Is there anyone using mailcow with swarm/stacks? If you do, which volume driver are you using?
No it’s a huge thing to create a mailcow cluster.
You would need to rewrite netfilter, IPv6 NAT and so on. You can’t just start multiple container somewhere and call it a cluster.
If you have a shared storage then it’s a a bit easier.
Oh, I see. So mailcow uses docker but it’s not made to be run on a docker cluster. Thanks Magic!
As it’s open-source, feel free to contribute necessary changes in a PR on GitHub 🙂
