Can you elaborate on its issues? I've never used it on production myself, but it looks like a simplified k8n, which is something I feel a lot of people desire

Last used it years ago, networking would just die randomly, requiring container restarts when using multiple nodes

I have heard (though haven't tried) that V2 of Compose/Swarm is significantly better.

Anything can and will break. Symptomatically similar thing happened to me with K8s with (IIRC) Calico. And I’ve had issues with Swarm too, although of a different kind (it quietly refused to run a data channel for me over an IPv6-only network, while control channel worked just fine).

It was all quite a while (3-4 years) ago, so I don’t remember much details, except that Swarm was then not exactly capable of working in IPv6-only environments. It was significantly easier to navigate Docker’s codebase than Kubernetes’.

(Ultimately, my solution was that I understood that I didn’t need any kind of orchestration there, just HA/failover. But that’s another story.)

I haven’t used it for many years but in short it just didn’t work reliably. I mostly encountered network iptables issues from memory.

I've been very happy with until now, though i must admit i'm using one node swarms. But i'd rather use that (1) than sticking together a custom solution using docker compose as i see it mentioned sometimes.

Infinite issues with overlay networking once you scale past 30 nodes in a swarm. Weave aside, network drivers for anything not CNI are basically deprecated/dead.
