Can not connect Apache Ignite on Azure Kuberntes from .net core app
I am new to Ignite and Kubernetes. I have a.Net Core 3.1 web application which is hosted Azure Linux App Service.
I followed the instructions (Apache Ignite Instructions Offical Site) and Apache Ignite could run on Azure Kubernetes. I could create a sample table and read-write actions worked successfully. Here is the screenshot of my success tests on PowerShell.
Now, I try to connect Apache Ignite from my .net core web app but I couldn't make it. My code is as below. I try to connect with IgniteConfiguration and SpringCfgXml, but both of them getting error.
private void Initialize()
{
var cfg = GetIgniteConfiguration();
_ignite = Ignition.Start(cfg);
InitializeCaches();
}
public IgniteConfiguration GetIgniteConfiguration()
{
var appSettingsJson = AppSettingsJson.GetAppSettings();
var igniteNodes = appSettingsJson["AppSettings:IgniteNodes"];
var nodeList = igniteNodes.Split(",");
var config = new IgniteConfiguration
{
Logger = new IgniteLogger(),
DiscoverySpi = new TcpDiscoverySpi
{
IpFinder = new TcpDiscoveryStaticIpFinder
{
Endpoints = nodeList
},
SocketTimeout = TimeSpan.FromSeconds(5)
},
IncludedEventTypes = EventType.CacheAll,
CacheConfiguration = GetCacheConfiguration()
};
return config;
}
The first error I get:
Apache.Ignite.Core.Common.IgniteException HResult=0x80131500
Message=Java class is not found (did you set IGNITE_HOME environment variable?): org/apache/ignite/internal/processors/platform/PlatformIgnition
Source=Apache.Ignite.Core
Also, I have no idea what I am gonna set for IGNITE_HOME, and username and secret to authentication.

The simplest way is to download Apache Ignite binary distribution (of the same version as one that you use), unzip it to a directory, and point IGNITE_HOME environment variable or IgniteConfiguration.IgniteHome configuration property to unzipped apache-ignite-n.n.n-bin/ directory absolute path.
We support doing that automatically for Windows-hosted apps but not for Linux-based deployments.
Solution : I finally connect the Ignite on Azure Kubernetes.
Here is my connection method.
public void TestConnection()
{
var cfg = new IgniteClientConfiguration
{
Host = "MyHost",
Port = 10800,
UserName = "user",
Password = "password"
};
using (IIgniteClient client = Ignition.StartClient(cfg))
{
var employeeCache1 = client.GetOrCreateCache<int, Employee>(
new CacheClientConfiguration(EmployeeCacheName, typeof(Employee)));
employeeCache1.Put(1, new Employee("Bilge Wilson", 12500, 1));
}
}
To find to host IP, user name and client secret please check the below images.

Note: I don't need to set any IGNITE_HOME ana JAVA_HOME variable.
