Thalita Vergilio created FLINK-7961:
---------------------------------------
Summary: Docker-Flink with Docker Swarm doesn't work when machines
are in different clouds
Key: FLINK-7961
URL: https://issues.apache.org/jira/browse/FLINK-7961
Project: Flink
Issue Type: Bug
Components: Docker
Affects Versions: 1.3.0
Reporter: Thalita Vergilio
Priority: Normal
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:
