René's URL Explorer Experiment

It has to be directory, because device nodes come and go (hotplug). i.e. plug creates inode 1 -\u003e disconnect -\u003e plug creates inode 2. If you'd naively map `--device /dev/input/logitech` and start a container, during the whole lifecycle of the container it'd refer to inode 1.\r\n\r\nHere's my `/etc/udev/rules.d/80-screen-server.rules`:\r\n\r\n```\r\n# Logitech should be visible for screen-server\r\n\r\nACTION==\"add\", KERNEL==\"event[0-9]*\", ATTRS{name}==\"Logitech K400\", RUN+=\"/bin/sh -c 'mkdir -p /dev/input/screen-server \u0026\u0026 ln $devnode /dev/input/screen-server/logitech'\"\r\nACTION==\"remove\", KERNEL==\"event[0-9]*\", ATTRS{name}==\"Logitech K400\", RUN+=\"/bin/sh -c 'rm /dev/input/screen-server/logitech'\"\r\n```\r\n\r\nAnd docker-compose file:\r\n\r\n```yaml\r\nversion: \"3.5\"\r\nservices:\r\n  screens:\r\n    labels:\r\n      traefik.frontend.rule: Host:screens.mydomain.com\r\n    environment:\r\n      SCREEN_1: \"5900,800,1280,Galaxy Tab 2,/dev/input/screen-server/logitech\"\r\n    image: fn61/screen-server:20201218_1758_3beeef8d\r\n    shm_size: 512M # Firefox and Chrome crash on default (64 M) if website is heavy in any way\r\n    ports:\r\n      - \"5900:5900\"\r\n    devices:\r\n    - \"/dev/input/screen-server\"\r\n    networks:\r\n      default: null\r\nnetworks:\r\n  default:\r\n    external:\r\n      name: mynetwork\r\n```","author":{"url":"https://github.com/joonas-fi","@type":"Person","name":"joonas-fi"},"datePublished":"2021-04-03T11:19:35.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/2/screen-server/issues/2"}
