Multiple ceph clusters.

[TafkaMax]

Hi

I am trying to use this role to setup multiple ceph clusters. The overal logic is good, but I am hitting a little bit of an issue.

ansible-collection-cephadm/roles/cephadm/templates/cluster.yml.j2

Line 1 in 7da4bd4

{% for host in groups['ceph'] %}

This defines to loop over all of the ceph hosts. Could this role be suited to take some variable

cephadm_ansible_group

cephadm_ansible_mon_group

cephadm_ansible_osd_group

cephadm_ansible_rgw_group

You could define your own groups like so in vars.

I have created an example branch here: https://github.com/TafkaMax/ansible-collection-cephadm/tree/add-custom-ceph-group-names

This seems to work for my usecase.

I have defined the following variables:

cephadm_bootstrap_host: "{{ groups['ceph_hci'][0]}}"
cephadm_ansible_group: ceph_hci
cephadm_ansible_mons_group: ceph_hci
cephadm_ansible_mgrs_group: ceph_hci
cephadm_ansible_osds_group: ceph_hci

Hi!

Thanks for your interest! I doubt the multiple clusters scenario was ever intended for this collection. I think you could map multiple clusters against multiple Ansible inventories and possibly share common variables in an auxiliary file.
