Hi Krzysztof, Xintong has share some information about the configuration. I just want to provide some additional information.
>> How JobManager and TaskManager find each other? For non-HA Flink cluster, the taskmanager should have the pre-configured jobmanager address. For HA Flink cluster, the leader retriever service is used for taskmanager to get the jobmanager address. Currently, Flink provide the zookeeper implementation. And it has been widely used in production. >> Can it be configure to use domain names instead IP's? It could be a domain name. But you should make sure the it could be resolved by other jobmanager/ taskmanagers. >> What I have to do to have two Flink Clusters in same IP network? I am not sure what do you mean. Do you mean you have a NAT network and multiple docker containers will share a internal ip address? >> How I should start task manager in order to tell him, to connect to cluster B not A? Just like i have said in the first section. For non-HA Flink cluster, you need to specify the jobmanager rpc address and port. For HA Flink cluster, you do not need to do anything.
