Hi,
I am trying to install ceph 'octopus' using cephadm. In bootstrap
command, I have specified a non-root user account as ssh-user.
cephadm bootstrap --mon-ip xx.xxx.xx.xx --ssh-user non-rootuser
when bootstrap about to complete it threw an error stating.
""""
INFO:cephadm:Non-zero exit code 2 from /usr/bin/podman run --rm --net=host

"""""
In the above steps, it's trying to connect as root to the node and when I
downloaded ssh_config file it was also specified as 'root' inside. so, I
modified the config file and uploaded but same to ceph but still ssh to
node1 is not working.
To confirm if I have used the right command been used during bootstrap. I
have tried the below command.
" ceph config-key dump mgr/cephadm/ssh_user"
{
"mgr/cephadm/ssh_user": "non-rootuser"
}
and the output shows the user I have used during bootstrap "non-rootuser"
but at the same time when I run cmd " ceph cephadm get-user " the output
still shows 'root' as the user.
Why the change is not affecting? do anyone faced a similar issue in
bootstrap?
Is there any way to avoid using container with cephadm?
