Hey, sorry, missed this back in its day. We use Wazuh as specified in the FAQs.
About ecloud-selfhost, we have an ongoing community contribution to turn it into an ansible playbook and in parallel we hope to fix the existing version (which seems no longer installs correctly) in the next weeks. When that is done, the manual upgrade guide will also be provided.
FYI @diroots.e
Kind regards,
Arnau
