Traefik on docker worker node isolated to cluster

Traefik Traefik v2
1

Hello,

I'm trying traefik on swarm and all works well, except one case, workers isolated

Traefik and services are deployed on all my nodes (managers + workers) and I'm using docker-socket-proxy on manager to check the socket docker

Unfortunately when a worker is isolated , traefik returns "bad gateway" randomly, I guess it tries to access to the service on manager and right after locally

So my question is, there is a way on workers to "remove" the unreachable distant service ?

To be more clear

If I have a manager with an http website and a worker with exactly the same website balanced by traefik on each ( and round robin DNS) I can do something if my manager is down ?

Thanks

With a swarm you should have at least 3 managers for HA to avoid this situation. 5 if you want to survive more than 1 manager being offline.

Yes I known, maybe I'm not clear my question is only about an isolate node, the node still have traefik and a container (with website) running

Thank you

It's too bad, because in this case it almost working, traefik redirects to local and another workers/managers, so from users point of view, it works, don't works, works, etc, in short it works randomly

Right you either need a loadbalancer before that or some adaptive dns or a GTM to manage that.

could you fix it?

... for me, it sounds, like it "round-robins" / iterates through your distributed instances/replicas on different nodes ...

I had the same problem (with one master and two worker-nodes)
