v300 Cluster example

[Tochemey]

Hello,

I would like to know whether there is an example on how to use ergo in cluster mode using kubernetes, NATs and co.

Hi @Tochemey ,

not sure if i follow your question about the kubernetes. nothing can stop you to start your cluster under the kuber-umbrella. Ergo Framework has service discovery feature embedded. But you may use "Saturn" central registrar as well. It provides you advanced features beside of the nodes registration/discovering - you can subscribe to the registrar events to receive the cluster events (node join/leave, app start/stop). Additionally it provides configuration management feature to broadcast any cluster configuration change on the fly.

for the basic pub/sub you can use "Events" feature of the Ergo Framework. it provides you distributed pub/sub messaging. For the rest - feel free to use NATs, depending on your needs.

@halturin Thanks for the reply. I was just asking whether there is a need to implement a particular service discovery to use ergo with k8s, NATs and co to let two ergo nodes discover each other in the cluster.

no need. it has this feature embedded. similar to Erlang's EPMD.

but still, i have a plan to implement kuber's registrar support in the future. not an urgent task, but its in my roadmap.
