Docker swarm worker service unable to access service on manager
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty height:90px;width:728px;box-sizing:border-box;
I have a single node docker Swarm. I deployed a stack with Influxdb (placement: manager), Grafana (placement: manager) and cAdvisor (deploy mode global).
I use Portainer to visualize the stack. And it correctly shows 1 manager node with its services.
Then I added a second (worker) node with docker swarm join etc...
Now the cAdvisor service is also launched on the worker, but it has a problem, it keeps logging:
E1115 14:52:46.772290 1 memory.go:91] failed to write stats to influxDb - Post http://influx:8086/write?consistency=&db=cadvisor&precision=&rp=: dial tcp: lookup influx on 127.0.0.11:53: no such host
Any ideas?
Thanx

Did you open the required ports for communication between the manager and workers? docs.docker.com/engine/swarm/swarm-tutorial/…

Yes. And I created an overlay network (of course). Services are all attached to same network
