             Summary: Configuring sticky LoadBalancer for Ignite Service with Kubernetes
                 Key: IGNITE-8993
                 URL: https://issues.apache.org/jira/browse/IGNITE-8993
             Project: Ignite
          Issue Type: Task
          Components: documentation
            Reporter: Denis Magda
             Fix For: 2.7


Ignite service used for Ignite pods auto-discovery and access to the cluster from remote applications
is deployed as LoadBalancer:
https://apacheignite.readme.io/docs/ignite-service

This might lead to problems when a stateful session is needed between an app and the cluster.
For instance, Ignite JDBC driver preserves the state of an opened connection meaning that
once LoadBalancer connects the driver to an Ignite pod, all the queries have to be redirected
to that Ignite pod only (unless the pod is down).

We need to show how to configure a sticky LoadBalancer that will assign a client connection
to a specific pod and won't change it.
