Answer 1

You can forward 1st container's host name to the ignite node of 2nd container via a system environment variable in your ignite configuration:

<bean class="org.apache.ignite.spi.discovery.tcp.ipfinder.vm.TcpDiscoveryVmIpFinder">
    <property name="addresses">
        <list>
            <value>#{systemEnvironment['IGNITE_HOST'] ?: '127.0.0.1'}:47500..47509</value>
        </list>
    </property>
</bean>

An example of docker-compose.yml for 2 communicated ignite services:

version: "3"
services:
  ignite:
    image: image_name1
    networks:
      - net
  face:
    image: image_name2
    depends_on:
      - ignite
    networks:
      - net
    environment:
      IGNITE_HOST: 'ignite'

The ignite node of 'face' can connect to the another ignite node of 'ignite' using the address ignite:47500..47509
