Hi,
One of the recent changes that Ceph Pacific has introduced is the
removal of support for /etc/hosts on the ceph cluster nodes, that use
*podman* as the container engine (CentOS8+)
This means that name resolution from within the ceph containers now
relies on either DNS, or the host to ip mapping that is created when
adding a host to the cluster with the orchestrator CLI (orch host
add).
The exclusion of /etc/hosts has been implemented using a --no-hosts
setting on the "podman run" command.
Installations that use docker are unaffected.
So if you're planning to use Ceph Pacific with podman *and* need
/etc/hosts to work, it would be great to hear from you!
Cheers,
Paul Cuzner
