Ok, I've been digging around a bit with the code and made progress, but haven't
got it all working yet. Here's what I've done:
# yum install cephadm
# ln -s ../sbin/cephadm /usr/bin/cephadm #Needed to reference the correct path
# cephadm bootstrap --output-config /etc/ceph/ceph.conf --output-keyring
/etc/ceph/ceph.client.admin.keyring --skip-ssh --mon-ip 10.8.13.121
# ceph mgr module enable cephadm
# ceph config set mgr mgr/cephadm/mode cephadm-package
# ceph cephadm generate-key
# ceph cephadm get-pub-key > ~cephadm/.ssh/authorized_keys
# echo "cephadm ALL=NOPASSWD: /usr/bin/cephadm --image * check-host *" >>
/etc/sudoers.d/cephadm #Needed to run check-host as part of joining other nodes
At this point it seems to be configured to use the cephadm user. Distribute the
public key to other hosts with cephadm package installed.
However I am now getting errors when trying to add a host with orchestrator or
when doing a host-check:
# ceph orchestrator host add k8shost3.acedatacenter.com 10.8.13.123
Error EINVAL: Traceback (most recent call last):

Again, I'm not sure I've done everything that I need to get things set up. Any
thoughts?
