The best hands-on guide I’ve read for rook-ceph cluster!
Thanks for the warm comment. We hope it was helpful.
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!
Thank you!
This is real detailed and works
Hello, nice tutoriel ! 🙂 But at the end i ve a problem with “archived”: “2023-05-13 14:38:20.033594”,
“backtrace”: [
” File \”/usr/share/ceph/mgr/nfs/module.py\”, line 169, in cluster_ls\n return available_clusters(self)”,
” File \”/usr/share/ceph/mgr/nfs/utils.py\”, line 38, in available_clusters\n completion = mgr.describe_service(service_type=’nfs’)”,
” File \”/usr/share/ceph/mgr/orchestrator/_interface.py\”, line 1488, in inner\n completion = self._oremote(method_name, args, kwargs)”,
” File \”/usr/share/ceph/mgr/orchestrator/_interface.py\”, line 1555, in _oremote\n raise NoOrchestrator()”,
“orchestrator._interface.NoOrchestrator: No orchestrator configured (try `ceph orch set backend`)”
It’s Really Work. thanks for your guideline.
Happy for you. Welcome anytime!
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!
Did you deploy the cluster using Rook?, or you mean cluster not deployed with rook?
Yes, using Rook.
Thanks
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?
Did you try using our method of creating a new fiile
dashboard-external-https.yaml?
