Shared memeory size parameter with Synology Docker variant #387

Open gsontheimer opened 1 year ago

gsontheimer commented 1 year ago

When running Docker containers of openstreetmap-tile-server on my PC I can use the --shm-size parameter to increase the shared memory size.

The Synology implementation of Docker does not allow to pass parameters at run time (at least I have found no way).

Is there a way to use environment varaibles to achieve the same purpose? could the code be changed so that environment variables could set the size of the shared memory?

No, this is not possible via environment variables, because this is a setting outside of the control of the docker container.

This seems to be a workaround: https://github.com/jlesage/docker-firefox/issues/16#issuecomment-744742817

Besides that if you can't control it, you could change the postgres configuration to lower the default setting for shared memory of 128M to below 64M (docker default).

Since the release of DSM 7.2, Docker has introduced new features. Within the Container Manager, users can now input a YAML configuration for Docker Compose under the "Projects" section. This configuration is used to build the container. Attached is an example where the SHM (shared memory) is configured to 512MB.

version: '3.7'

services:
  map:
    image: overv/openstreetmap-tile-server
    volumes:
      - /volume2/docker/osm/database:/data/database/
      - /volume2/docker/osm/tiles:/data/tiles/
    ports:
      - "8123:80"
    command: "run"
    shm_size: 512m
