 Summary: Docker-Flink: TaskManagers can't find JobManager when in 
different nodes in Docker Swarm
 Key: FLINK-7965
 URL: https://issues.apache.org/jira/browse/FLINK-7965
 Project: Flink
  Issue Type: Bug
  Components: Docker
Affects Versions: 1.3.2
 Environment: node: ubuntu-swarm-master
Azure VM Standard D4s v3 (4 vcpus, 16 GB memory)
Docker version 17.03.1-ce, build c6d412e

node: azure-swarm-worker-1
Azure VM Standard D2 v2 Promo (2 vcpus, 7 GB memory)
Docker version 17.09.0-ce, build afdb6d4

Flink: using image 1.3.2-hadoop2-scala_2.10
Reporter: Thalita Vergilio
Priority: Major


This happens even when the nodes are in the same subnet.

I am using the Docker-Flink project in: 
https://github.com/apache/flink/tree/master/flink-contrib/docker-flink

I am creating the services with the following commands: 
docker network create -d overlay overlay 
docker service create --name jobmanager --env 
JOB_MANAGER_RPC_ADDRESS=jobmanager -p 8081:8081 --network overlay --constraint 
'node.hostname == ubuntu-swarm-manager' flink jobmanager 
docker service create --name taskmanager --env 
JOB_MANAGER_RPC_ADDRESS=jobmanager --network overlay --constraint 
'node.hostname != ubuntu-swarm-manager' flink taskmanager 

I wonder if there's any configuration I'm missing. This is the error I get: 
- Trying to register at JobManager akka.tcp://flink@jobmanager:6123/   
user/jobmanager (attempt 4, timeout: 4000 milliseconds)

Task Managers can't find Job Manager by name. Maybe some additional Docker 
configuration is needed?

I am running the standard setup and create-docker-swarm-service.sh script from 
the Docker Flink project:
https://github.com/apache/flink/blob/master/flink-contrib/docker-flink/create-docker-swarm-service.sh

This is the log from one of the Task Manager's containers:
