Apache Ignite Thin Client is not connect to AKS

Question

I created an AKS and I deployed the Apache Ignite service on it. When I check the pods I can see they are working.

Also, I can get the load balancer IP.

I follow the official instructions of Apache and try to connect Ignite with ThinClient. I share my code and instructions code.

Here is my code:

public void ConnectIgnite()
{
    var cfg = new IgniteClientConfiguration
    {
       Endpoints = new[] { "20.101.12.***:10800" }
    };
    
    var client = Ignition.StartClient(cfg);
}

But my code is getting below errors;

System.AggregateException: 'Failed to establish Ignite thin client connection, examine inner exceptions for details.'

Inner Exception ExtendedSocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

and here is the Apache's instruction code;

ClientConfiguration cfg = new ClientConfiguration().setAddresses("13.86.186.145:10800");
IgniteClient client = Ignition.startClient(cfg);

ClientCache<Integer, String> cache = client.getOrCreateCache("test_cache");

cache.put(1, "first test value");

System.out.println(cache.get(1));

client.close();

Also, here is the official instruction link

I didn't understand what is wrong? Also, The Instruction says I don't need clientid and clientsecret but I don't want to connect without any security but this is completely another issue.

I found what is wrong. Apache's official page says: use below XML for the configuration.

<bean class="org.apache.ignite.configuration.IgniteConfiguration">

    <property name="discoverySpi">
        <bean class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi">
            <property name="ipFinder">
                <bean class="org.apache.ignite.spi.discovery.tcp.ipfinder.kubernetes.TcpDiscoveryKubernetesIpFinder">
                    <constructor-arg>
                        <bean class="org.apache.ignite.kubernetes.configuration.KubernetesConnectionConfiguration">
                            <property name="namespace" value="default" />
                            <property name="serviceName" value="ignite" />
                        </bean>
                    </constructor-arg>
                </bean>
            </property>
        </bean>
    </property>
</bean>

but,

first, that XML needs a beans tag at the top of XML. Also, namespace value and serviceName value are not compatible with apache's official instruction page. If you follow the apache's page for the setup;

you have to use the below values

<property name="namespace" value="ignite" />
<property name="serviceName" value="ignite-service" />

instead of

<property name="namespace" value="default" />
<property name="serviceName" value="ignite" />

end of the changes your XML will look like

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd">
    <bean class="org.apache.ignite.configuration.IgniteConfiguration">
        <property name="discoverySpi">
            <bean class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi">
                <property name="ipFinder">
                    <bean class="org.apache.ignite.spi.discovery.tcp.ipfinder.kubernetes.TcpDiscoveryKubernetesIpFinder">
                        <constructor-arg>
                            <bean class="org.apache.ignite.kubernetes.configuration.KubernetesConnectionConfiguration">
                                <property name="namespace" value="ignite" />
                                <property name="serviceName" value="ignite-service" />
                            </bean>
                        </constructor-arg>
                    </bean>
                </property>
            </bean>
        </property>
    </bean>
</beans>

I changed my configuration XML and restart the pods with below command and It worked.

kubectl -n service rollout restart deployment ignite-cluster

Try connecting using 20.101.12.*** address from the outside. Btw, what is 13.86.186.145, why are you trying to connect to it?

An update: Seems like you just copy-pasted it from the docs, you need to replace it with your own values.

Also, if you just testing something with Ignite, you might go with GridGain Operator which simplifies installation a lot from my experience https://www.gridgain.com/docs/latest/installation-guide/operator/quick-start – Alexandr Shapkin Jul 29 '21 at 11:28
I'm not connecting to 13.86.186.145. That code is apache's sample code. Mine is above. My IP starts with 20 – OguzKaanAkyalcin Jul 29 '21 at 11:38
Hi Alexandr, I answered the question. Could you check it and if it's right please vote it. – OguzKaanAkyalcin Aug 03 '21 at 11:46
Hi, yes, there has to be something simple, I think you are right. – Alexandr Shapkin Aug 03 '21 at 16:14
Btw, I was thinking that the author could mark it as correct one with the green button. – Alexandr Shapkin Aug 03 '21 at 16:15
