.

• Arranging OpenStreetMap Map Tiles
  • The resulting tiles are suitable for printing
  • Producing a big PNG-file made of tiles
