  2. Totally agree with the comment of @Ghilman. Perfect hands-on guide, well explained (maybe not fully on k8s beginner-level, a bit more advanced) but overall straightforward!

  6. amazing work! I have some questions about how to manage custom ceph cluster with rook. For example, how can I configure the number of replicas in a pool? Or how can I configure the minimum amount of OSDs?

    THANKS!

  7. I like your articles very much!!! Thanks a lot!
    You are describing how to access the rook-dashboard. I was trying to change the servicetype to NodePort or to LoadBalancer with “kubectl edit…”, but to my surprise after a short amout of type the servictype gets somehow automatically switched back to ClusterIP…
    Any ideas?
