Ignite cluster on kuberntes

12/17/2020

I have build on one kuberntes vm 2 pods of ignite - and when I check state everything looks fine but it isn't working fine on kuberntes cluster

I set discoveryIP as you can see attached as well can you suggest why? and what can be done?

    <!-- Explicitly configure TCP discovery SPI to provide list of initial nodes. -->
    <property name="discoverySpi">
        <bean class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi">
            <property name="ipFinder">
                <!--
                    Enables Kubernetes IP finder and setting custom namespace and service names.
                -->
                <bean class="org.apache.ignite.spi.discovery.tcp.ipfinder.kubernetes.TcpDiscoveryKubernetesIpFinder">
                    <property name="namespace" value="production"/>
                    <property name="serviceName" value="{{ include "ignite.fullname" . }}"/>
                </bean>
            </property>
        </bean>
    </property>
</bean>

</beans>

shard logs and status below.

> Cluster  ID: 0d910f16-fc9e-4837-b502-eecd100c530e Cluster tag:
> loving_lovelace
> -------------------------------------------------------------------------------- Cluster is active Command [STATE] finished with code: 0 Control
> utility has completed execution at: 2020-12-17T08:20:26.317

however when I deploy the exact same chart on cluster I recived the following errors:

Failed to activate cluster.
Connection to cluster failed. Latest topology update failed.
Execution time: 33284 ms
command terminated with exit code 2

and in logs:

Well, from the error, it seems that the default K8s service is not working or probably doesn't exist:

Caused by: java.net.UnknownHostException: kubernetes.default.svc.cluster.local

Please, check the following documentation: https://apacheignite.readme.io/docs/kubernetes-ip-finder. By default Kubernetes IP Finder tries to reach the "/kubernetes.default.svc.cluster.local:443" that might not be true in your case. I think you need to check your URL and adjust the parameter:

setMasterUrl(String) Sets the host name of the Kubernetes API server. https://kubernetes.default.svc.cluster.local:443

Could you also add some notes about your deployment or k8s version to the question?
