How do you route stuff through your swarm? Using the mesh comes with quiet the performance penalty. It just sprays requests all over the swarm and does masses of unnecessary round trips.
My current approach is to publish my servcies ports in
mode: host and have a
deploy.mode: global instance of traefik running on every node, favoring the service on the same host over fallback to all other nodes. I can easily “discover” the services by using healthchecks. My services are quiet small and static. It’s just like 5 published ports in a stack. So I don’t mind configuring them static.
I would basically just use swarm for orchestration and build the overlay network myself.
Maybe it would be possible to get the info which node is running which service from the docker.sock and update traefik config accordingly. But other than one http request every ten seconds, I don’t see a big downside on just using healthchecks to do the same thing.
Interested to hear how you deal with things.
