Clustered deployment - Advanced configuration

Configuration for deployment of a hazelcast clustered vyne in a docker swarm environment

Deployment architecture

Where a clustered deployment of Vyne is deployed into an environment with a complex network configuration careful consideration must be paid to how Vyne is exposed to the network and to Eureka for successful cluster creation.

Considerations

Pods running containers within the swarm will be started with multiple network interfaces for the connectivity the networks the service is a member of at a minimum the pod will have the default ingress network and host bridge network.

Ingress traffic to the clustered vyne nodes cannot be load balanced but must be direct to the container
