I'm using Apache Ignite .Net v2.7. While resolving another issue (How to use TcpDiscoveryKubernetesIpFinder in Apache Ignite .Net) I've added a sprint configuration file where the Kubernetes configuration is specified. All other configuration goes in the C# code.
The content of the config file is below (taken from the docs):
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/util
http://www.springframework.org/schema/util/spring-util.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">
<property name="namespace" value="ignite"/>
</bean>
</property>
</bean>
</property>
</bean>
</beans>
The C# code which references the file is as follows:
var igniteConfig = new IgniteConfiguration
{
SpringConfigUrl = "./kubernetes.config",
JvmClasspath = string.Join(";",
new string[] {
"ignite-kubernetes-2.7.0.jar",
"jackson-core-2.9.6.jar",
"jackson-databind-2.9.6.jar"
}
.Select(c => System.IO.Path.Combine(Environment.CurrentDirectory, "Libs", c)))}
The Ignite node starts fine locally but when deployed to a Kubernetes cluster, it fails with this error:

Do you have any idea why it might happen? Which logger is it complaining about?
Kubernetes is running Linux containers, locally I'm using Windows 10.
Two more observations:
When I specify the config file name as
kubernetes.config, the node launches successfully on local but in Kubernetes it fails with an error which suggests that the URL "kubernetes.config" is missing the schema part.JvmClasspath: I have to add "ignite-kubernetes-2.7.0.jar", otherwise the JAR is not found although it is located in the same dir as the rest of the Ignite classes. Adding the next two entries does not make any difference.
