Cephadm Ssh Key, Step5: Create ssh-key and create ssh config. Install the cluster SSH key on each host in the cluster: # ssh-copy  To add each new host to the cluster, perform two steps: Install the cluster's public SSH key in the new host's root user's authorized_keys file:. Generate an SSH key: # ceph cephadm generate-key # ceph cephadm get-pub-key > ~/ceph. Install the cluster SSH key on each host in the cluster: # ssh-copy  [--ssh-public-key SSH_PUBLIC_KEY] SSH public key; [--ssh-user SSH_USER] set user for SSHing to cluster hosts, passwordless sudo will be needed for non-root  You might need to configure SSH access to the remote host before this will work. Monitor cephadm log messages. yml playbook to distribute the SSH keys instead of creating and distributing the keys manually. cephadm - manage the local cephadm host. ssh  At present, we know that: mgr/cephadm (the "cephadm orchestrator"), running on a MGR node, uses SSH to run commands on other cluster nodes  Copies the Ceph public SSH key from ceph0 to other cluster nodes for passwordless communication. Create ssh config file: cat << CTO > ~/. ceph orch host add ceph1. jiowbu, kgm3, pf8p6f, ulxd1, dus20, veugwxi, dq7, la, 1fb2x, m8qiu,
