Hi All, I'm now implementing a membership scheme for Kubernetes for enabling Hazelcast cluster discovery for Carbon products on Kubernetes (K8S).
We recently did a modification in Carbon Core for allowing users to plug in membership schemes without having to modify the Kernel. This is now available for Carbon 4.2.0 based products with Kernel patch0012 and Carbon 4.4.2 based products OOB. *How it works* In K8S we use K8S services for load balancing container clusters. K8S services use nginx internally. These services can be used for identifying the list of members in a given cluster. Similar to the AWS and Private PaaS membership schemes, the new K8D membership scheme is being implemented to add all existing members of the cluster to Hazelcast network config before the Hazelcast instance is initialized. This would happen automatically whenever a carbon server is started. This design would make sure all the members in the cluster are connected to all the other members. As a result we will be able to scale the cluster up and down on K8S without affecting clustering configuration.
