Shepherd

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.
