I'm not a k8s expert (actually I never really used it), but I believe what you'd want in this care are StatefulSets: https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/ In general, there is a growing number of k8s features that have been introduced specifically to meet the requirements of stateful services, for example Persistent Volumes: https://kubernetes.io/docs/concepts/storage/persistent-volumes/ Cheers, Free _______________________________________________ lxc-devel mailing list [email protected] http://lists.linuxcontainers.org/listinfo/lxc-devel
