Apache Ignite Server to Client connection issues - server

Question

I have a Apache Ignite server installed on AWS EC2 instance. I'm using s3 bucket for client discovery. I have multiple micro-services deployed in docker container and they are communicating with Ignite server. The problem i'm into is, when my micro-service is registering it self to Ignite server as client, it is working perfectly fine. It is registering with docker containers private IP range, which is not accessible for Ignite server. Now when Ignite server is checking for client heartbeat, it is not able to reach. Can someone please tell what will be the best approach to use ignite with container based architecture.
output : while server trying to check client status
(wrn) <visor>: Failed to connect to node (is node still alive?). Make sure that each ComputeTask and cache Transaction has a timeout

Answer 1

1) Let ignite know the address of your EC2 ip
TcpDiscoverySpi spi = //whatever
spi.setLocalAddress( /* ip on ec2 subnet */ );
2) Run docker in "host" network mode, as opposed to the default "bridge" mode
These two steps should allow bidirectional TCP handshakes between the members of your Ignite cluster

Answer 2

You can forward host name to the ignite 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
