hi @Lebowski89, thank you for sharing this. Unfortunately I don't have a cluster of docker servers.
np, thank you for your blog. I just thought, if you wanted to install docker on your raspberry pi, you could make it a docker swarm worker and use your main server to deploy technitium to it. I've never owned a rpi, though, so not sure if installing docker on them has issues. Using a Beelink Mini-PC as a Swarm worker for the second Technitium instance.
