how to create multiple clusters in one helm deployment

[amanda45762]

Hi,
How can I create multiple clusters (e.g. one named 'test_cache_1' and one named 'test_cache_2') on the same k8s statefulset nodes (meaning one helm deployment). Is there a way to use multiple different hazelcast.yaml configuration files in one deployment? I have a lot of logical groups (clusters) and don't want to have to deploy a whole different statefulset per cluster.

I see it is possible to have multiple clusters/instances in one JVM based on the docs here https://docs.hazelcast.com/hazelcast/5.5/clusters/creating-clusters

Is this newHazelcastInstance method exposed anywhere except java? Seems strange that we would have to write a custom wrapper to start multiple instances on the same jvm, instead of using the default hazelcast jar. https://github.com/hazelcast/hazelcast/blob/master/hazelcast/src/main/java/com/hazelcast/core/Hazelcast.java#L60

this example looks as close as I'm going to get to exposing the newHazelcastInstance method: https://github.com/hazelcast/hazelcast-code-samples/blob/master/clients/user-code-deployment/user-code-deployment-member/src/main/java/Member.java
