i am trying to connect my docker services together in docker swarm.
the network is made of 2 raspberry pi’s.
i can create an overlay network called test-overlay and i can see that services on either raspberry pi node can connect to the network.
my problem:
i cannot link to services between nodes with the overlay network.
given the following configuration of nodes and services, service1 can use the address http://service2 to connect to service2. but it does NOT work for http://service3. however http://service3 is accessible from service4.
node1:
- service1
- service2
node2:
- service3
- service4
i am new to docker swarm and any help is appreciated.
