Remote Docker Host not monitored

[marcolino7]

Hi, I have 3 docker host in my homelab. One of them run WUD, and accessed via local file. Other two are accessed via tcp socket without encryption. Here is config:

version: '3'
services:
  whatsupdocker:
    image: fmartinou/whats-up-docker
    container_name: Whats-Up-Docker
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /volume1/docker/whats-up-docker:/store
    ports:
      - 3000:3000
    environment:
      - TZ=Europe/Rome
      - WUD_WATCHER_SYNOLOGY_SOCKET=/var/run/docker.sock
      - WUD_WATCHER_SYNOLOGY_CRON=10 9 * * *
      - WUD_WATCHER_DOCKER1_HOST=192.168.99.74
      - WUD_WATCHER_DOCKER1_CRON=11 9 * * *
      - WUD_WATCHER_SURVIVAL_HOST=192.168.99.63
      - WUD_WATCHER_SURVIVAL_CRON=12 9 * * *
      - WUD_TRIGGER_PUSHOVER_1_TOKEN=------MY TOKEN------
      - WUD_TRIGGER_PUSHOVER_1_USER=--------MY USER--------
      - WUD_TRIGGER_PUSHOVER_1_SIMPLEBODY=Container $${name} running on $${watcher} have an update available \n
      - WUD_TRIGGER_PUSHOVER_1_PRIORITY=0
      - WUD_TRIGGER_PUSHOVER_1_MODE=batch
      - WUD_TRIGGER_PUSHOVER_1_ONCE=false

When Cron start, I receive notification on SYNOLOGY, the docker.sock one. On other 2 host, there is container that have not an image in docker Hob and raise an error, but other valid container are not checked:

09:10:00.848  INFO whats-up-docker/watcher.docker.synology: Cron started (10 9 * * *)

09:12:01.647  INFO whats-up-docker/watcher.docker.survival: Cron finished (0 containers watched, 0 errors, 0 available updates)

On host docker1 there are container with valid image on dockerhub, but i get.docker1: Cron finished (0 containers watched, 0 errors, 0 available updates), and also for host survival.

I hope I miss something, but I cannot understand what.

Thanks in advance

those error messages, especially the authorized part, read to me like your remote docker daemon requires authentication. Are you sure, you set that up correctly without encryption on your remotes?

Can you connect using docker -H=192.168.99.74:2376 version ?

Also the default port set by WUD is 2375, did you setup your docker remotes on this port, too? The docker documentation recommends port 2376, that's why I'm asking.
