Docker services not reachable inside liunux cluster #1089

Open jfalameda opened 3 years ago

jfalameda commented 3 years ago

Hi,

I deployed an app with multiple docker services on a SF linux cluster via docker-compose. Although I specified the service name, aliases and hostname on the docker compose, I cannot reach those services (from other docker services) using DNS resolution. Why is this happening? How would service discovery work in this case?

patient.dhcloud:
    ...
    ports:
      - "5010:5010"
    hostname: patient.dhcloud
    networks:
       default:    
          aliases:
           - patient.dhcloud

I tried running the following example (https://github.com/Azure-Samples/service-fabric-containers/tree/master/Linux/container-dns-sample) with no results, the services cannot speak to each other.

I tried using a single-node, 3-node cluster both on Ubuntu 18 and Ubuntu 16 on Azure with no luck.

Are you using sfctl similar to the example and providing the dns name similar to the example? "--dns-name pythonbackend.simplecontainerapp" from https://github.com/Azure-Samples/service-fabric-containers/blob/master/Linux/container-dns-sample/install.sh
