use shepherd to update images

Update Swarm Images

i wanted to update swarm images whenever there is a new image available (even at the risk of breaking something)

it seems watchtower can't do this for swarm stacks/services - only one off containers.

I found this great container from https://github.com/djmaze/shepherd

placement considerations

Must be placed on a manager node.

Config notes

By default it will refresh all services, exclude any you dont want it to touch. I am not using apprise for this yet, but will be implementin apprise soon.

version: "3"
services:
  shepherd:
    build: .
    image: mazzolino/shepherd

      - SLEEP_TIME=60m
      - IGNORELIST_SERVICES="shepherd_shepherd wordpress_db wordpress_wordpress"

      - TZ=America/Los_Angeles
      - IMAGE_AUTOCLEAN_LIMIT=2
#      - APPRISE_SIDECAR_URL=apprise-microservice:5000      	
    volumes:

Because watchtower doesn't work on services, only containers. Get Outlook for iOS<https://aka.ms/o0ukef>
