orch,cephadm: host search with filters
0%
Description
For the bulk addition of nodes, a search command (or add --dry-run) would be useful. Additionally, for dashboard integration, a list of potential nodes should be presented in order to cherry-pick the specific nodes.
With masks/lengths and fnmatch for exclusion patterns:
> ceph orch host search 192.0.2.0/255.255.255.0 --exclude 192.0.2.1 --exclude 192.0.2.[5-9] > ceph orch host search 192.0.2.0/24 --exclude 192.0.2.1 --exclude 192.0.2.[5-9] # or, reusing a existing command: > ceph orch host add --dry-run 192.0.2.0/255.255.255.0 --exclude 192.0.2.1 --exclude 192.0.2.[5-9] > ceph orch host add --dry-run 192.0.2.0/255.255.255.0 --exclude 192.0.2.1 --exclude 192.0.2.[5-9]
Ideally this should also involve that the host add command supports wildcard, but it's ok if the hosts are still added one by one.

actually I'd like to go the other way around and enable remote hosts to join the cluster by themselves. Similar to kubeadm

That would require some magic tricks to generate the list of hosts, like https://docs.ansible.com/ansible/latest/collections/index_inventory.html or similar.I'm somewhat skeptic adding something like this.

Do we really need this? In most enterprise environments I;ve worked in this type of thing gets jumped on by security teams and network admins.

Without this, the only way of adding multiple hosts in large clusters (N ~ 100s) is launch-and-wait or, even worse, forcing users to write scripts (risks are even bigger... from my old days as a Ceph user I sadly remember myself writing a script to delete & create OSDs with asynchronous calls and causing a lots of issues).
