Akka in Action, Second Edition

13 Clustering, part 2

This chapter covers

• Bootstrapping a cluster in Kubernetes
• Using Split Brain Resolver to automate shutting down nodes
• Creating a singleton actor

In chapter 8, you learned how to create a cluster with seed nodes defined in the configuration. These are fixed IPs. Creating a cluster this way is practical, but it isn’t a setup you’ll use to go into production. This chapter starts with the same idea of fixed IPs to local deployment but uses the Akka Cluster Bootstrap module. You learn how to use this module to create an Akka cluster in Kubernetes using the Kubernetes API.
