  remote {
    netty.tcp {
      hostname = 192.168.0.1         # machine IP
      port = 32551                   # machine port
      bind-hostname = 10.100.0.23    # container IP
      bind-port = 2551               # container port
    }
  }
}

Statefulsets are scaled sequentially rather than in parallel. When I scale a Statefulset from one Akka node to five Akka nodes, rather than starting four more Akka nodes in parallel, it’ll start akka-1, wait for it to start successfully, then start akka-2, wait, start akka-3, … and repeat until it’s done. This is not ideal as it may take a while to start hundreds of Akka nodes.
