We've been maintaining a 5-node Nifi cluster on GKE (Google Kubernetes Engine) in a production environment without major issues and performing pretty good. NiFiKop is a Kubernetes custom controller which will loop over events on NifiCluster objects and reconcile with kubernetes resources needed to create a valid NiFi Cluster deployment. For this to work from outside the Kubernetes cluster NiFi has been deployed to, it is necessary to create Service or Ingress objects to configure Kubernetes routes for these ports. cluster=zk-provider # Specifies whether or not this instance of NiFi should run an embedded ZooKeeper server WARN [main] o.
